I shot this a week ago in Sedona AZ in the butt crack early hours 😂 of the only night with a clear sky. It was an incredible view and sky. I stacked 9 of the sky frames and 2 of the foreground frames then blended together. Just getting started with Nightscape photography but really enjoying the challenges and finding epic locations to be in and if fortunate enough come away with a few keepers.
Gorgeous image

Thanks very much for the techie info. My interest in the information relates to my Canon version of the lens you used where coma is a problem. Sure I can stop it down but that starts introducing other concerns. Trade-offs are a fact-of-life. My desire to see the download is for the same reason...curious about coma and star shape vs exposure length.
I've only uploaded an image on here a couple times and followed the instructions as given at the bottom of this page. Click on "Choose File", then select the file you want to upload from your browser. You should see the file name next to the "Choose File" button. Click the check box "store original" and then click "Add Attachment". Wait for the image to appear onscreen before clicking "send". I just tried it but the file I selected was >20 MB, which is the size limit.
If you want to capture HA but not modify your camera there are HA filters (clip in or screw on) available at various band widths: e.g 3, 5, 7, 12 nm. Cost is inversely proportional to band width: 3 nm >>> 12 nm. Since you are collecting specific wavelengths of light, less light passes through the filter, which means exposures need to be significantly longer (3 - 5 minute range for a 12 nm filter).
Trackers are great! You can do a lot with one. I started down the astroimaging pathway doing Milky Way photos and was bitten by the deep sky object imaging bug. I've since graduated to a moderate arsenal of 3 trackers, 4 telescopes, 2 mounts, 2 DSLR, 2 cooled astrocams....as it keeps going, the investment keeps building.
Good luck as you continue to probe this type of imaging and keep showing your images here!

Jay thanks for all the information and appreciate the encouragement, obviously you've been at this for a bit. When I get close to pulling the trigger on a tracker I'd love to hear your thoughts on brands and performance.
