C/2017 K2 (PANSTARRS) 2022-Aug-21 Dan Bartlett

Switched it up a bit using a 250mm RedCat51 (51mm objective) hoping to achieve a wider field with tight stars. I also flipped the field to have a better resemblance of the "blue horsehead". 30 x 120 seconds at F/5 is a little slow for my taste and the smoke from a wild fire played havoc on the gradients as well as influencing a brownish hue to the image.
