Quote:I am in the north hemisphere. 10 degrees north.Uncle rod I used the ASPA, that's how I have been finding my targets better. I did my first calibration and used ASPA and got things aligned using positioning and latitude. Its the drift that remains, I have a theory that once I tighten the polar alignment the drift will lessen. I may try again tonight if the weather and schedule permits.While I know not to expect objects to be dead center always, for AP I will need to get it close as possible.This has been a convoluted thread, but it seems i am getting there, no?
Quote:ah! I have seen the mount but I heard that it did. If I were to go over to celestron I would tell them," Oye, stamp arrows in all your mounts, put dew shields as part of the basic ota package and while you are at it, fire the people who made the alt az knobs....try fine tuning the mount with those for a while, lets see your fingers after that, Celestron execs!"I like Celestron but I am not above tell them when they are foolish.I will pat them on the head though...the Advanced GT is a nice system to work with.
Quote:Ok. So last night I set out to solve the drift issue. Set up the mount within the triangle. Sighted my stars and made sure I got my calib stars and did aspa. Mount was level and everything. My goto still sent my targets either lower right or to the bottom. In thr case of m67, piece of the cluster is outside of the 25mm. Those if you who so ap, is this common? Also do you just use the direction buttons to center it?The drift was notably less. I moved the head in alt az a little. I hope this lessens the drift. The drift is south to north.
Quote:ah ok, thank you. For AP proposes, moving the image to he center after goto had found it should keep it in view? I am asking this in the assumption i have done rough drift alignment.The VX looks good, but I can't really afford another mount right now.
