Just a day before the major Aurora event, I was shooting Bode & Cigar IFN. Well, because there is nothing much to shoot up in here around this time of the year! Then realized I can see the Milky Way around NE at 2 am, then decided to look what's up there. Well, there was the comet. Would it worth trying? Then the background looked good to my eye and decided to give it a shot. Although I'm in B4-5, our North is very dark. There is a small town then there is nothing for more than 100 miles. I can even say there is nothing until you go around the North pole. And this is the result of that 1h40m integration. I have to admit, it took an entire day to process this image taken with a mono camera. I failed so many times, but eventually I'm glad I decided to give it a shot that night.

I can imagine it took some work to process this image. Came out really nice.

Did you use comet tracking? I see that you used 3 min exposures (for LRGB).

Nice work!

Thank you!

Thanks! No I did not use comet tracking. You are right though, it moves significantly in 3 mins. But that wasn't a planned shot. At that moment I quickly checked similar images and 3 mins seemed ok. Since there isn't much detail on the tail, it didn't become an issue. Also I'm quite undersampling, the core looked fine on a single image. But shorter would have been better.
