Some random astro-photography

[LookingForScope]

The sky was super clear around 1am to 2am on the 23rd of June so I did a bit of star gazing that turned into an improtu photog session on a random tiny "cluster"? (please correct me on the technical term!) Unfortunately focus wasnt perfect but still better than nothing I guess.

One question though, how do I remove the green colour in the middle of the image? I am using gimp and I remove undesired colours by substracting layers. Any other ways to do it or tips are very much welcome! Hoping for more clear skies soon!!

You may want to try the free tool of Siril, although the image looks quite OK to me.

if you use Pixinsight, a process SCNR in NoiseReduction can remove the green in your image.
