I added more data so this now has 98X L - Mostly 60sec subs and 17 RGB again min

Think this version is a little less garish!

Very nice. What scope/camera did you use?

Stars are elongated along one diagonal. Can that be a mismatched flattener to sensor distance issue?

Yeah I know I have a spacing problem, I bought some deer in rings but its a nightmare to sort due to only getting 1 clear night a month!  So I add 0.5mm then wait a month, then add another 0.5mm ......  How do I know if I will be able to get it correct?  It’s the Altair ed70 scope and matching 1.x flattener.
