Hey Bill,
Sorry I took so long to reply, I haven't been on the forum in a while. I am curious, how may subs did you stack to create this image? As far as Seestar goes, it's amazing what it can do for $500 but stacking a few short exposures will result in a noisy final image.
First, I would attempt only the brightest objects. In addition, you will want to take as many exposures as possible until field rotation becomes a limiting factor. Try your best to center objects allowing you to continue to take more exposures. In the end, the more subs you can stack together the better your final image will be. You can also try shorter exposure times and increase your exposure count. When you start with better data it will be that much easier to process both in the linear and non-linear state
Remember Garbage in = Garbage out.
Start with the cleanest data that you can collect. You can get good images from the Seestar, you just need to coax them out.
I've seen a lot of impressive images from club members who have used the Seestar. Since I don't own one, I can only guess what should work. Reach out to someone who has successfully produced images with data collected using a Seestar.
Good luck,
