Comet 41P on Mar 31, 2017, 02:46 UT. Comet 114×120 @ ISO 400, stars 72×120 sec @ ISO 400, TV-85 at F/5.6, Canon T3

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:
