Pages: 1 dogeddie sage Reged: 03/26/10 Loc: Wisconsin, USA LX 90 LNT defaults to terrestrial targets?       #5630908 - 01/19/13 12:42 AM Edit   Reply   Quote Quick Reply   I am just getting started with the LX 90 LNT I picked up used. I am familiar with Autostar as my old scope was an ETX. When I check the Telescope>Targets area on the Autostar as one means to try to determine the very poor initial star alignment, it appears to be always be set in Terrestrial mode rather than Astronomical mode. I will keep an eye on it, but shouldn't it stay on Astronomical unless I change it? I also had an issue with the time setting - it almost seemed to revert to the previous users time zone, even though I did a reset. Do I have gremlins in my Autostar? I did a calibrate motors, train drives, and calibrate sensors, but the alignment stars were so far off I was unable to tell which one to use until I hit the ? button and it told me the names. Once I managed to align the two stars it was accurate, but I can't figure out why the initial alignment is so bad.

It will automatically set to astronomical at the correct time as you do the align process. One of the bugs in the 497EP is that it doesnt save the LNT calibration data ( or drive train data ) if it falls outside a certain range. Thus, your cal data may actually be lost, thus accounting for the bad initial pointing. You can use my app to interrogate the Hbx to see what the current cal sensor offsets are. That will tell if they are good or not. If not, and you want to keep the 497EP Hbx, you will have to patch Andrew Johansen Melbourne Australia Post Extras:       Pages: 1
