Comet C2017 K2 (PanSTARRS)

[Yawning Angel]

My first proper try at a colour comet image, and what a trial!

Stacked for the background stars, then pulled the stars out with StarXTerminator. Then ran CometAlignment on all of the subs, and integrated the RG & B comet files with some aggressive rejection to clear up most of the start trails.
Cleaned up the mono subs backgrounds. Combined into a colour image, then XTerminated some noise and sorted the colour balance
Curves adjustments to taste then layered the stars back in

Not 100% happy, as it still showing some diagonal artefacts from the stars but it's getting there. Hoping for a few more stabs at it 🤞

APM 107/700 + asi1600mm. 20 x 2min each in RG&B. Processed in PixInsight then Photoshop

Great capture 

It was a lot simpler when we used film 😆 

Is this Comet about Mag 7 ? I may try to get a photo when the moon eases off.

Thank you!

Yes, it’s around mag 7. Hopefully tomorrow it well placed with M10 for some interest. Finger crossed 🤞

Managed to get it passing M10 on the 15th  not yet 100% happy with the processing, which is proving tricky 😁
