Comet 12P Pons-Brooks

[AKB]

Just a brief window before the clouds last night, so took a quick peek to the west and glimpsed the comet.

New scope is still not adjusted for collimation / backfocus / filters / cable diffraction, but as this is something of a transient target, undergoing various outbursts from time to time, I thought it worth a go.

This is with a RASA 11 and an ASI294MC colour camera, but binned x2 in mono, over just five minutes.

Subsequently, I processed them offline in colour, just for a comparison.

I like this mode of working: EEVA is fast and easy with a smaller mono image, but you can return in higher resolution and colour later, if desired.  Best of both worlds!

SharpCap has a live stacking method that aligns on a comet rather than on the stars. I tried it last year and it works well if you want a good view on the night.

This evening, direct from my Seestar, without any post-processing.
