Taken with a Skywatcher ED80 Refractor with a Canon 600D at prime focus. Best 20 of 40 images stacked with Autostakkert 2. No filters used. Average seeing but most frames had light fast moving cloud in them which causes stacking problems due to the varying brightness of each frame. Registax 6 failed to achieve a clean stack due to this I think. Could have easily removed the tinges of false colour but liked it better this way . None of the single frames had any false colour whatsoever so putting this down to seeing and cloud. Going to check the ED80's focuser alignment tomorrow though all the same as haven't checked it for 3-4 years :-) The Lens cell is not collimatable on this scope.
