This is a 12 pane mosaic taken with the 100mm pst mod, alot of effort to do as at its native focal length of f10 sweetspotting and vignetting is apparent, taking alot od work in post processing to remove. Compare with the full disk in the post below, and I think I will be carrying on using the DS40 for my full disks; despite the DS40 only having 40% the aperture of the larger scope, the extra detail the tighter bandwidth delivers far outweighs the resolution the 100mm offers.
