A variable night. Seeing seemed to improve the later it got. I revisited M101....starting about 11:30pm. I thought I had good focus, but the images are not crisp.....and a lot of light gradient. This has been a difficult target to get right. I will keep coming back to it over the next few days to see if I can improve the data.
I next moved to M13 about 1am. Seeing was improving. M13 is a good test of tracking....no nebulosity....all stars. All of my previous images have been poor, due to tracking issues....oblong and fuzzy stars. * While not DSLR quality, my M13 shots are far and away the best I have been able to achieve. There is hope for me yet.
I packed up my imaging gear at 2am, and then noticed that Jupiter was well up in the South. I hadn't taken a look at it yet this year, so I brought out my son's 6" Dob. To my surprise, the view was fairly crisp. At 200x, I could clearly see the two main cloud bands and some detail in both the northern and southern hemispheres. I couldn't make out any significant detail in the clouds bands.......but there was a crisp, dark round dot, left of center, near the equator.......the shadow of Ganymede.
