Subject: ETX-70 Autostar Sent: Thursday, May 31, 2007 13:46:36 From: Greg (firstname.lastname@example.org) I just got a Meade ETX-70AT , when I turn it on the bottom line on the hand set moves so fast I can't read it. It's a #494 handset. I can move the scope left, right, up, down and change the speed of movement. I am satified that I can use the scope this way but I would to be abl to use the Autostar functions.I know very little about telescopes and stuff but I have a 3 year old girl and she already wants to know about the night sky. Is there anything that can be done or do I need a new handset? GregMike here: Simple solution to a common question. See the FAQ page for the answer.
Subject: custom 494 autostar movement? is it possible? Sent: Thursday, May 31, 2007 13:10:29 From: Jay Burlage (email@example.com) I see you know a ton about the meade autostar controllers and was wondering if this is possible... First let me give you a little background so that you can understand my application. I do timelapse work and have built a custom camera head based on the DS motors and 494 controller. I love the ten slew speed options and dual axis control for my work. Now I understand that the autostar controllers have 'open architecture' so I'm wondering if I can add even more speed settings and possibly even create 'motion programs' that would do slight acceleration and deceleration curves as well as 'pre programmed' movements? Is this possible or am I dreaming beyond the 'flexibility' of this device? Thanks! Jay Burlage
Subject: Polar Alignment Sent: Wednesday, May 30, 2007 17:38:47 From: Thom Tapp (firstname.lastname@example.org) My ETX-125 alignment works fine in ALT-AZ mode, but when I put the scope in POLAR home position, and do an EASY align, it points down to the North East instead of to the alignment star in almost the opposite position in the sky! I have the mount in home position. I turned it to hard stop (Counter Clockwise) and back so the arm is over the ports and the eyepiece is pointed up as the scope is aimed Celestial North. As I said, ALT-AZ works, but Polar does not. Could I have some setting wrong? I have the TELESCOPE MOUNT setting set to polar, time and date correct, and zip code entered. Any ideas??? Thanks! Thom TappMike here: Could the AutoStar time be 12 hours off (AM vs PM)? Do the other Polar Alignment modes work?

Subject: ASU problem Sent: Thursday, May 24, 2007 05:09:48 From: Massimo Alessandria (firstname.lastname@example.org) I'm italian, so escuse my english ... please! ;) I've read many pages of you site, but i have not find the solution to my problem. I'm trying to update the firmware on my #497, i've the cable and a usb to serial converter, so my COM port is COM16. If i run Hyper Terminal, connect it to handbox and press ctrl+f, autostar response correctly with a "P" ... fine. But if i connect with ASU, it didn't find handbox! I've tried with 4.3, 4.6 and 3.61 version o ASU, but the problem was similar (only 3.61 remember my setting of COM16 port). I've tried in safe mode, in normal mode or in the downloading page of handbox ... nothing! How can i do? Thank you for you help and for your useful site! Massimo AlessandriaMike here: What USB adapter are you using? Not all work reliably with the AutoStar, especially for updating. See the article "AutoStar and USB" on the Helpful Information: AutoStar Info page for more info (I use a Keyspan model and it works fine from Mac OS X). As Dick Seymour has suggested many times, you might try the StarPatch program from http://www.stargps.ca.
Thank you for your fast response. I'va just tried with StarPatch program, but it didn't find COM 16 (only COM4). So i've tried to change the port into .INI file of starpatch,but the program say that was unable to find this port. Now i think that softwares dosn't find my port. Adapter is a "Bandridge": http://tp-bandridge.bandridge.nl/TradePoint/Item_View?itemNo=CPL4211 Thank you ... Massimo AlessandriaMike here: I suspect the driver for that adapter isn't going to work with the AutoStar then. You might want to check into the info in that article I mentioned.
Thank you, i'll try again, or i'll change the adapter. I inform you if something going well.
Subject: re: 497 Handbox on ETX-105PE DIed Sent: Wednesday, May 23, 2007 21:11:39 From: richard seymour (email@example.com) Another thing to try is StarPatch, a non-MEade updater program (which is much more robust about dealing with Windows and COM ports). A free download from http://www.stargps.ca/starpatch.htm You'll need to be in Flash Load for it to operate, given the description of your symptoms. good luck --dick

A number work OK for guiding, but fail at downloading (although mostly it's Belkins which have problems, and they fail -long- before the 42% point). good luck --dick
And an update:
From: Galen Flinn (Galen@macnet.com) Out of the blue I received an email from Richard Seymour advising me of StarPatch. He said I should give the Trial version a try to see if it could reload my Autostar 497. I figured, "What the heck, why not?" I downloaded his program and the appropriate 43EG patch and fired it up. It worked the very first time using my USB-to-RS232 adapter and I am now moving on to recalibrate and train the drives. He had redirected me back to your site to get the right info on setting things up. You guys are great in my book. Thanks a million for tolerating the newbies. Galen...
Subject: 497 Handbox on ETX-105PE DIed Sent: Sunday, May 20, 2007 15:16:30 From: Galen Flinn (Galen@macnet.com) Another newbie here. I just purchased a new ETX-105PE about a month ago. I used it a couple of times to try it out and it seemed to be OK. It Autoaligned fine the first time but when I did a GoTo Saturn it found it but wouldn't track it. I had to constantly keep pressing the arrow keys to have the image stay in the eyepiece when using the 26MM. A couple if nights ago I went out to a different location in my yard to set up on a firm piece of asphalt with a great view. When I tried to Autoalign it kept coming up with just black sky with no bright stars. It appeared to be pointing way off to the right of what I thought should be the star of choice. I went through 9 stars with similar results. I tried to Autoalign several times but no luck. If I slewed the scope to what I thought it was looking for I would get unsuccessful aligns. My next step was to scrub any viewing and go to the Internet to see what I could find. I found out about Training the Drive, so I used a yard light about a mile away and that process seemed to go OK. I then tried using AutoAlign again and had similar results in terms of pointing in the wrong location. This second time I was back at the original viewspot in the backyard. Again, no luck. I then went to the Internet and found that there was new software to update so I downloaded 43eG and began loading into the scope. After about 45 minutes I was still getting a message to not disturb the unit until it was done. Then I fell asleep. When I came back in the morning the batteries were dead in the scope. I replaced them and restarted the scope. The display was blank or would only give random characters. I tried the Safe Mode Flash procedure and it would give me the Flash 3.0 Ready message. I tried downloading in that mode and it would start showing an Initialization message and an escalating percentage number. At around 42% I would get a message saying Data Retrieval Done. When I acknowledged that message by clicking "OK" it would say Initialization Complete... Handbox Restarted. The Handbox display would again be blank. If I tried to communicate at this point all I could get was a message saying the AutoStar software on the PC could not find the scope on any comm port and that was as far as I could go. I tried this procedure several times with the same results. I did the comm port tests and I get back either a "D" or "?" as expected. I tried downloading the Boot ROM Hard Reset I found on your site and I get back the Version message as expected, but nothing happens when I input "I". By the way, I did check the LNT battery and it was sitting at 0.362 volts, so I have replaced that, now. That's not too good for a brand new scope. Is a new Handbox in order, or is there something else I can try? I talked to Meade Customer Support and they said I should go on line and request an RMA. Strange they can't issue one over the phone.I made the request on Friday morning and still haven't heard back from them (Sunday). Galen...Mike here: Were you using a computer with a real serial port or a USB-serial adapter? If a USB adapter, which one? Not all work reliably with the AutoStar. For more on this see the article "AutoStar and USB" on the Helpful Information: AutoStar Info page. I have no problems with the AutoStar using a Keyspan model on my Mac.
I am using a good USB -to-Serial Port adapter. I just bought a new one and it had worked several times with the Autostar. The source for this one says they have had good luck working with several Meade customers on various telescopes. I also have a cheap adapter and it would never talk to the Autostar. I can get it to recognize the handbox in the Safe Mode, but after I start the Autostar update and it retrieves the data, I get a crash the next time I try to talk to it. Galen...Mike here: OK. Are you updating from a file from Meade's site or using a local copy of the file? If trying to update over the Internet, I recommend downloading the file to your hard disk and updating the AutoStar using the local copy. Put the ROM file in the Ephemerides folder.
Subject: Autostar II Conversion Sent: Tuesday, May 15, 2007 20:52:46 From: Fishin (firstname.lastname@example.org) Hi, I am a Meade LX-90 user which can use either a 495 or 497 hand controller, the same as an ETX. I was wondering if you would know, if it is possible to convert the Autostar II controller, to operate the ETX models or the LX-90 models of Meade telescope. Thanks Mike PowellMike here: I haven't heard of anyone doing this. If anyone would have done this it would be Dick Seymour.
From: richard seymour (email@example.com) Quick and easy answer: NO. The Autostar II handbox does -not- contain the autostar itself. The computer/controller is in the -base- of the LX200gps/RCX400 scopes. The handbox is merely a display and keypad, and contains no "smarts" for actually controlling a telescope. have fun --dick
Subject: re: How to Test Autostar rs232 circuits!??? Sent: Tuesday, May 15, 2007 20:50:07 From: richard seymour (firstname.lastname@example.org) Well, i've dug into it... The "Press Press" is a bug in the Autostar firmware (and may have been in there, unreported, since v30Eb) The Autostar is -attempting- to say "Press ENTER", then "Press MODE", etc. but it's displaying the word "ENTER" before writing the word "Press", which proceeds to step on the "ENTER". I've sent a bug report to Meade. As an aside, it -is- actually changing the display when you tap [enter] and [mode], it just looks the same. I must admit that i'm quite puzzled as to why it -works- for N/W/E/W/Up/?/Down have fun, thanks for reporting the quirk --dick
Subject: #494 lit up, flashed some crazy symbols and went blanksponding Sent: Monday, May 14, 2007 17:14:43 From: Mike & Terrie (email@example.com) My son and I were using an old DS-90AT with an Autostar #494 hand controller. I was also using Autostar Suite (Ver 3.23) and while in AS 3.23 I was in the Telescope, Protocol tab, and then into handcontroller. While in the on screen hand controller it began to initialize and then I accidentally unplugged the power to the scope. I plugged the power cord back in and the hand controller lit up as usually at the beginning, flashed some crazy symbols, and went blank. When I unplug the HBX from the scope, the motors go crazy until the power source is unplugged. Is there anyway that I can fix this in layman terms or is it shot and messed up for life. I'd like to fix it. The scope is fine. My son loves it. We were practicing with the Autostar Suite (ver 3.23) with controlling the scope when I decided to see what the on-screen hand controller was. Any & all help is appreciated. They are hard to find on the internet! Even at auctions. Thanks so much. Mike C. & son Springtown TXMike here: You probably corrupted the memory on the AutoStar when power was removed and there is no user-installable update to reload the ROM for the AutoStar #494. You have three alternatives: buy a new (or used) #494, contact Meade for a repair, or buy a #497 (which is user updatable).
Thanks Mike. I greatly appreciate the info. Sincerely, Mike Cook
Subject: How to Test Autostar rs232 circuits!??? Sent: Sunday, May 13, 2007 23:24:04 From: Stephen A Boyd (firstname.lastname@example.org) G'day Michael, I've had a bit of trouble trying to update my autostar and as it kept saying it couldn't find the com port, I tried using your "How to Test Autostar rs232 circuits!" I tried both of my 497s and two different cables and both times with both my autostars they gave me the message "Press Press". I waited and then tried pressing a couple of keys but only got a "bad key" answer. I double checked the short with the paperclip in holes 2 and 3 in the serial plug and still the same message appears. I've shut down both scopes till I hear back from you. Hopefully nothing is too serious....:( Any help would be greatly appreciated.
From our AutoStar expert:
From: Richard Seymour (email@example.com) Which version of firmware? (Meade may have introduced a bug) >> I waited and then tried pressing >> a couple of keys but only got a "bad key" answer. Ah... these people who -stop- after only a couple of keys... Try -each- and -every- key, to see if one of them satisfies it such that it moves on to the next key. At least it -is- noticing your short-circuit, since that's the only way to elicit the "Press" message (although "Press Press" bothers me...) I'm not near my Autostar (for another hour or two) so i cannot test it until later. good luck --dickMike here: That "Press Press" made me wonder too. Maybe a new AutoStar model with a "Press" key instead of "GOTO"; you know, like CapCom says "Press to MECO"...
G'day Dick, AH HA!!!!! got it done....... It's Version 43Eg on both 497s. I just read your answer and went out into the obs and tried again. It came up with "PRESS PRESS" again so I tried pressing 'ENTER' then 'MODE' then 'GOTO'. It wasn't till I hit GOTO that the message changed. The message changed to 'PRESS N' , I did and then it went to 'PRESS S.. then E... then W..... Then went back to "PRESS PRESS" again. I then went through the numbers 1 to 0. The message remained till I hit 0 and then changed to 'PRESS U then ? then D.... then came up with the failure notice you mentioned. I tried both 497s and they both did the same setup...... This is a good thing right? heh heh... Looks like I'm ok on that end, so just have to check the laptop end. I bought a second hand ETX70 a few weeks ago and it's a great little scope with surprisingly good optics. It's noisy as hell but tracks ok. I got the #506 cable set for the 494 handset and it really didn't like it. The handset died but the scope works well with the 497 so will keep it that way. The 494 handset will be rebuilt and become a remote control handset for some bits in the observatory. Question? The serial adapter that came with the #506 cable set.... will it work with the 497 and 505 cable as per the original one? I have two 497s and only one serial plug. Thanks for your help mate and clear skies Stephen

The *entire* 506 is -not- recognized by the 497 Autostar, if/when plugged into the AUX port (or anywhere else). 497's simply don't have the programming required to operate the 506. have fun --dick
Subject: re: Autostar Sent: Tuesday, May 8, 2007 02:04:49 From: Henrik van Holthoon (Henrik.firstname.lastname@example.org) I have LX90GPS as well My experience is as follows; GPS does local time, date and sit coordinates for you, you can check this after alignment by holding MODE about 3 seconds and scroll down to all parameters like RA/decl ,alt/azm and also time ,date and site coordinates. I supose you get the site coordinates measured by the GPS module but I am not sure as I have put in the site coordinates also manually you can do the same by using a handheld GPS or if you own a car GPS or using Google Earth looking up your location. I must say I am disappointed about the goto accuracy in the order of about 3 minutes in both directions. The specs however state 5 minutes goto accuracy so I probably have to live with that. I have cleaned the encoder wheel and sensors from the altitude drive but do not know yet if this makes any difference still bad wheather S France. Regards Henrik
From: richard seymour (email@example.com) Meade has confirmed it's a bug, and shall be fixed in the next release. (i'll see if i can patch it, but no guarantees...) have fun --dick
Subject: Using Two Star Alignment Sent: Sunday, May 6, 2007 07:13:55 From: DennyMarkov@comcast.net (DennyMarkov@comcast.net) I'm wondering if there's a way for me to take advantage of the LNT's auto level, tilt and north but choose my own alignment stars as suggested by the Best Pairs program. I know that I can use the scroll keys to skip to the next alignment star, but this would make for a long, long alignment process if I'm looking for two specific stars. Is there a way to combine the "auto" of the auto-align with the pointing accuracy of the two-star method? Thanks, DennyMike here: Not that I am aware of. Getting to the "manual" alignment process would entail cancelling out of the Auto Alignment after the Leveling-Northing process is completed. But then you would have to mess up both by putting the telesope into a different Home position. Perhaps Dick Seymour can develop a "patch" that would jump to the Two Star alignment code in the AutoStar.
Subject: Autostar Sent: Saturday, May 5, 2007 10:36:37 From: Jan H Kolst (firstname.lastname@example.org) I've just bought an LX 90 8" GPS. When I start Autostar It says: "Getting GPS fix" and after some time "New Site".I thought everything was OK,but it wasn't because the Alignmentstar was rather far from the finderscope though in the right direction.I checked Autostar and it gave me the position of OSLO where the former owner lives and I was in Haugesund which is about 350 miles (500 km) from Oslo. I did a RESET -Calibrate Motors - Traine drives(both axes) - Calibrated Sensors- and manually set SITE Haugesund and the correct coordinates.The Autoalign again.Same procedure as earlier and checked the scope.It told me OSLO and the Oslo coordinates. Perhaps I need to redownload a new version of Autostar? It already has the latest.Any suggestions? Regards Jan H Kolstoe NorwayMike here: I don't have a GPS LX90 so can't comment directly but it sounds like the AutoStar is not getting the current location (and perhaps date/time) from the GPS. I haven't checked a map but depending on the direction between the two sites, the difference may or may not matter. Have you checked the date/time after the GPS fix?
Yes the time and date are both correct after the GPS fix.It is the same date and time in Oslo and Haugesund.
Subject: re: ETX-125AT set-up question Sent: Friday, May 4, 2007 19:56:00 From: richard seymour (email@example.com) First, i'd be highly interested to hear which Time Zone is wrong in the Autostar's database... i feed such bugs to Meade. Second, the time actually doesn't matter much after you've aligned... i'm actually more bothered that the scope doesn't GoTo the original alignment stars very well. (the time does matter for planets and the moon, but for stars the alignment procedure overrules the clock). As Mike alluded to, you can manually change the Time Zone. If you created a Site by entering GPS coordinates, just menu to Setup/Site/Edit/[enter], then scroll up to Setup/Site/Edit/TimeZone. Tap [enter], then change the number to -5.0 for Eastern Time. Tap [enter] to lock it in, then tap [mode] a few times to "come back up" the menu tree. Turn the power off, (count to 5), then On, and enter the time/date and daylight savings (Yes) state. Then see if alignments and GoTos get any better. There are other precursor steps that help alignments. One of the more critical is Setup/Telescope/Train Drives. There's a submenu of "RA" and "DEC", perform those procedures (you can do this in the daytime on a "distant" (100 yards or more) landmark). After that, give the alignment and star-chasing another go... if it still can't GoTo back to the alignment stars, there may be something mechanically loose in the scope. If it's a new scope, consider warranty service (or exchange with the dealer). IF it's a bit older then self-service is certainly feasible... assess if the GoTo's are missing in the Alt or Azimuth directions, and investigate the suspect gear chain (if it's Alt at fault (scope arrives too low), then perhaps there's simply too much grease on the clutch, and opening the fork and cleaning off the excess may cure it). good luck --dick
Subject: ETX-125AT set-up question Sent: Monday, April 30, 2007 19:28:09 From: Rhonda We are having trouble setting up our "go-to" telescope. Since we don't know much about it, we don't know if our issues are operator error (probable) or if we have defective equipment. We bought a Meade ETX-125 AT. When we try to align it, the control panel says we were successful, yet it is unable to find any other stars correctly - it won't even go back to the alignment stars correctly. Our zip code puts us in a Central time zone, although we live in an Eastern time zone. Since we are out in the "country" and not "close to any cities in the database, we used GPS coordinates to set-up our location. We think part of the problem is how we are entering the time. As mentioned. we live in an Eastern time zone, however we are a mile or less from the Central time zone. This issue gives us fits on many items - our satellite receiver, cell phone, etc. - constantly changing from one to another, etc. We have tried to set-up the time in the telescope controller both ways and still can't get it to work. We also were wondering about the daylight savings time issue since it began on a different week time this year. . .Do you have any suggestions or contacts we could use to help us get this thing working? As you can tell, we are getting frustrated! My husband is very good with electronics and all that, so I feel like he is doing everything correctly. It has to be something simple that we are just not thinking of or seeing. Thanks for your time. Any help, suggestions and ideas are very much appreciated! HELP! RhondaMike here: I always recommend using the nearest City Name and not the ZIPCODE. Also, be certain you select the Daylight Saving setting properly for your location. That is a manual selection with the AutoStar so Congress can't be blamed for that problem! You can edit the time zone setting for your location when you edit a site location. If you have not done them, do a CALIBRATE MOTORS and TRAIN DRIVES from the AutoStar menus. As to tips, you might want to read through some of the articles on Alignment Tips on the Helpful Information: AutoStar Info page. If nothing there helps, please describe the exact steps you are doing and what the results are.
