Comet C-2022 E3 (ZTF) 22 Jan 2023

 

First attempt at capturing and editing a comet.

Lot's of new processes to learn and to experiment with.

 

This was a tricky one for me to process. I eventually ended up with creating a full integration of the star tracked sequence which after initial processing, I removed the stars for the starfield and discarded the residue comet.

I ran a batch Star Xterminate on all the calibrated, debayered and star aligned subframes. These starless subframes were then comet aligned in PixInsight and image integrated using the first frame as the reference frame.

The starless comet was processed separately from the star image and eventually recombined using a Pixelmath combine expression.

Looking forward to the next opportunity to capture more frames in a new position in the sky and hopefully a better result.
