The Moon on Apr 29, 2020. Televue TV-85 at F/5.6, QHY183c, UHC-S filter.

M81 & M82 Galaxies, 3hrs on Apr 29, 2020. 180×60 sec, Gain 30, Offset 15, QHY183c at -10C, UHC-S filter, Televue TV-85 at F/5.6.
M12 Globular Cluster on Apr 30, 2020. 70×60 sec, Gain 30, Offset 15, QHY183c at -10C, UHC-S filter, Televue TV-85 at F/5.6.

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.

Comet ATLAS (C/2019 Y4) Disintegration

Comet ATLAS on Apr 14, 2020, 03:42 UT. 20×30 sec, Gain 37, Offset 49, QHY183c at -20C, UHC-S Filter, Televue TV-85 at F/5.6.

Looks like Comet ATLAS was a dud.  It broke up into pieces after it had brightened much higher than predicted last month.  The brightening and breakup so soon afterwards indicates a large release of material from inside the object as it cracked open, so to speak.

By the time I took this pic, there were at least 3 to 5 major pieces in a line and the out-gassing of volatiles available was over with.   Just rock and dust was all that was left.
