No flattener mate this is straight optics. Most images are cropped as I take them over several weekends (months even some time) and LRGB misalignment necessitates cropping. I am pretty vision impaired so I will blame it on that - I know its an undesirable handicap for a astrophotographer but it adds to the challenge. Im dreading my next licence test - I can see big stuff like cars, galaxies etc just the smaller stuff escapes me. Detached retinas from 25 years of rugby league - gotta love the game.
Roland sure knows his stuff. My only comment is that the focuser is so good - when focusing with DL once I get close to the lowest 1/2FD I just grab the focuser and think about turning it in the required direction and that can drop it nearly a pixel. It just snaps into focus - which is good but I tend to find myself chasing seeing when focusing and a little tweak can increase 1/2fd by several pixels.
