So I had a chance to try my 1100HD with the Starlight Xpress H9C. My biggest concern is that I can't seem to take a shot longer than 5 seconds, then the tracking starts to slip bad enough where the stars are oblong and blurred. I am still working on focusing, but I do know the tracking slips. For example, if I will center the M51 galaxy in Nebulosity, and after I take about 20 ten second shots, it will be just outside of the Nebulosity Frame and Focus crosshairs by the end of the shot series. This is seriously messing up my images. I have made sure to correctly balance the scope. Alignment is good, because after it drifts, I will tell it to go to M51 again, and it'll be dead centered. My only thoughts are that I need an autoguider for any shots over 10 seconds and/or the scope is too heavy for the mount and it's slipping. All I have on the mount is the scope, camera, hyperstar, feathertouch/microtouch drive focuser, dewshield, & telrad.
I usually do a 2 star alignment with Arcturus and Dubhe, then Calibrate with Vega and Antares. I need to learn how to do a Polar alignment to make this better. I bought an SXV autoguider, but its backordered so I will just have to wait and see if this fixes the problem.
