Subject: quick question Sent: Thursday, November 30, 2000 20:19:15 From: firstname.lastname@example.org (Tony Bulat) If I choose not to change daylight savings time in the autostar and simply add an hour to local time with all else being the same as it was last summer, will that create a problem with initial GOTO commands? By this I mean the local time is advanced 1 hr., but the difference between local time and GMT stays the same and you lie to the autostar and tell it that DST is in affect. I figured this way you wouldn't have to mess around with the initial numbers (figures) that autostar uses to figure out it's time and place for that evenings viewing. Thanks again for the answer and the best web site in the world on these kind of things. Tony BulatMike here: Well, if you always remember to enter the time wrong (off by an hour), you'll be OK for fixed objects. But the Moon calcs will likely be off. But I don't understand why you wouldn't just change the DST setting once and leave it alone for six months.
Subject: Autostar update on windows 2000 and other complains :-) Sent: Wednesday, November 29, 2000 14:47:03 From: email@example.com In the "Autostar info" section of your site under "Update Autostar: Windows2000, Linux, FreeBSD" I saw a post of someone that did managed to run the version 2.2 of the autostar updater on Windows 2000. Well, it didn't worked for me (on Windows 2000 professional) but I wanted to give some hints to others... When I start the Autostar I will get an "Application Error - The instruction at "0x77fcbfe1" referenced memory at "0x0000000000000", The mem... " First it took me some time to get my hands on the 2.2 version ! The version downloadable from the autostar update page on meade's web site (http://www.meade.com/support/auto.html) is a 2.1 version ! The version 2.2 is nevertheless available (I had to dig a big in the mess of the directories !) at : http://www.meade.com/support/auto/EtxAutostar/auto.exe Included is the version 2.0i (last known version at this date) of the autostar firmware. Hopefully the Meade Autostar is not as bad as the updater and work well (if you don't push it too hard sending commands from a pc) ! The autostar web site is out of date since 07/03/00 !!! only 8 months ago ! Should I mention the orbital elements files which of course can't be used anymore... I guess lots of beginers in astronomy (I though the autostar was done for them ?) are downloading 1 year old orbital elements files trying to track satelites and are quite surprised to find that ISS is not anymore there... Well for them (And I was one of them some month ago (and still a beginer in maaaany aspects !) ) I will remind that most of the satelites are loosing altitude and needs to be regularily put back in the right orbit... it means that elements files are often valid only for a short period (days or weeks). And "Coming Soon" for 8 month has been the "Coming Soon! Autostar Update Java Client for Windows and Macintosh (requires Java enabled browser)"... Everybody still waiting for it ! While Meade appeared to early understand the necessity of Internet upgrades (when the competitor still don't have) I've got the feeling that they still don't really understand that all this have a meaning if they DO provide upgrades ! Windows 2000 has been available for developpers for quite a long time now and is not really different from NT4 and 98 ! So why is this STILL not possible to upgrade using it ? Is it normal that some (good !) people need to PATCH the autostar software to correct bugs (http://www.weasner.com/etx/autostar/as_beep2.html) ? It's probably a ressource issue (it might be difficult to find Software engineers in California) but why not decide to open source the autostar and the upgrader then ! and let the community do the dirty work ! That would be a nice solution but of course a tough "political" decision... Well, having said all that I'm still pretty happy with my ETX 90 and the Autostar but had to express my frustration on some issues :-) ... Thanks for your great site once again mike, as I already told you it was for a lot in my choice of the ETX 6 months ago ! XavierMike here: Yep, Autostar updates have stopped coming frequently. But on the other hand, some users complained about the frequency of the previous updates and their bugginess. So, perhaps Meade is waiting until the next release is fully polished.
yes :-) I hope you're right but frequent updates don't necessarily have to be buggy !

Subject: Proc Trap2 Sent: Wednesday, November 29, 2000 11:26:07 From: LooneyRoo@aol.com Just got that error that I listed in the subject line, and it isn't going away. I've tried, repeatedly, to turn it off and back on again. Nothing is working. I just read an entry on your site about it, but there was no solution to the problem if it didn't resolve itself.... What should I do? ~NoahAnd:
Just did a search on your site for "proc trap 2." I found a link that shows a way to debug the Autostar. Unfortunately, my Autostar is not responding to Hyperterminal... I thought I had a way out, but now I'm lost again....Mike here: Can you get into the SAFE LOAD mode and try re-uploading the Autostar software?
I've been getting alot of advice from Dick Seymour. I tried a Safe Load, but after the installation, the Autostar screws up again. It either goes blank when it should be initializing, or the trap comes back. This is getting really frustrating!Mike here: Try calling Meade first.
before i call meade... i had one question for you. if i hit enter and the downscroll before i turn on the etx, i get a "flash load ready" message. i then start up the autostar update program and click on "new software" (after i click the yes for "safe load"). is this the correct procedure? or should i be doing something else to get the autostar to initialize? the whole proc. trap 2 error occurred in the middle of a download... so that is why it won't start up. but there has to be a reason why the program keeps crashing at the end??? you'll probably tell me to call meade, but i thought maybe i was skipping something that you know about. thanks mike, and take care!Mike here: When you enter the SAFE LOAD mode, the PC software detects that when you start the download. So, it sounds like you are doing it correctly.
And finally the fix:
Dick Seymour: I spent all day (from 12:00 pm - 1:00 am) trying to figure out a way to get myself back online. I decided to think this thing through. I figured that since this is a problem other people have had and have been able to get out of, the problem was probably not with the Autostar itself, but with the Updater. Figuring that I had nothing to lose, I decided to uninstall the Updater from my computer and to unzip the AUTO.zip file that I had saved on my computer to get a fresh start. Well, I tried this and Winzip said that there were files missing from the zip file and could not be unzipped. I then began to think about my computer's history. I contracted a virus about a month ago, and had to manually delete alot of files to get rid of it (Mcafee couldn't just clean the files, it actually made me delete stuff). So I began to wonder if this virus I had contracted had in some way screwed with the Autostar files. I then deleted that zipped file and downloaded the complete zip file from Meade. I then tried a Flash Load one more time... To make a long story short, I'm being asked what country I live in by the Autostar!!! Thank you for all your help! I'm sending this to Weasner too, so that if others have a problem like this, they will know what to do! Take care. ~Noah
Subject: Latest Software-Version for Autostar Sent: Tuesday, November 28, 2000 14:07:54 From: firstname.lastname@example.org (Dr. Ralf Schulz) Ralf here from Germany! I purchased one of the first ETX90EC with Autostar in March 1999 in the US. Because I had version 1.0, I upgraded the software of autostar to version 2.0i. This version has some problems with orbital elements and satellite tracking. After a while, I looked at the Meade homepage, and I wondered, that there is no new software version since March 2000! There are no new Orbital elements or sattelite information since January! Is this really true, or do I have the wrong address? I appreciate some more information on that. Sincerly Ralf SchulzMike here: You got the correct address; nothing new in several months.
Subject: Autostar info Sent: Monday, November 27, 2000 07:03:09 From: Jean-Marc_Herpers@skillteam.com I have recently buyed a meade etx-125. Up to now, I have used it without the autostar with good results. However, I would like to point more quickly sky objects. As I have an IBM thinkpad, I would like to use an astronomy software to guide the etx. I found on internet the software Skymap 7 which includes drivers for etx. However, it's not clear about the way I have to connect the computer with the etx. I looked for inquiries on the meade official site and on other sites but without response. So, may I ask you the following questions : - Is it possible to connect the computer to the etx with a single cable, without passing through the autostar ? I ask you this because I've heard that it's possible. If it's possible, which cable is necessary ? - If the autostar is absolutely needed to control the etx from the computer, I have heard about model 495 of the autostar but also of a brand new model. Do you have information about this new model ? Thank you very much for your help Jean-Marc Herpers Belgium E-mail: Jean-marc herpers@SkillTeam.comMike here: You do need the Autostar in order to control the ETX from a computer. According to information available on Autostar models on the Autostar Information page on my ETX site: The #497 works for the ETX & DS models and #495 only works for DS models, NOT the ETX. There is a new model Autostar for the LX90 8" which has a larger database (probably more than can be seen with the ETX-125EC).
Thank you for the information and the quick answer !
Subject: RE: tracking the sun with autostar Sent: Sunday, November 26, 2000 07:44:13 From: email@example.com (Verreau, Bernie J) To: firstname.lastname@example.org (richard seymour) Thanks, Dick. I'll give your sun-as-asteroid method a try when I have my solar filter. I think it's a shame Meade can't be more forthcoming about programming the Autostar. There's a lot of interest in solar observation this year, with the sunspot maximum and all. Looks like their lawyers are running the show. One of the main reasons I got my ETX was for field use with solar eclipses. I plan to take one to Zambia for next June's totality [my 16th]. Of course there's an easy workaround for solar eclipses. You just set the scope to track the moon. If you're interested, I have a number of non-Meade eclipse photos on my website, home.att.net/~bernieverreau . Clear Skies! Bernie Verreau, Redwood City, CAMike here: Lawyers run the Country as well as Corporations. In Meade's case, you can't really blame them for being cautious. Consider the people that blind themselves whenever there is a solar eclipse even with all the public warnings.
Subject: Check the file sizes! Sent: Saturday, November 25, 2000 23:18:19 From: email@example.com (Paul Loughman) I finished upgrading my #497 Autostar Computer Controller, from version 2.0g to 2.0i. It took me almost two hours, because of a very simple (and avoidable) mistake. The upgrade was done using the Autostar Update Client for Windows, version A2.1. When the program was about 50% completed, it quit, telling me that the Autostar had not completed the upgrade. I had to resort to Safe Loader Mode in order to access the controller (the incomplete upgrade 'crashed' the controller). I tried again. Same result (crashed controller). It was then, that I realized what the problem was: I had downloaded the 2.0i Autostar.ROM and dbase.ROM files. The download completed, but I had not checked the file sizes! The download had not completed normally, so I did not have the complete files. No wonder the upgrade couldn't complete! I downloaded the files again, and checked the file sizes: they were correct; so attempted the upgrade a third time. SUCCESS! So, follow ALL the directions, to include checking the size of the downloaded files. It will save you time, and a lot of frustration! -- Paul O. Loughman
Subject: autostar stalling Sent: Saturday, November 25, 2000 14:36:55 From: firstname.lastname@example.org (Craig Ireland) tonight when using my etx125 and autostar (version g), after about 25 minutes the autostar handset jams. it does not allow any movement of the scope using the cursor keys or does not allow me to use any other menu. all keys are inactive, inc the red led when pressing zero. has any one else come across this??. I have had no other problems and its only happened tonight. regards craig ireland (East Anglia,UK) P.S. mike, you have a great site!!Mike here: A similar problem has been reported before and in fact I've had the Autostar lockup on me. Fortunately, it happens only rarely in most cases but it does force you to go through the alignment process again. Low batteries or just stumbling across a software bug can cause the problem. If you have the cable or a dealer nearby you might want to consider upgrading to the current 2.0i version.
Subject: GOTO Problem on an ETX 125 Sent: Friday, November 24, 2000 00:37:41 From: Roy@mikola.demon.co.uk (Roy Duggan) Thanks for the great site. I have had inconsistent results with the GOTO functions on my ETX 125. Any thoughts/advice would be welcomed. I have read that the axis training is critical so I thought I would try to some experiments to see if I could isolate the problem. I have carefully set the scope base level, and aligned the home position by sighting Polaris in the 26mm eyepiece. I then did a careful alt and az training on Polaris using a 9.6mm eyepiece. I have quite a lot of obstructions to my urban site to reliably perform a 2 star easy align, so for the purposes of this test I opted for a single star align. I based this on a target star around 20 deg in azimuth away from Polaris (I think for the limited test I was conducting, this would not result in any positioning error.) I then moved the scope a few degrees off of Polaris in each direction N,S,E, & W and then selected GOTO back to Polaris, this resulted in what looked like some remaining backlash type of repositioning error that was repeatable but generally put Polaris back someway offset but still within the fov of 26mm eyepiece (but this would quite likely have been outside a higher mag eyepiece.) I then slew the scope on a fast speed setting to around 45deg away from Polaris in 2 axis and hit the GOTO button, I was a little surprised to find that the scope really did not get very close. "The Sky" calculates the fov of the ETX 125 with 26mm eyepiece at 40' on this basis I would estimate the positioning was probably at least 1-2 degrees off. I was a little surprised, as I would have thought that repositioning to Polaris should be almost totally insensitive to any errors on the alignment. In any case after I re-synchronised to Polaris and then selected GOTO a star not that far (perhaps 10deg away from the pole star) the results were a little better and on one occasion I did goto SAO181 and then backto Polaris and got both stars in the fov on the bleep from the autostar. I then lost track of a very clear diagnostic path and tried a few resyncs and slewing to different objects so after this I don't think I can draw any rock solid conclusions, but unless I am wrong it does seem that the scope seemed to suffer significant positional error after the manual high speed slew I certainly got the impression that the pointing accuracy was much better when I first bought the ETX (around 1 month ago); I was really impressed on the first night of use, being able to find a number of meiser catalogue objects which I could never track down on my old 6" Newtonian scope, and I would love to get that level of confidence back. I think it would be really useful to have a diagnostic procedure to simplify the process of working out what is going wrong I would like to hear anyone else's suggestion on a better procedure than I tried and perhaps developing this further as a general test. On my next clear night and when I have the time I will try the following: 1. Double check the site location (which I think is right, as this was taken off of my handheld GPS) 2. Make sure the time is set off of a very reliable source (I use a radio controled clock synched from Rugby) 3. Note the % Battery available (I am on my first set of batteries and these are showing 29% and I have a sneaky suspicion that this may affect performance.) 4. Set up everything with a spirit level. 5. Set the base and OTA to the "Home Position" 6. Align the scope to Polaris 7. Return the OTA to level (using an eyepiece spirit level) 8. Select Easy Align 9. Select one star method 10. Use a known star to be used to test the positioning accuracy (call this Star x) 11. After successful alignment on Star x note the Alt and Az reading for Star x 12. GOTO Polaris 13. On bleep note the alt and Az reading (where the scope thinks it is pointing) 14. Re-center Polaris and note the Alt and Az reading (the difference from the step 13 above should quantify any error) 15. Select GOTO Star x 16. On the beep note the alt and az reading 17. Recenter on Star x and note the alt and az reading (gives the error after returning to Star x) 18. Resync to star x 19. Wonder if all this gadgetry is getting in the way of doing any observing :^). This would at least give some baseline measures of performance of your scope. One thing I do note is that during slewing my scope does not go werererererer but WeereeRReerreeRReerr (if you see what I mean) is this normal? Best Regards, Roy DugganMike here: If I correctly understand how you did your alignment, I think that could be the source of the GOTO errors. As Dr. Leon Palmer from Rigel Systems reminded me when I was first evaluating the Autostar with an ETX-90EC in 1999, the Pole area is one of the worst places to select an alignment star because of the convergence of the Right Ascension lines at the higher declinations. This convergence means that a small error in angular position translates to a large error in the Right Ascension value. Errors in position are compounded and can even result in an opposite alignment when trying to align on Polaris, which isn't precisely at 90 degrees declination. Dr. Palmer advised to use stars that are about 90 degrees (6 hours) apart and near or on the celestial equator for the best results. As to the sounds you are hearing when slewing, the unevenness doesn't necessarily indicate a problem.
Subject: tracking the sun with autostar Sent: Thursday, November 23, 2000 10:18:50 From: email@example.com (richard seymour) To: firstname.lastname@example.org Hi... I saw your note on Mike's site. If you check the Autostar Info page, you'll see my note on how to add the Sun as an Asteroid. http://www.weasner.com/etx/autostar/as_sun.html Then you can get a (pretty close) GoTo. Among the tricks to that are: Park the scope the previous time, so it won't ask to align when you power up. Locate a due-north reference landmark for manual accurate postioning prior to power up (it'll be where the Park operation ends up). That said, I tend to use Mike's method: cover finder, apply solar filter (mine's the Orion), point ETX due north, barrel level. Power up, [goto] some astronomical object to start sidereal drive. (Mercury's always handy for sun-related stuff). Now slew to the sun... using the scope's shadow as your aiming guide. Once there, the tracking should be accurate enough that only a little touch-up every 5 minutes or so keeps it within view. Sunspots are fascinating... have fun, but be VERY careful about the filters and blocking the finder. --dick
Subject: Re: Autostar Tracking Rates Sent: Wednesday, November 22, 2000 08:50:55 From: email@example.com (Rick) Yes , that is the setting I am trying to change. My scope tracks perfect on other objects but seems to lag when on the planets. I just bought a Vector power supply and it provides a more consistent voltage/amp. supply than the AA batteries. In testing it seems to move more smoothly. As soon as my work schedule and viewing conditions cooperate I'll try it out and let you know how I make out.
Subject: Pinout for AutoStar Sent: Wednesday, November 22, 2000 00:05:00 From: firstname.lastname@example.org (Gary A. Ferguson) Does anyone know the pinout for the serial port on the AutoStar 497. I'd like to make my own cable rather than spend $30 on one from Meade. Thanks, GaryMike here: Have you looked at the Autostar Information page on this site or the Autostar instruction manual page on Meade's web site? The info you seek is there.
Thanks! Yup, someone else told me also so I have the info I need.
Subject: Does focus cause slew runaway when Sat Tracking? Sent: Tuesday, November 21, 2000 20:10:37 From: email@example.com (richard seymour) Is it me, or Memorex? If you have an electric focuser, have you ever experienced slew runaway when satellite tracking? On my ETX90/ec with electric focus, v2.0i firmware, if i Object>Satellite>Select>whatever [enter] [goto] and then [enter] to track, it'll start tracking. If i let it get at least 20 seconds into the track, and then press the zero (0) key to select focusing, the slew frequently (usually) starts -racing- along the satellite path (or somewhere else... the key is that it takes off and -moves-). Sometimes the zero key can stop it, and sometimes only the [mode] key can stop it, at the expense of dropping out of Satellite tracking mode. You can test this indoors if you've got some TLEs in your Autostar. Just set the TIME to a few minutes before a pass, select the satellite, and [goto] (for setup) and [enter] to track. After at least ten or twenty seconds, press zero to choose focus (the focus speed symbol should appear on the upper right of the display) IF you have the same symptoms i do, the ETX may start slewing weirdly (or wildly) immediately... you don't even have to press a slew key to change the focus... merely choosing to get into focus mode does it for me. If it's easy to do, please give it a test and let me know the results. This might just be my particular ETX90 and focuser having arguments about who does what. thanks --dick
Subject: go to question Sent: Tuesday, November 21, 2000 06:09:36 From: MREYNOLDS@expl.com (Mike Reynolds) Does the Autostar need the ETX-90EC to be mounted in a polar fashion? BTW: The electric focuser is very easy to install and I think every owner needs one.Mike here: The Autostar allows compatible telescopes to be used in either Polar (equatorial) or Alt/Az mode. For most users, Alt/Az is the better choice.
Subject: Alt/Az Autostar Alignment Sent: Saturday, November 18, 2000 05:29:46 From: firstname.lastname@example.org (Yenal Ogmen) I read about Alt/Az Autostar Alignment in your site. But i think i have some problem because while control panel pointing west, i turn scope counterclockwise till the end. At this point my scope is pointing more or less north (dec circle is on Control panel) so i think this contradicts with what i read in your site. At this point scope should point southwest you said. But my scope does not. Why? Thanks YenalMike here: Well, there are a couple of possibilities. One, the hard stops were misaligned during assembly at the factory. Two, there is some internal obstruction preventing the completion rotation. Just out of curiosity, how many rotations can you make clockwise? It should be about 1-3/4, or end up pointing about SE (with the control panel on the west). If you get this full rotation, regardless of where you end up, there is one experiment you could try. When you hit the counterclockwise hard stop, pick up the ETX and tripod and move it until the ETX tube is pointing SW. This would put the control panel facing SE. The move the tube to the HOME position. See what happens when aligning and GOTOing. Let me know.
Hi i checked how much it rotates in clockwise direction and i found that it completes one turn and 1/4 turn more not 3/4. Why is this so? This is my second scope from Meade. First one was a failure. And so second one? If so i will throw it though my window. Please tell me what to do. Thanks.Mike here: Well, don't throw it through a window. I hate the sound of breaking glass! But it does sound like something is amiss in the hard stop positioning. If you can, take it back to the dealer where you purchased it. If you can't do that, try ANY local (or near local) Meade dealer. If no local dealer, contact Meade. If it is still under warranty, this is your best solution. If not under warranty and you are brave, you can open up the base and see if you can locate an obstruction.

Subject: re: autostar aligning Sent: Friday, November 17, 2000 20:52:36 From: email@example.com (richard seymour) To: firstname.lastname@example.org Hi... I saw your note on Mike's site, and noticed that you talked about "one star aligning" using Polaris. That's not a good idea. It is much, much better to use a star some distance from Polaris. (Sirius, Vega, Deneb, Formalhaut, Altair, Rigel, Spica...) That way, the Autostar gets rotation-of-earth information from the alignment. Aligning on only Polaris only tells it where "North" is, but does not provide fine control of the RA angle. Of course, if you are using Polar mounting, then the "one star" is the star chosen -after- pointing at Polaris. have fun --dick
Subject: Autostar Tracking Rates Sent: Friday, November 17, 2000 12:00:29 From: email@example.com (Rick) Do you know how to change the tracking rate of the Autostar? I have tried to put different numbers in the field called "custom" under the tracking rate menu, but it dosen,t seem to have any effect. I'm trying to get my ETX90 to track Jupiter and Saturn better that that allowed with sidereal.Mike here: Sidereal will work for the planets in normal viewing durations. Are you having tracking problems with stars? If so, you might want to check your latitude, degree of off-level, HOME position, etc. However, I have not needed to adjust the Autostar settings but from what I read, you use the Setup menu-->Tracking Rate-->Custom and enter some parameters. Is that the setting you are trying to change?
Subject: FOCUSING WITH THE AUTOSTAR Sent: Thursday, November 16, 2000 15:43:35 From: firstname.lastname@example.org (gombe) I have noticed that when I hook up my autofocus to the ETX base, and use the autostar to focus rather than the hand unit which comes with the autofocuser, the speed, even at low speed is to fast.

The technology is so inexpensive, I wonder if anyone a has been experimenting with adapting one to other telescope/mounts?

To the best of my knowledge (WARNING: i ahven't opened a new one), the hardware is unchanged for the model 497. There was mention (here on Mike's site) about some update being done for improved operation with the 125, but i never saw anyone post a "i've got a new one!" message. The -software- sure doesn't know new from Old, and MEade still says you can move an AUtostar 497 to all models of the family (scroll thru "telescope model" in Setup) > In otherwords if I clone 2.0g into the one I just bought, > will it drive my scope in a similar manner? yes. and the Cloning only takes 5 minutes! > Will I have to retrain my scope to run with that autostar? > I suppose the training results go into the autostar--but does the > cloning transfewr that info? When you first introduce an Autostar to a telescope, use either the RESET or CALIBRATE DRIVE Setup opearation. That (i believe) tells the Autostar (which has memory) how quickly/far the ETX moves for an applied step command. The TRAIN DRIVES (Alt and Az) is a separate function which uses you to help determine how much BACKLASH (looseness caused by reversing a gear train) exists in your ETX. That is also remembered, and varies from ETX to ETX, but (hopefully) doesn't change too quickly over time. IF you Clone or DOwnload, it's a good idea to redo the CALIBRATE step The Updater frequently forces you to... it RESETs the Autostar, and the ETX barrel will jog to the right and up... that's the CALIBRATE operation. Drive TRAINING may be optional: my ETX90 seems to work pretty well with the "default" backlash value which gets downloaded as a first guess. In fact, my Alt axis is so loose, i cannot do an "honest" training session... if i do, creep-after-arrival overwhelms me. When you CLONE, you're given the option of cloning (a) everything, (b) database only (c) user data only (Satellites, Comets) so it's your call. I'd do everything. >and finally, is there any reason why Meade did not upgrade my autostar >to the 2.0i level? none printable. >Is it worth doing? i recommend v2.0h over 2.0g. 2.0i *only* corrects foreign language operation. > I believe that my focuser will be accessed easier from the autostar > using a higher version, so it might be worth it. > Are their anymore versions coming out soon? theoretically... but i have no idea how appropriate the word "soon" is.

Subject: Alt/Az or Polar mode? Sent: Tuesday, November 14, 2000 23:44:19 From: email@example.com (Yenal Ogmen) Thanks for your interest. I would like to know which mode is the best, ALt/Az or Polar OR it completely depends on the observer. I want to track on objects in the sky and i read in the manual that it can only be done when telescope is polar aligned unless if it is in Alt/Az mode you should press on control buttons often to keep object in the eyepiece. But in Weasner site of ETX someone says that best results can be achieved from Autostar when it is in Alt/Az mode. What shall i do now? Any tips about this? Thanks YenalAnd a response:
Sent: Wednesday, November 15, 2000 00:37:13 From: firstname.lastname@example.org (Liem Bahneman) For 99% of ETX users, alt-az is "ok", as the ETX isn't built nor really capable of the kind oh photography/tracking that Polar mode is geared toward. Polar alignment eliminates field rotation inherent to alt-az tracking, which is required for long-exposure astrophotography. However, since the ETX is too lightweight and inaccurate for such a task, alt-az is normally fine. Also, it would seem that most Autostar firmware revisions perform better in alt-az. However, if you do any sort of imaging, even as simple as a digital camera through an eyepiece, polar mode does have some benefits. When a scope is mounted alt-az, it requires drive correction on two axes, RA and declination. By using a polar alignment, you only need correction in the RA axis. This eliminates 50% of the slop inherent to the ETX's drives. If you're trying to center Jupiter with a quickcam, let me tell you, this is extremely helpful. Another downside of polar alignment is the requirement of a wedge-type tripod, which may be a cost factor. So, its really a judgement call. If you're just skewing around with your eyes all night, you're probably safe with alt-az. If you're doing any sort of imaging, I recommend Polar. - liemMike here: I agree with Liem. Most users do not need to use Polar mode when they use the Autostar. Only in special cases is it required.
Sent: Wednesday, November 15, 2000 14:02:46 From: Etxstargazer@aol.com Hi Yenal, What is best for an accurate GoTo is Alt/Az. For some reason, GoTo is not always accurate in polar mode. I would personally rather use my scope in polar (because I prefer the easy tacking, and also works better for photography, and because all of the scopes I have previously owned have been polar also), and I was very disappointed with the results I got in polar mode. Once you can complete your alignment, and find an object, traking is a breez and there are rarely ever any mistakes. Alt/Az is overall the better choice, because GoTo is always accurate, and traking is acceptable 99% of the time. This is my opinion, and I think that Alt/Az is much easier to use. Hope this helps. Clear Skies, Taylor Chonis
Subject: Re: More technical questions Sent: Tuesday, November 14, 2000 11:42:07 From: email@example.com (Tony Miles) This is in reference to Emory Braswell's comments in the Autostar feedback section of your site. I was told by a Meade rep that all ETX Autostars being shipped directly from Meade only have Version 2.0g. He said that the difference between 2.0g and 2.0i are so insignificant that Meade doesn't ship out Autostars with the latest version. I don't know. I think there's quite a few difference between the two versions. I guess it's up to the individual user if whether or not they want to upgrade. It sounds to me that Meade has a whole bunch of 2.0g Autostars laying around and they don't (for whatever reason) want to spend time upgrading those models to the latest versions. I'm curious as to whether or not someone who buys an Autostar right now in the retail storefront gets the Version 2.0i? Thanks, Tony Miles
Subject: Autostar 2.0 software bug? Sent: Tuesday, November 14, 2000 09:35:59 From: firstname.lastname@example.org (Ulrich Nehmzow) I think the Autostar 2.0 software has a bug, but I wonder whether you can confirm this from other feedback you have received. My Autostar crashes in any of the three "tour" modes if you press any other button but "Go To". The error message typically is "trap 2", sometimes the computer crashes without message. If you go into "Tonight's best", for instance, and press "Enter" on any object offered, the Autostar crashes. In the other two tour modes it crashes anyway, regardless of which button you press, so they are even worse. If you know anything about this problem, I'd be interested to hear. Kind regards Ulrich.Mike here: I don't see this; I have 2.0h installed. I don't recall seeing this problem. Can you reload the software?
thank you for your quick reply. Well, it looks to me like the software in my Autostar is corrupted, because the computer definetely crashes on any of the tours. At the moment I can't download the software, because I have no cable yet - I've only just started with the ETX. Thanks again, and many greetings from ManchesterMike here: If there is a dealer close to you, you might be able to get your Autostar cloned from one at the dealer. Or swap it.
Good idea, thanks for the suggestion.

Subject: More technical questions Sent: Sunday, November 12, 2000 19:47:18 From: firstname.lastname@example.org Mike, thank you for your quick answer and your research. I guess I was hoping that for someone it would be an easy "of the top of their head" answer. I will certainly follow your lead and and use the web more. Now, I have an autostar which I had sent in with my 125 (twice in 9 months) to have a number of things straightened out before the warrenty ran out. They sent them back to me and things have been much better. The autostar now had version 2.0g installed (up from 1.3b). Since I only had occasional wild slewing--maybe once a night-(I use a small 12 V lead-acid storage battery) I never complained about it. So I don't know if they did whatever the fix is for that problem since it still occasionally slews wildly. As you know I've been playing with the autostar (powering it directly etc.) and since I didn't want to fry it and lose out on using it for it's intended purpose--I recently bought another one in a camera store. It has 1.3b installed in it. Now my question--do you think that the one I sent to Meade has some kind of updated hardware in it? In otherwords if I clone 2.0g into the one I just bought, will it drive my scope in a similar manner? Will I have to retrain my scope to run with that autostar? I suppose the training results go into the autostar--but does the cloning transfewr that info? and finally, is there any reason why Meade did not upgrade my autostar to the 2.0i level? Is it worth doing? I believe that my focuser will be accessed easier from the autostar using a higher version, so it might be worth it. Are their anymore versions coming out soon? I suspect you're now feeling--so many questions--so little time! I've spent a lot of the past year reading your site and learning enough to be able to have wonderful evenings and now I'm beginning to have urges for doing more serious things. Now that I'm getting close to retirement, I am returning to my teenage interests. During which I had ground and figured a six inch mirror in an apartment in Brooklyn. Never got to use it except to project sunspots and solar eclipses on the wall. Since then I have been unable to do much except make a living (in Biophysics), raise a family, and read about the amazing developments that have brought astronomy at such a cheap price and little hassle (compared with the late 40's) to the average hobbyist! Sorry to spout on but I am feeling quite happy having been delighted by gazing at some half dozen beautiful double stars tonight. Came in to warm up and read the answers to my questions asked only this afternoon. Thanks so much for your caring to run this site! Regards, Emory BraswellMike here: If you just received the Autostar back from Meade it is surprising that it doesn't have 2.0i. You probably want to upgrade and clone. Retraining is required whenever you switch Autostars or telescopes. Seems to be a good idea when upgrading the software. I have 2.0h and still get the random slews with the ETX-125EC on loan from Meade. Occurs once or twice a night; I just GOTO some object (or use the last selected object), re-center it, and SYNC (hold down the ENTER key for a couple of seconds). Seems to be the quickest way to recover from a random slew. As to a new version, including that Java-enabled one, we are all waiting. Maybe I'll find out more this coming weekend when I'm at the Oceanside Photo and Telescope "Meade Day".
Subject: hard stop Sent: Sunday, November 12, 2000 06:12:15 From: email@example.com (suliman rajhi) today, i have different problem. when i make aligning for my etx125 it moves to the right(or to the left according to the star position)and never stop until it reaches the hard stop. i trained the telescope many times but no changes. by the way, i use 2.0h version. also,i reloaded my autostar again and still the same problem. thanks sulimanMike here: I assume you started in the proper HOME position (rotated the scope clockwise and counterclockwise appropriately), and have the Autostar set for your model telescope and proper date/time/location. Try reversing the position of the control panel; normally it is placed on the west side so try it on the east side. Then do the HOME position and aligning. Let me know the results.

Subject: Re: Me and my Mac Sent: Friday, November 10, 2000 02:00:16 From: email@example.com (Daniel Forslund) Just wanted to let you know how my troubles with Starry Night (Mac) and the ETX have panned out. I've finally updated my Autostar by using a friends PC. I think the update itself was a success, at least it now indicates version 2.0i. However, I have no idea if it successfully updated the star/object database, it never indicated it and I saw no way of doing it in the software. It was pretty confusing, so it might very well have been operator error. As for the compatibility with Starry Night, it's better but still not good enough. The ETX successfully slews to the correct target in about 10% of the tries. I've trapped the communications and it often responds with "0" to the sd commands and sometimes to the MS command as well, indicating some kind of error. It can't be the cable since the update worked, so it has to be something in my setup or that the infogenie plugin isn't compatible with the ETX. I'm using a G3 laptop having the communication run through USB->Keyspan Adapter->Soldered Cable->Autostar. If anyone has any info on any incompatibility between the ETX and LX200 protocols, I'd be very thankful. Also, all info on use of Starry Night and the ETX would be very welcome.

Thanks for your help and to Mike for his site! Well, i start with the download package from Meade. And rip into it with hex-dumpers, disassemblers and Word. Actually, there are two approaches: the idealized catalogs (referenced from www.wolfe.net/~workshop/astro/hr.html and http://www.weasner.com/etx/autostar/as_db.html ), are already in near Excel-ready form (use Fixed Field import) (put a .txt extension on the file and the Text Wizard will recognize it and help). The READMEs give data field location keys. Meade doesn't have -all- of any of the catalogs in the 497 Autostar. (the one which will come with the LX-90 has twice the memory, an advertised 32,000 objects, and the LX-200 has 65,000). The 497 has a megabyte of RAM... about 25% of that holds the program, the rest is given over to the fixed and user-addable data areas. My own "hobby" is the understanding of how the program works, with only a cursory amusement as to what the database itself contains (or doesn't contain... a number of my notes to engineer@meade have been quibbles about missing items and indexing methods) For example: the stars are from the Yale Bright Star Catalog (BSC), but Meade chose the SAO numbering sequence as their access method. Peachy... except for the fact that there are stars in the BSC which don't have SAO designators. So you can't reach them! There are at least 3 stars in the Autostar with SAO values of zero... which the SAO entry screen won't accept as a valid number. (locating any of those three is left as an exercise for the student). What goes where in the database, and where the database is stored, varies from firmware release to firmware release. Sometimes wildly. Probing Meade's website gives the firm impression that future versions will be language-specific, which will release some storage from multi-lingual support for other purposes. The Autostar 497 claims a bit over 14,000 objects. The native BSC is about 9,000 stars. The NGC is about 10,000 items. The SAO listing is 250,000. More of my natterings on this are available from Mike's site as the "Autostar Database" and "More..." links from http://www.weasner.com/etx/autostar_info.html The LX-200 command set provides for the PC to be able to access the LX-200's libraries. Those functions are not implemented in the Autostar. It'll only ever admit to M31. Have fun... it's a good puzzle for cloudy nights... --dick
Subject: Autostar and LX200 commands Sent: Saturday, November 4, 2000 11:22:20 From: firstname.lastname@example.org (richard seymour) To: email@example.com (Daniel Forslund) If you check http://www.weasner.com/etx/autostar/as_lx200.html you'll see the ETX-adjusted list of rs232 LX-200-like commands. > :GR# / 01:45:4# > :GD# / +36 DF26'# Get current telescope RA and Declination. > And the nonworkin "slew": > :Sd +49*52'44"# > :Sr 3:24.4# > :MS# Those are the "Set Object RA and Set Object Declination commands. The :MS# means "Move to Object" (coordinates set as above) So the communications you're seeing are valid. Your trapping did not show the Autostar's -response- to them It should reply to the Sr and Sd with a "1" if it accepted them. "0" if it didn't. The response to the MS is more complex. HOWEVER: If the sidereal drive is not already running, the Sr and Sd can operate as Az and Alt instead of RA and Dec. You have to manually align and [goto] a non-terrestrial target to engage the sidereal drive and proper coordinate interpretations. Also, if the commands are sent too frequently the Autostar can misinterpret them. IF you use Hyperterminal (or any keyboard-to-rs232 program) to talk directly to the Autostar, you can issue Gr and Gd commands, which should return the Object's coordinates (not the ETX's current coordinates) You are also running an extremely old version of the firmware.

Subject: re: powering the solo Autostar Sent: Wednesday, November 1, 2000 22:23:47 From: firstname.lastname@example.org (richard seymour) To: email@example.com Hi... I saw your note on Mike's site... First off: You said: > I am not very good at this so is there any cable etc which > I could buy off the shelf? I DO NOT RECOMMEND DOING THIS IF YOU ARE NOT USED TO DOING SUCH THINGS!!! You can (and probably will) damage your Autostar. Dead. That's a $149 lesson. It's far better to play with (much) cheaper things to get used to doing things with hardware and wiring (example: i just opened my autostar and took careful ohmmeter readings to answer this posting... and even as gentle a tool as an ohmmeter could have destroyed my Autostar!) Most folks who are willing to poke inside the hardware have years of burned fingers and equipment sacrificed in learning what (not) to do. I'm all for people playing with (and inside) their Autostar and ETX, but it can be a very expensive learning experience. Let's look at operating the Autostar without the ETX: Early in its start-up sequence, the Autostar checks/asks the ETX to determine its type. The 495 gets downright shirty and refuses to run if attached to an ETX90 or ETX125. Soo... i don't really know if the Autostar will work at all if running without an ETX attached. It's one of those things i just haven't gotten around to testing (but i -am- curious... please report your experiences... such as: what color -was- the smoke?) One correspondent was using a 497 on an ETX60at, and tried giving the Autostar its own power supply... and, as far as i can tell, fried the signal drivers in the 497. You are treading very iffy waters. -that- said, the critical wires are the outer two of the 8-wire connector. Rather than draw pictures which can be misinterpreted, i'll put it this way: the pin on the edge of the 8-wire connector closest to the "9" (nine) key on the Autostar's keypad is the ground wire. The pin on the other side (closest to the "7" (seven) key, adjacent to the rs232 connector) is the +12volt wire. The Autostar will run with about 8 volts, so why not use an 8 or 9-volt supply? AND PUT A FUSE IN THE WIRE!!! about 0.2 amps should be adequate. One reason i gave my answer with the "9" and "7" keys is because (if you read some of the year-ago postings here on Mike's site) many people who built their own rs232 cable set GOT IT BACKWARDS!!! (me, too!). Despite clear and correct pin-out diagrams, lots of us eventually did (or didn't) do the mental-flip and swapped the wires. On the rs232 port, that's not too deadly. On a power cord...it'll kill the Autostar ... within milliseconds (the fuse may not be fast enough). Having my/your ETX powered up while entering satellites, etc., isn't -that- much of an effort. Having your Autostar smoke might be. good luck, take care, think more than twice before trying this. --dickAnd more:
re: powering an Autostar without its ETX attached. ...of course i couldn't resist... So i tried it. And it worked (or, at least it thought it was working). It asked for the time and date, and, since i'd PARKed it last night, it went directly to Select>Object. I was in a bit of a rush (it'd taken some time to locate the not-quite-crunched-enough 8th pin on my "suicide cord" rj45 cable.), all i did from there was ask it to PARK again... and it said "Slewing..." .... and thus it remained whilst i put on my jacket, doused a few computers, and prepared to leave. Tapping [mode] got the beep and "Parked... turn off power" message. When i next turned -on- the ETX (with Autostar reattached), it had the home position 360 degrees out of phase, but i'll forgive it. I (naturally) didn't follwo my own good advice about voltages and fuses (somebody had moved the current-limited adjustable power supply) so i used a 12v battery dug out of the "dead batteries" box. have fun ... don't try this at home (do it at work) --dick
Subject: Polar vs. Alt/Az Sent: Wednesday, November 1, 2000 22:20:09 From: firstname.lastname@example.org (richard seymour) To: email@example.com Hi... I saw your question on Mike's site, and thought i'd comment: I use my ETX90/ec (with Autostar) almost exclusively in Alt/Az mode. If you're into chasing Satellites, you -have- to use Alt/Az. I find Alt/Az a lot easier to set up, use, position my body around, etc. Polar requires (potentially) more careful setup (even "one star" alignment -also- requires pointing at Polaris). Polar requires extreme body contortions to reach the eyepiece when looking at things between Zenith and the North Celestial Pole (Polaris). Even the argument of "it should track better, since only one axis has to move" isn't correct... if the alignment tells the AUtostar that it has to fudge Dec to track an object, it will. So the Dec axis may move a little bit during long tracks. And, depending upon your latitude, you may not be able to access the extreme southern edge of your sky! The ETX can only dip about 20 degrees below the celestial equator, so anything below Dec -20 will be inaccessible in Polar mode. Polar -is- desirable for any photographic work using exposures longer than (say) 5 minutes. Otherwise the image will rotate in the eyepiece. For visual work, this isn't a factor. (well, if you look at the sun at various times during the day, it's a puzzle to figure out which side is east/west/north of the image).(ditto the moon). Alt/Az also has the MAJOR advantage of -not- requiring a tripod! Any level surface will do! (i only bought a tripod after a -year- of owning my ETX and Autostar). This makes the ETX much more portable. have fun --dick
