Good one, Ken.

I did post one in the July 2020 thread, answer 93 page 7. Your sky is better than mine :), always a bit hazy here.
If the weather forecast is correct, I'll try again on Monday.

It's in my plans but there seem to be nothing but cloudy skies in prospect for the window of opportunity in NW England.  >:(

Wednesday night was quite clear for Seattle, giving excellent viewing.  For these I used the 300 mm f/4 on a small star tracker, allowing me to expose for 20 seconds.  I found that not much was gained going beyond that - the extended tail of the comet showed too little contrast against the light of the city sky.  Against a darker sky I think the tail would nearly fill the frame of the 300 mm, about 8 degrees.
The first photo is lightly processed, the second stretched a bit in Photoshop to roughly equalize the R,G, and B channels in the coma and make the background sky closer to black.
Cheers,  John

Thanks for posting these Brute and beryllium 10!
No dark here yet, and with the comet weakening, I am not sure if dark will catch up in time.

It's been pretty good here in the last couple of days.  I got out last night but didn't do too well owing to inability to get precise focus.  I did a little better tonight by hunting down my old 85/1.8 manual lens, which has a nice hard infinity stop, and is fast enough not to elongate the stars too much.  The D7100 is still a little noisy at night, but at least I can say yes, there was a comet.  Unfortunately, fumbling in the dark with various different ISO settings, I managed to switch it from Raw to JPG, which ticks me off,  but oh well.
