Tuesday night, I was able to get NEOWISE.

Definitely starting to dim at this point, and had to do a fair amount of PP to bring it out, and a lot of background noise; so I decided to try again at a different location with hopefully less background light, and try stacking.

Tried Wednesday night at a rural lake, but proved too cloudy to spot the comet. So I tried to salvage with some wide-sky shots of the clouds using the OM Zuiko 24/2.8 instead of the Nikkor 28/2, and do some stacking.

That seemed to work out all right, so went out Friday night to see if I could get the comet again. Didn't go so well:

Comet was fainter, and stacking didn't seem to help much. I have to wonder if I'd have gotten better results from an ISO 1600 pic without stacking.

Finally, a pic with the MF Rokinon 12mm/f2, which I managed to screw up by assuming that since it was a 'native' mount, 'infinity' would be actual infinity, and not magnify-checking the focus. Oh well. I do think the OOF effect was a little interesting on some of the brighter stars:

Nice. The 1st, 4th  and 5th are my favorites...
