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.
M67 Open Cluster on Feb 22, 2020. 50×30 sec @ Gain 37, Offset 15, QHY183c cooled to -20C, UHC-S filter, TV-85 at F/5.6, SharpCap 3.2 LiveStacking with Dither.
A quickie of M67. Marginal conditions with seeing and only average transparancy. But, you have to take what you can get in February. Hopefully, we’ll get more than just one or two nights of good skies in March.
M13 on Feb 2, 2020. 100×30 sec, Gain 42, Offset 15, -20C, QHY183c, UHC-S filter, TV-85 at F/5.6.
Last object of my imaging session for the night of Feb 1st/2nd, 2020 was the globular cluster, M13. Twilight was just starting when I stopped at 100 sub-images. Not too bad for a quickie.

Here is an image of a comet that is big and bright enough to make some interesting images, especially when it passes near objects like the Double Cluster. I missed the closest approach of these two due to weather and other factors, but at least I got the parting shot of them together.

I was surprised how well this came out with only about an hour of data. I was after galaxies this night and I only took this to kill time. Even the 33 minutes worth I posted initially looked half-decent. I will have to devote a session to this one and possibly use the L-eNhance filter instead of the UHC-S.
