Yep, out of focus
Grab a bahtinov mask from
Bintel to fit your scope.
Also, for DSO's....more subs and take flats and darks. Try 1 to 5 minute subs and stack those. Get your polar alignment as spot on as you can, as well.
Planetary and lunar pics....grab yourself a
modded webcam or a DMK21, a filter wheel and some filters from Bintel. Much better than a DSLR camera for that type of work.
