Here’s another image of Comet 41P/Tuttle-Giacobini-Kresak taken from a Bortle red zone location which is in the middle of a larger city. No filters and a stock camera on a F/5.6, 480mm focal length telescope were used.
I was able to shoot 2 minute exposures at ISO 400 before it maxed out the light pollution (LP.) This is the StarFreeze version of the data. I have lots more data, too. There is another set of 40x120sec shots and some 90 sec, ISO 400 sub-images I did early on when the comet was lower in the sky and deeper in the LP muck.
For now, this doesn’t look too bad to my eye, considering the conditions. I would estimate the coma is twice the size we see here from a dark-sky location. I’m glad the sky was nearly transparent this night. It made processing easier.
Here’s the obligatory star streaks version:
