Dennis,
optical system was Megrez 102 - UV/IR filter - QHY8, what I meant by that was, I used Nebulosity 2's focus routine with the mask to get the focus to where the mask said it was perfect, removed the mask, then took 5x45 second subs.. Its a little mini-project Im doing when the neighbors turn their flood lights on, or when the moon ruins clear nights... Photographing the named stars... Anyway, after focusing with the mask using the focus routine then removing the mask and taking the images, I found it was still a little soft..
