I'm not real experienced at imaging comets.  Trying to capture the diverging comet path against the backdrop of stars is a challenge.  I decided to go with short 15 second subs.  But there was still the problem of the comet moving through the frame, so I chose only ten subs.  So this is my simple compromise.  Any easy solutions?

Very nice, you could try using the comet feature in AstroPixelProcessor, that will stack the comet separate from the stars.

Thanks!  And I like this idea, it sounds like an elegant solution, especially since I'm already using APP.  I just need a little nudge sometimes to push myself to learn more of it's features.

I am still needing to do research on how to access APP's comet feature.   When I get a bit more time, I will delve into some how-to videos.  It doesn't look simple, unless I'm missing something.

Meanwhile, here is a single frame ISO 3200 shot processed with Photoshop...

Nice shot.

I would like to give it a try when it is visible on our side of the equator.
How are you photograph it?

Did you use sidereal tracking and guiding?

Thanks for your encouraging comments. I almost didn't go out that morning. It was cold (29f) and windy. But I pushed myself and I'm glad I did. A couple things helped; 1) it was quite clear. 2) nice and dark, Bortle 3. 3) the scope is 8 inches aperture, f/4, which has decent light gathering capacity. I would really like to see what the larger scopes are seeing!
