I generally agree with Gus...
My experience is with PST/ PST Mods/ SM60 with various telescopes and blocking filters.
Double stack is perfect for enhancing surface detail but an expensive option.
For narrow field observations, I have to say there’s not much to beat the Daystar Quark.
I have used PST Mods to give cost effective large aperture solar telescopes.
Hope this helps.
