Gave my William Optics Zenithstar 80ED II telescope a spin recently using my full frame Nikon Z6 with the WO Adjustable Field Flattner IV. I purchased this Apochromatic Refractor used several years ago for about $250 and made several upgrades for it to be astrophotography worthy although as the video points out, there are some hiccups still to work out.
