Comet C/2012 K5 Linear on 1-7-13. Moving through Taurus. This is 4.5 hours of travel time. Some high clouds rolled is near the end.

You may want to pick the 1080 HD quality in the bottom right corner

Thank you AdirondackAstro for bringing the comet to my attention

That is really cool. I didn't realize it moved so fast.

I was surprised at it's speed too. I was originally going to take 120 second subs, but it was trailing noticeably. I'd like to get a good image but I'm having trouble stacking it is DSS. I'll keep working on it.

I finally got a half decent comet stack with DSS. It seemed to be best to only use 10 lights. I then registered them with a 2% star detection threshold. I then selected the comet in each frame. Stacked with Comet + Stars, then stacked with Kappa-Sigma clipping. DSS also had a couple minute "Not Responding" perion between the star stack and comet stacking phase.

I tried that too. With over 10 I get diagonal noise and gradient rings in the comet.
