Glend,Alpal, al the simulations you need to see are presented in this thread frpm 2012 on just this topic, with major contributions from all the usual suspects. :-) The end of the thread is probably the most useful.
Regardless I note that the best images on this forum are taken by guys like Rolf, Sidoneo, Fitz Henry, all using known high quality optics. Whether it is because they treat all aspects of the train with equal respect I dont know. I am a visual guy, and I know for sure that everything helps there, and also for the planetary guys doing short exposures .
Glend: you would probably benefit most from upgrading your mount and tracking capability than worrying about the improvemnts of ion milled optics.
