Good day everyone))) While outside, Cyclone Barbara is bringing order, rain is pouring and the wind is howling, I have once again re-stacked and reprocessed the material on the "Squid" Nebula. This time following all the rules and with all calibration frames. That's it, I can't do any better for now, enough is enough, I need to catch a comet.

I also considered using my 200mm lens, but when I saw how much oxygen came out (only the Squid Nebula fit in the frame) in a single 10-minute exposure, I immediately gave up on that idea. Plus, I didn’t have much shooting time left. I’ll try again when I speed up to F3.75.
But again, only the Squid Nebula will fit. So I need to shoot with the Askar FRA500 with a 0.75 reducer, but that will be F4.2.

Great photos. Could you tell me how you manage the shutter speed on your Nikon? I have a D3400 and I can't get it to work with APT or NINA for exposures longer than 30 seconds!
