These are pictures of Bodes Nebulae M81 that were taken with a Celestron C11 with a hyperstar, guide scope, asimcpro camera, PHD2 for tracking, Siril stacking, and gimp post processing. My gimp skills aren’t that great yet, but improving.
This is the best post processed one I currently have.
So with the hyperstar, I was only able to do around 15-30 second subs. I think because the Focal ratio is reduced so much that the amount of light it is gathering washes out the exposure quicker. If you have any advice on how I can improve, please leave a comment. Thank you.
