James,
Compare your image of IC 443 with mine that I took last night with my Celestron Origin. (Images from AMN at CRO 22 Nov).
While your session was double or triple the time that mine was, I was at CRO, and you’d think the image from a scope that costs 8x more than your Seestar would at least get an image as good as yours. But I like yours better!
Maybe I should have kept the Seestar and sold my Origin!
