Comet C/2022 E3 (ZFT) circa 05:15 / 20-01-2023

Set the alarm for this one.

Comprises 29x 60 second subs with an Altair 102 Ascent ED refractor, ASI585MC camera (gain 253) Baader MPCC MkIII coma corrector and Baader UV/IR cut filter on an iOptron CEM60 EQ mount.

Subs were guided on the star background and the comet alignment done later in PI. The nucleus is mow quite bright and caused some problems with its removal from the stars only  (good as StarXTerminator is it couldn't remove the comets coma for the stars only image).

I saved the stars plus coma image as a tiff file and transported that into PS where I used the colour range selection tool to gradually fill selections with background colour until I had a selection of the whole background minus stars filled with the background colour.

Back in PI I added some saturation to the star colour and added the comet and stars together with pixelmath.

Added single sub with streaker....

I hope you like

Awesome capture! I'm waiting for it close in on Polaris and become an evening object. It should be in good position and magnitude at perigee!
