I imaged the galaxy above and the globular below on Sunday, May 10, 2020. Very nice weather that day and a pretty good evening, too. Being I had to work the next day, I cut the session short and only got data on two objects.
M13 Globula Cluster. 100×30 sec, Gain 42 and 1hr (60×60 sec) at Gain 30, Offset 31, QHY183c at -10C, UHC-S filter, Televue TV-85 at F/5.6.
M63, the Sunflower Galaxy. 121×60 sec @ Gain 30, Offset 15, QHY183c at -10C, UHC-S filter, Televue TV-85 at F/5.6M5 Globular Cluster.. 172×60 sec @ Gain 30, Offset 15, QHY183c at -10C, UHC-S filter, Televue TV-85 at F/5.6M27 Planetary Nebula. 60×60 sec @ Gain 30, Offset 15, QHY183c at -10C, UHC-S filter, Televue TV-85 at F/5.6
The Sunflower Galaxy was the second time this year for imaging it, so I combined the two data sets and got this detail view below. It is 3.77 hrs total time:

These are all the objects I managed to image on the night of Wednesday, April 29, 2020 and on into Thursday morning. SharpCap 3.2 LiveStacking with dark and flat calibration plus dithering was used for acquisition. Only minimal processing for all of these captures in Fitsworks and PS CS3.
I was trying not to waste a very clear evening after a storm had moved through earlier that day. Not too bad, I guess.

Cut short by clouds! I have been wanting to get this object, too. It was finally in an area of the sky and there at the right time for me to get at least 90 minutes worth of time on it. But, the clouds came in and ruined things only half-way in. What I did get was decent, at least.
M101 on Feb 29, 2020 UT. 206×30 sec, Gain37, Offset 15, 116×60 sec, Gain 20, Offset 15, QHY183c at -20C, UHC-S filter, Televue TV-85 at F/5.6.
Two sets of data taken back to back. First set was with 30 sec, high-gain sub-images and the 2nd set was with 60 sec subs at medium gain. Total time was 3.65 hours. Cropped about 50% out to isolate the galaxy. The 60 sec subs were better, but only because I had centered the target better and it was higher in the sky when I started the set.

This image is still in process. It was not the best night for attempting this since transparency was poor at the time of imaging it. Lots of LP in the 4 hrs of exposure accumulated and almost overwhelmed the dim galaxies. The color was zapped out, so I took an image with only about 2 hrs of time and used it as color and the 4 hrs of exposure was used as luminosity.
