Finally, an opportunity to do some imaging. The conditions were not ideal...some light haze, but considering the poor weather in June, it was pretty good.
After getting a late start, I had some problems getting back into gear. It took me too long to get the scope aligned, and centered on my target. Naturally the camera then refused to respond to Nebulosity.......that took another 1/2 hour of fiddling to get that to work right. Then I was 11 frames into the sequence before I realized I hadn't fine focused. So, I stopped, re-focused, and started again. Considering these issues, I decided not to attempt getting my guide camera working....and thus limited my exposures to 60 seconds.
