I’m looking at buying a small refractor for deep sky Astro photography and have my eye on the Sharpstar 61EDPH III (or something similar). I know it’s a relatively new telescope, does anyone have anyone have any experience with it for Astro photography?  Is it a good buy or am I better off going for something like the Askar 71F which looks very promising?

Also, I’m aware that the old version had some issues with chromatic aberration, has this been rectified with this new version?
