Thanks,
Raymo - yes you are right the focuser on the ed80 has started to suffer a bit. either needs serious looking at or upgrading. the weight of the camera actually makes it move 1-2mm even when tightened fully. The rest is because i dont use most a flattener at this stage either.
Kevin: i left the Ir filter in place, just removing the LP2 filter only. most of the stars look fine but the bottom right hand ones definitely bloated for some reason. i was almost going to crop them out. i figure as conitinue to learn more processing techniques i maybe able to tame those couple. Possibly cheat and touch them up with the spot healing or something similar. Im sure theres other ways also. Also as for looking a little purple .. i dont know i kind of like it looking a little on the bluer side of things. when i evened out the blue it looked a lil off to me.. could be my eyes or monitor. i guess as i get better at these things everything has to change too
with working long hours ive been limited in imaging runs.. so i was glad to see after all set and done.. the mod i did works and everything focuses corectly as it should.
