Subject: My LXD-75 not Align!!! Sent: Wednesday, January 18, 2006 04:48:07 From: V V (email@example.com) Has it ever occur to you when you make Calibration and Train motors and afterwards when you go for Align it goes in stars elsewhere and elsewhere!!! The steps that I followed are below: 1. Reset (from menu of Autostar) 2. calibration motors 3. Train drive (RA and DEC) 4. Right hour and + 2 for my site 5. Daylight saves NO for Winter 6. Lat and Log rightly for the place that I am 7. Power off and turn it On. 8. The displey now (0 or MODE for Align) It searching and give a (eg.) Rigel it going but exceed very much (Dec axis collides with the body of RA motor)!!! The Train drive has been made with 12mm eyepiece at 2km nevertheless not only it does not go there that the star is supposed roughly to be but the motor of Dec axis collides with the body of RA motor. I tried again to put the last version in my Auto Star, I had used the same version when I had the old head, then he sent me the new head without however to change the remote control and it presented the same problems. I have telescope but I does not have driving. If any of you has mount with Autostar #497 and has faced similar problem I would be grateful if he could help me!!! My Telescope is LXD-75 8" SC, and version of software autostar is 40Ef I try 10 times the procedure of train drive but the problem it remains!!! I thought of using other publication of software (older) Or try to reset the autostar in to mother version and then to put the new!!! Friendly & sory for my bad English!!! George TarsoudisMike here: Instead of doing the Easy Two Star Alignment, try a One Star Alignment. Follow the prompts on the Autostar display. Let me know what happens.
I try tonight (afetr 2 hour for my town) to do this!!! First I try to Align with 2 strars because yesterday I have doing Train and after I turn OFF telescope. If doesnt work again I try one star Align!!! Thanks again for yours times !!!
The last night I tried with the One star aligment but the problem doesnt untied. I send one photo with the problem . After the failed procedure of one star Align I try to hard reset my autostar with Entet button & down key and I put again the last version autostar 40ef. I try now in day to procedure of Train drive after of this procedure what can I do? Turn off my autostar ? During the night wish procedure do you advice me to follow? My Autostar belongs to my previous head wich had another problem. And now when I start the procedure of Align the Autostar eg. searhing the Rigel but it cant recognize the star although the telescope passes in front of it. A one question more, Exists case this version 40 ef it creates problem. Try to put the older version. And if yes from where him I lower? But the 40ef version in my old Head work rightly. My lat : 40 57.931' N and Log : 25 54.392' E (Alexandoupoli, Greece) and my time zone is +2 hours, the daylight saveings is NO or Yes for Winter? but this is not very much problem because is +1 or -1 hour. Thanks Mr Mike for your times again. Friendly George TarsoudisMike here: Older versions of the Autostar software is on the Autostar Archive in the Helpful Information: Autostar Info page. So you can try that if you want to. But one other comment since you haven't mentioned it; have you selected the proper telescope model and mounting mode in the Autostar? OH WAIT A MINUTE!!!! I think I see the problem from the photo you sent. The DEC drive should be on the West side of the mount, not the East side. At least, that is true on the LXD55 model. Remove the OTA, swing the DEC axis 180 degrees and reattach the OTA.

This is the rigth position on LXD-75 model , the picture that I sent is from the handbook of LXD-75. Have Mr Mike experience with the 40ef version the last version of autostar. Because perhaps this is the problem, I do not know what other problem exists . Have you Mr Mike table or Schematic diagram of train drive after I put a new version of autostar . When finished the update I turn off the autostar, now at night what I do fisrt. Can put the target first to terestial objects and after the train I put it to the astronomical targets. And after finish the Train drive can close the ON-OFF switch. And when I put new version can do RESET and Calibration motors options and finaly go for train drive? Thanks again Mr Weasner.Mike here: I haven't yet installed 4.0Ef so can't comment on that. As to CALIBRATE MOTORS and TRAIN DRIVES, if I understand what you are asking, they should be retained following a power off.
Subject: LXD55 versis LXD75 trypod Sent: Wednesday, January 4, 2006 21:43:46 From: Harold Ogden (firstname.lastname@example.org) I have a LXD75 SN8 ordered but Meade cannot deliver for at least 4 more weeks it has been 7 weeks so far my question is 75 trypod that much better than the 55? I assume everything else is the same. I have the opertunity of getting new 55 without wateing shoud I wate? HaroldMike here: I think the wait will be worth it.
Subject: LXD75-SC8 Microfocuser Sent: Tuesday, January 3, 2006 10:57:41 From: Dave Wallace (email@example.com) Does anybody have experience with the Meade microfocuser? And which model is the right one for the SC-8? I find that even with a Hartmann mask I have trouble hitting correct focus while trying to do astrophotography because the scope vibrates somewhat when I manually focus. (My set-up consists of the LXD75-SC8, the Meade T-adapter and a Canon Digital Rebel DSLR camera. I'm a relative newbie to astrophotography.)Mike here: I don't recall seeing any comments on it. How do you like the LXD75 mount?
The mount works very well for me (now that the RA drive issue has been corrected). Tracking is pretty good, the mount is up to the task for the SC-8 and its vibrational characteristics are excellent. I'm still trying to calibrate the polar alignment scope, though. It's close enough for visual work but a 30-second or longer exposure will show that the Autostar has to jog the DEC drive every so often while following the sky. I've not yet tried enabling PEC; I figure I might as well wait until the polar scope is properly aligned. No point in correcting minor RA errors when I still have major DEC corrections.
