Popular Post Dmack1 Posted April 20, 2021 Popular Post Share Posted April 20, 2021 (edited) Having read that some of the newer FF/FR's do a reasonable job with older SCT's I decided to give the old 8" LX200 a try with my SW 80ED 0.85 reducer/flattener - my thinking was that it could not be any worse than the coma I get from my 0.63 Meade 4000 FF/FR. I stuck the ASI2600mc on it not really expecting much but this is what I got.... 8" LX200 GPS on a wedge, SW 0.85 FF/FR, ASI 2600mc, 120 x 120s Bin 2 x2 Now this is a bit of a crop but only really for edges and framing but the fact is that the really ugly U-shaped stars which, on the 0.65s start half way out and are horrendous by the corners, are largely gone. Who'd have thought! Still a little bit mis-shaped out at the corners but I think another mm or so on backspace will sort that. At 0.85 the LX200 should be coming in at 1700mm FL but platesolving is calling it 1976mm ?? I binned this 2x2 in camera but have since read that with the ASI2600mc the recommendation is not to Bin in camera but rather do it in processing. Would anyone have any advice on that and how/when to do it in APP/PI C & C appreciated. Edited April 20, 2021 by Dmack1 12 Quote Link to comment Share on other sites More sharing options...
