1. So far you have told us nothing that will help us to make any suggestions?
2. What type of mount are you using?
3. What programs are you using to control the scope tracking?
4. Do you use Maxim, The Sky X, or another program?
5. Are you guiding or just tracking, if you are just tracking then your elongated stars which according to you is proportional to your exposure would seem to indicate your polar alignment is not quite what you are led to believe?
6. What method you to do your polar alignment?
7. Do you have T-Point and did you do a T-Point run to verify your Polar Alignment?
8. Did you use a Polar Scope, The Sky X, PemPro, or some other program to help with your Polar Alignment?
9. What kind of Imaging Camera are you using?
10. What kind of guide camera are you using?
11. Do you use a separate guide scope or an OAG?
12. Are you sure your guide camera is par focal with your imaging camera?
13. How are your focusing manually or with FocusMax or other such program?

Hello,
I'm just new to this forum. I've had just one evening to use my new scope, but a couple of issues have come up that I would appreciate any comments on. The weather won't be good for a few more days, so I have some time to consider solutions btwn now and then. Astrophotography is the reason I purchased this scope
Mirror shift, or??? I get increasingly long star trails with increasingly long exposures. How great, if at all, is mirror flop, once locked down? It would be good to know if I can assume this is not an issue, and so can direct my attentions to the other possibilities. My polar alignment is excellent, so is my balance.
Focus. I discovered that focusing is perhaps incredibly easy. Take a dimmish star, move it to the edge of chip and focus it there. Any little bit out of focus quickly and dramatically elongates the star one way or the other. As apposed to focusing in the center where you have to judge more or less bloated. However, focusing this way I noticed that stars midway had red and blue slight comma type flaring. Not good.
And finally, is there a source for a variety of adaptors, that start with the 3.29 16tpi thread. Celstron seems to only offer the large or small T adaptor.
Thanks,
Keith
