Excellent shot! Can you give more details? Like what program you used for stacking, how many shots, focal length, etc? I was going to try again last night, but clouds looked to be just enough here to be menacing.
This was on my D750 2 nights ago at between 945-955. I took a series of 200 shots at 4 seconds at 135mm. My lens will only do F5 at that focal length sadly (Tamron 100-400). That's still in twilight which is why the sky isn't black yet and the light pollution from Waco is a light dome on the horizon and you can see it at the bottom of the image.
I loaded all 200 in Deep Sky Stacker and registered them, then removed a certain number of them below a threshold, but I don't remember how many. Safe to say I stacked over half so probably 125-130 of the images. I also did take dark, flat, and bias calibration frames. I didn't know much about this prior to last week and I was intimidated by it but it was actually not too. I used the comet stacking mode with the empahsis on keeping the comet sharp but not the stars.
After that I worked on the image file in Photoshop but its pretty different than normal photo editing. A lot of stretching the histogram and curves adjustments.
Clouds kept my home last night too. Hoping the cirrus off the storms near Houston aren't an issue tonight, but tonight looks great. 2 nights ago the comet was clearly naked eye visible and was pretty huge. Its even higher now, so this is pretty much the sweet spot for good images. I'll start fading faster this week and the moon will also make a return to the evening sky so get out there the next couple of days!
