Comet Neowise in between clouds, Jul 23, 2020. It was probably the best night weather wise since Comet Neowise moved to the evening skies, but still too cloudy to bring out my bigger scope. I used a Canon T3 on a tripod with a Sigma 28-70 Zoom for this session.
The top image is stacked with more adaptive noise reduction/rejection and the bottom was a straight additive stack to max out the dimmest parts. All subs were dark and offset calibrated.
Not too bad for being in a Bortle 7 Red Zone and using only an IDAS-LPS filter. But, I need to get to a dark sky location (and some better weather) before this thing passes me by! LoL! Soon, hopefully.
Clear skies, but muggy and lots of muck to shoot through with it that low. It was the clearest morning so far since the comet became visible. That’s a dirt pile in the foreground, btw and not a mountain. LoL!
Below is an image that is a reprocess job on the data with a different color balance, slightly more sub-images and tighter cropping. I also did dark and offset calibration to try and reduce noise.
I was hoping it would come out better than the first one, but since conditions were sub-par to begin with, I guess I will just have to wait until it gets in the evening skies to get a better shot. Oh, well…
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.
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.
