Subject: polar alignment Sent: Wednesday, July 31, 2002 11:02:42 From: firstname.lastname@example.org (will te winkel) I have been in Detroit (Michigan) the last three weeks on holiday. I purchased a Meade # 887 tripod with #889 adapter for my ETX125 with Autostar #497. I read the information on your website for polar alignment, but I have a problem. With the autostar menu I go to the select items 1. setup telescope; 2. Mount. Than I make the choice for polar and set for enter. But I does not work. The display still shows alt/az. What am I doing wrong? Please can you help me. Will te Winkel The NetherlandsMike here: The ">" pointer doesn't always "stick" for some Autostar selections but the selection has been made. When in Polar mode only the Right Ascension drive is run for tracking so if you don't hear (or see) any movement in Declination while tracking then you'll know you have Polar selected. Also, since the Autostar knows nothing about the physical setup, if your alignment stars are properly pointed at then, unless you at the poles, then the Polar mounting mode is selected.
Subject: Autostar does not have my LXD 55 model Sent: Wednesday, July 31, 2002 7:21:15 From: email@example.com (Lynn Laux) I got my new 5" LXD 55 refractor last Thursday (at last)...and when I was initializing the Autostar, I noticed that when the prompt for my telescope model came up the Autostar menu only showed three: LX90, ETX90, and ETX125. Help! Of course I live in the Midwest and have to wait for Meade to open up this morning but I was wondering if there was a quick fix in order to get this to work, or what. Do you think I should order the #505 cable connector kit? Thanks! By the way, views through this scope are spectacular after my 3 inch Vixen!! LynnMike here: Since I don't have a LXD I can't answer from experience. Perhaps you need to go to Meade's Autostar Update page (http://www.meade.com/support/auto.html) and download an Autostar update. To install it into the Autostar you'll need the proper cable. Or perhaps, just a RESET will do it.
Subject: New Autostar Comet Directory Sent: Tuesday, July 30, 2002 23:21:32 From: firstname.lastname@example.org (Clay Sherrod) A quick note to let you know that about midnight the Harvard Ephemerides were updated for the Autostar to include 135 comets, already configured for instant loading into the Autostar ASU 3.51 program....this will work by merely copying the file and then importing directly into the ASU while selecting the "Delete Existing Files First" box. This list DOES include the elements and orbital path for the new comet Hoenig 2002 O4. You can find the new listing for Autostar at: http://www.minorplanetcenter.org/iau/Ephemerides/Comets/Soft16Cmt.txt for Starry Night Pro, the direct URL is: http://cfa-www.harvard.edu/iau/Ephemerides/Comets/Soft07Cmt.txt but note that this requires some file manipulation prior to installing into the Ephemeris folder for that program.

Subject: Updating old Autostar Sent: Tuesday, July 30, 2002 12:59:49 From: email@example.com Meade gove me your website to assist me in updating my autostar controller for me meade etx90ec telescope. My 497 autostar is version 1.0 thus meade's autostar update 3.51 cannot communicate with it. Can you assist me in upgrading my crontroller to a version that can work with the new one at meade's website? Thanks, Marc ______________________________ Marc Fromm Computer Systems Person University of Montana--WesternMike here: All the older updater and ROM files are archived on my ETX Site at: http://www.weasner.com/etx/autostar/as_archive/downloads.html. Try using the Autostar Updater 2.4 to bring the Autostar to 2.1ek and then the latest version from Meade's site.
Subject: Re: Re: Post for Autostar feedback page Sent: Saturday, July 27, 2002 20:25:05 From: firstname.lastname@example.org (John Welch) Thanks for all your help and patience Mike. It appears we were simply having difficulty getting the autostar into flash mode. It's one of the first units and the original manual was pretty slim, lots of vital but missing information.We managed to update and the units working flawlessly now. Thanks again, John
Subject: Autostar(searching the sky) Sent: Saturday, July 27, 2002 10:24:19 From: email@example.com (Marcelo Amoretti) Hi, Ive been with this question for days, and I was wondering if you can help me!! Ill buy a Meade newtonian-telescope with a 400mm aperture!! I can choose two of this kind!! I dont no if I buy a equatorial with 2 motors, or buy a dobsonian mount with the Autostar Eletronic System!! If I buy the equatorial how can I put the Autostar Eletronic System??? Thank you!!Mike here: Steve Bedair has some Autostar info for non DS/ETX telescopes. Unfortunately, his ISP went under and he is still looking for a new host for his info. So the link on the Astronomy Links page is current dead. I'll update it as soon as I hear back from Steve. If you buy one of the new LXD models you'll get an Autostar with it.
Subject: re: autostar alignment problems Sent: Thursday, July 25, 2002 21:05:04 From: firstname.lastname@example.org (Kenneth Blackburn) Say you have been trying to help me with troubles on my new autostar on the LXD55 8" Schmidt - Newt I tried a one star align and it kept telling me that polaris was below the horizon, does that give you any tips as to what may be going on? I am calling Meade tomorrow, anything I find out I will relay to you for other users. I just kind of think that maybe they are slapping these new LXD series together too fast. You have an excellent page! I am going to search it thoroughly for any other things I might be experiencing. Thanks Ken BlackburnMike here: I don't think Polaris is an alignment star.
Subject: Post for Autostar feedback page Sent: Wednesday, July 24, 2002 19:31:01 From: email@example.com (John Welch) ETX Autostar 497 problem with winxp I've tried everything I can think of to get the autostar software to recognize the device with no luck. Tried different com ports, settings, removing other devices etc. There are no irq, dma or memory conflicts. The software says it can't find the device on the com ports, however after searching it then finds it. Tried it in safe mode and still nothing. That's as far as it will go. Does anyone have any ideas or suggestions? Thanks!! JohnMike here: What version of the Autostar Updater application are you using? 3.51 is the latest on Meade's site.
I'm using 188.8.131.52, we downloaded it earlier in the day.Mike here: If you search the Site for "Windows XP" (using an exact match) you'll find some comments about Windows XP and the Autostar. Maybe something there will help.
Subject: re: Meade LXD55 8 SCHMIDT NEWTONIAN Sent: Monday, July 22, 2002 21:37:03 From: firstname.lastname@example.org (Kenneth Blackburn) Say, I recently recieved a new Meade LXD55 8" schmidt newtonian with autostar. Have you heard of much troubles with this scope and autostar? I have not been able to geta sucessful alignment. When I try to an easy align I undersatnd the manual to say autostar will choose 2 alignment stars ans slew to them but it does nothing. I have also had cases where the autostar just seemed to shut itself off in the middle of something, or to just freeze up with a blank red display. Am I wrong that the autostar picks to stars on easy align? when I go through the steps and it scrolls the message to set polar home for german mount relock axis and hit enter it just displays a d and an n and a negative sign and does nothing. Thanks for any help I am so ready to begin finding some deep sky objects but know I never will until I have a successful alignment. Thanks Ken BlackburnMike here: I'm not certain what the problem might be unless a connection is bad or the Autostar is bad. Can you RESET it from the Autostar menu?
I have reset it from the autostar menu but it didnt seem to have an effect, to me the conectors at the bottom of the controller maybe move around more than they should. I will call Meade, it is a pain that they dont have tech support via email, I work hours that makes it difficult to call them. The way the unit freezes, blacks out in the middle of things and other problems I suspect a bad connection or something. Am I correct on the easy align though? That the unit should choose two stars and prompt me when to center them? Thanks again Ken BlackburnMike here: Does sound like a potential cable or connector problem. And yes, with the Easy Align, the Autostar picks and slews the telescope to one or two alignment stars, which you are then prompted to center in the eyepiece. Let me know what you learn from Meade.
Subject: Scope parking problem Sent: Sunday, July 21, 2002 17:06:11 From: email@example.com (Loupwood) I have just seen Hank B's post under Autostar Info, I have the same problem with my new 125 , Could it be that when the scope is first aligned to the home position, it remembers the time of that alignment so after say, 2 hours or so of viewing you go to park it, does it maybe go back to that exact time of the first alignment and in doing so it will be a little further to the west because of the earth's rotation. Regards PeterMike here: It puts the telescope into a known position, which in my case as always been the HOME position. I'm running version 2.3Ea.
thanks for your reply, I am running 25ea with the latest Autostar ( I assume there is no difference).
Subject: Laptop and ETX125 Sent: Sunday, July 21, 2002 14:36:38 From: Jt_Smithuk@btopenworld.com (John T Smith) Firstly, GREAT SITE MIKE!!!!!! Glad to have found it. Next, what software runs the 125 from a pc or laptop??? I found out tooooooooo late that the software given with my ETX-70 wont run the 125!!!!!!!!!!!!!. JohnMike here: There are several applications for Mac OS and Windows that can drive an Autostar-equipped ETX telescopes. I've not compiled an exhaustive list of them but some are discussed in the articles "ETX/Autostar Compatible Software" and "Autostar Control - Starry Night Backyard" on the Autostar Information page as well as some reviews on the Accessory Reviews - Software page.
Subject: Precise location in longitude and latitude Sent: Sunday, July 21, 2002 12:47:37 From: firstname.lastname@example.org (PHILIP LEWIS) I have anvETX90EC for almost two years. I just got your book, USING THE MEADE ETX the other day. I read in it that I can set my Autostar memory for the precise locationformy viewing.I did not know this before and have ben using a location of the nearest city to my, about 50 kms distant. How do I set the precise location. I have tried with the Autostar but don't seem to be able to bring up the program on the Autostar to do this. Thanks. PhilMike here: Select Setup --> Site --> Add. Or you can Edit an existing entry.
Subject: re: Scope parking problems Sent: Friday, July 19, 2002 21:49:50 From: email@example.com (Richard Seymour) To: firstname.lastname@example.org Two things come to mind: (a) what version is your firmware? ( Setup > Statistics > [enter][scroll up] Some older versions (2.2 early) had definite problems in the PARK code. (b) low batteries? That can do it, too. However the "perfect" slews vote against that. have fun (just never stop!) --dick
Subject: Scope parking problems Sent: Thursday, July 18, 2002 14:11:02 From: email@example.com (Hank) I continue to find your site helpful. After a Supercharge and a vacation to really dark skies (Land Between the Lakes, Golden Pond Kentucky), I am truly impressed with the ETX125. After returning home and setting the scope back up in the living room (I love to show off its deep blue color), I decided to take it out on the deck and catch Venus and M13 for a brief night of viewing. Never having used the park function I decided to give it a try after a half hour of viewing. I selected Park Scope and pressed the enter key and it quickly slewed level and started rotating back towards north (Alt/Az setup). However it stopped a full quarter-turn to the east of north. Perplexed, I set it up again, aligned with two stars and hit a few Messier Objects. I "park"ed scope again and basically got the same results. What gives? Any clues? The slews were nearly all perfect. Hank B.Mike here: Did the telescope hit a hard stop during the parking? If so, then the telescope was not in the proper HOME position when you first aligned it. If it wasn't a hard stop, that's a strange one. What happened went you took it out of park? Did it work correctly?
It did not hit a hard stop. It also does not come out of park correctly. After a short viewing session last night (too many clouds), I may have a lead. The slewing is getting worse. If you realign it works fine maybe - the next time not at all. If it works after a realignment it goes back to the home position properly. I think I may have an encoder issue. I am going to pop open the bottom tonight and see. When it was Supercharged, some cat hair was removed from the gear train. I have three cats and no one is quite sure how the hair made it inside!! More info after some exploratory surgery. HankMike here: OK, lets try the obvious fixes: RECALIBRATE, RESET, RETRAIN. Let me know.
Subject: re: Autostar query Sent: Tuesday, July 16, 2002 7:41:47 From: firstname.lastname@example.org (Richard Seymour) To: email@example.com The display has two other controls, under the Utilities section of the menus (scroll UP from Select/Setup, or down from Glossary). There you will find Brightness Adjust and Contrast Adjust. Set the brightness to your taste, and then play with Contrast to improve readability. Temperature (low=less readable) has a direct effect. That usually becomes a major factor below 5 C. good luck --dick
Subject: re: ETX-125 _Autostar problems Sent: Tuesday, July 16, 2002 7:39:34 From: firstname.lastname@example.org (Richard Seymour) To: email@example.com The description you gave matches the Autostar having a problem receiving feedback from the Alt encoder. A "quick fix" is (sometimes) to simply reverse the HBX cable, end-for-end. Also, take it to a RadioShack or computer netwroking shop somewhere and have them "crunch" the end connectors in their crunch tool. (they're "RJ45" connectors). That may fix it. good luck --dickAnd:
Just to keep you up to date, I took the external cable from my LX-200 and swapped it with the 125's autostar cable and it works perfectly. Thanks, and now I can look into the updates. Scott- NH
Subject: ETX-125 _Autostar problems Sent: Monday, July 15, 2002 12:04:09 From: firstname.lastname@example.org (sdk) I recently inherited an ETX-125 w/ standard and autostar controllers. The standard controller works great. The autostar controller, upon initialization, gives either a motor failure error (altitude) OR, just begins to step up the altitude ...up, up, up, up, up until I have to shut down the power. I've reset several times and can't train motors or calibrate as I can't get that far along. Anyone have similar a experience? Scott - NHMike here: Try changing the batteries. Low batteries can cause similar symptoms.
Thanks Mike but that's not the problem. I think I have it narrowed down to the cable between the autostar and the scope....I hope.Mike here: A bad connection could cause strange problems. Also, a corrupted ROM. Can you update the Autostar?
Subject: Autostar query Sent: Monday, July 15, 2002 4:22:23 From: email@example.com (Excalibur) Eell the weather here in Auckland has been atrocious for the last 3 months so the ETX90 has had little use. Fortunately though, the last two nights have come right and I have had crystal clear skies, but it has been very cold manning the scope into the early hours. The ETX continues to perform very well and I am still getting over 90% accuracy in my (easy) alignments. One issue has started to appear with the Autostar. During the last three or four viewing nights the second line of the Autostar is becoming unreadable when scrolling text. At low scroll speed the text is fine (but I never use slow speed as it is just too slow). This is a marked change from its usual bright display. Iím running on power so its not a battery issue. I also noticed the problem start when the weather was warmer so I donít think its a temp issue. Any suggestions? Thanx again. David HrstichMike here: If the text is only garbled on a higher scrolling speeds then I suspect something is garbled. Try a RESET. If that doesn't work you may have to reload the Autostar ROM. If that doesn't fix it then your Autostar hardware may have a problem.
Subject: re: Meade Starfinder Sent: Friday, July 12, 2002 6:54:48 From: firstname.lastname@example.org (Richard Seymour) To: email@example.com IF you look at the "patches" area of Mike's Site, ( http://www.weasner.com/etx/autostar/patches/v25Ea.html ) you'll see patch kits which -add- the 4504 to the 495 and 497 Autostar's firmware. Which would let you use a 497 to control the 4504. If you wish to use the Starfinder, you need to buy a Meade 506 cable/converter unit. It is not a simple plugs-and-wires like the 497's 505 cable. With a 497 and 505, or a Starfinder and 506, you can use the command set defined at: http://www.meade.com/support/CommandSet.html with commentary at: http://www.weasner.com/etx/autostar/as_lx200.html to control the STarfinder (or 497) from your PC. The "internal" command protocol from the Starfinder to the motor kit is a modified version of the Phillips I2C bus, and (even though i can provide some of the commands) has never been fully successfuly driven (that i've heard of) by a hobbiest. (we have managed to send one or two commands, but never full two-way clean control). The yahoo egroup http://groups.yahoo.com/group/Meade4504Telescopes/ is a forum dedicated to the 4504, the 114eq, and their usage. In the US, a 495 can frequently be purchased for a price equivalent to the 506 cable/converter, and offers more capabilities (and a numeric keypad!) have fun --dick
Subject: Meade Starfinder Sent: Thursday, July 11, 2002 11:01:30 From: firstname.lastname@example.org (Josh Blake) I have a meade 4504 4.5" reflecting telescope. When I purchased it, it came with a motor drive system and a Starfinder control unit. As the Autostar had to be incompatible with my telescope, I was hoping to design an interface that would allow me to connect it to my computer and to my Palm m105. I found an article that had to do with the 4504 and its Starfinder, but I found it to be irrelevant to what I was looking for. To clarify things, I was wondering if you have a pin layout for this specific handheld controller, and possibly the command structure (If not similar to the Autostars). The Starfinder looks almost identical to the Autostar except it is missing the numerical keypad (Buttons: Enter, Mode, Go To, Four arrow keys, an second up and down arrow key [to scroll] and a Speed/Help button). I would appreciate any help that you could offer to me. Sincerely, Josh Blake
Subject: Autostar and Autoguiding with a Webcam Sent: Wednesday, July 10, 2002 4:26:24 From: email@example.com (rlanzet) I have an SC 8" on a GEM with Autostar and DS-Motor as Steve Bedair Project. To take deep-sky photos, i connect a Webcam to telescope and i want to hand guide or autoguide with AstroArt software. But i note that, after polar alignement, when i try of hand-guide, for declination, i set the velocity 1X on the Autostar, there is no problem and the correction is linear after the pressure on the keypad of Autostar; wheareas in AR the correction of the guide, with the pressure on the keypad of the Autostar is not linear and to shift the star in the cross it needs to keep press the keypad a long time, naturally having a loss of guide. Naturally the same things come with Autoguiding, yet more worse. I hope to be clear to explain my problem, and i send you king regards. RobertoMike here: This may be due to backlash in the gearing. You can try adjusting the percentages; see the article "Setting Percentages For Better Tracking" on the Autostar Information page.
Subject: Re: Only slew speed (Autostar pages) Sent: Tuesday, July 9, 2002 10:16:26 From: firstname.lastname@example.org (Uckfield Judges) I was just browsing around the site and I found this in Clay Sherrod's warning about hot summer weather and Autostars. 3) speed settings on AutoStar (the number keys "9" fastest, "1" slowest become totally inoperative and everything runs at the fastest speed when AutoStar becomes overheated; NOTE: letting the AutoStar cool down as above DOES NOT always result in your speed function returning; and so, 4) a total RESET (obviously requiring all new user data entry, owner info., site specifications, telescope type AND "Train Motors" will be necessary) must be done to put the AutoStar back into normal operational mode once it has become overheated by exposure to the sun. and I wondered if it was relevent. Best regards Richard JudgeMike here: Could have been relevant but he didn't indicate that he had overheated it. But the RESET, CALIBRATE, and TRAIN sequence solved the problem.
Subject: only slew speed Sent: Monday, July 8, 2002 19:36:06 From: email@example.com (neil minihane) I have got a brand new out of the box ETX 125. I have downloaded the most recent software into the autostar. The problem I am having is that there seems to be only one slewing speed available to me. I change the slew speed on the autostar 497 and its the same speed all the time. I cant figure out if its a problem with the scope,autostar or me. I dont think its the scope because the are different speeds available when using the standard hand controller. Maybe I messed up the autostar when I downloaded the 25e program...Thanks a lot if you are able to help with this and thanks for your time...NeilMike here: Does the display show the speed when you attempt to change it? It should. If it doesn't, then perhaps the keypress is not being recognized.
The display changes and shows the different speeds but the speed is the same in each choice...thanks NeilMike here: Is it fast or slow?
Fast only...only one speedMike here: Try a RESET, CALIBRATE, and reTRAIN. When installing an update into the Autostar, it is always necessary to at least reTRAIN. I don't recall a slew speed problem from an update but perhaps the three steps will help. Let me know.
Thanks very much...That did the trick. It was kind of a strange problem and I never saw it referenced in the archives. Thanks again....A big fan...Neil
Subject: Autostar and softwrae control Sent: Friday, July 5, 2002 05:05:39 From: Pieter Kotze This might be a stupid question but do you need the Autostar controller to control an ETX telescope from a computer? Thanks PieterMike here: Yes, you do need the Autostar. The computer sends commands to the Autostar, which controls the telescope.
Is this also true of the larger Meade telescopes like the LX200s etc?Mike here: Don't know exactly how the communication works with those but they include the GOTO computer handcontroller.
Subject: re: Does not want to align Sent: Wednesday, July 3, 2002 21:25:36 From: firstname.lastname@example.org (Richard Seymour) To: email@example.com many of us would be happy to help, but it'd help us if you describe your alignment procedure... and please don't leave stuff out by saying "...per the manual"... It's fairly frequent that folks misinterpret the (ahem) fine manual, and we who have done the same things will recognize it if you state in your own words what you're doing.... so read many of the alignment tips on Mike's site, but feel free to reply with a list of how -you- are doing it. (there's also the chance the scope has a problem) good luck --dick
