Nicely done  Steve! Did you have to recenter the comet during the 12 minutes?

Thank you. Yes, I think I recentered it two or three times over the 12 minutes.

What I totally miss are the colors. The core is clearly green, even in the individual subs, but during processing I was absolutely not able to realize a color difference between gas tail and dust tail. Maybe the exposure time was too short. I couldn't make use of my Star Adventurer mount as I had to shoot the comet out of my bedroom window without free view on Polaris. That's why 3 seconds were the maximum.

You are dedicated! Out the window! Thanks for sharing the details Steve! I think you nailed the color as difficult as it was.
