Photoshop Version

This is the first time using my new William Optics Zenithstar 81 APO and new guide scope. It took awhile to get my guide camera in focus as it has a very short focal length. Once it was focused thou, I did a rough polar alignment with the polar scope on the mount. I used SharpCap Pro to finetune the alignment. Upon completion, I took a test shot and I could see polaris in the frame. :) What's nice, is the Z81 comes with a built-in Bahtinov mask to focus the Z81 which I really loved using. Once that was completed, I used Carte du Ciel to control my mount as I can click on an object and it will tell the mount to move.

Starless version

I used StarNet++ on the below image and removed all the stars and then apply changes to just the galaxies. Then using Photoshop, I layered the stars back on top, adjusting the opacity.

Combined Starless and Galaxy version

Siril

My first time trying my hand at Siril, stacking and preprocessing. I exported a TIF then continued processing in Photoshop.

Siril

This one I processed completely in SiriL using the tutorial here.
