As discussed here I lowered the diameter of my APO by adding a diaphragm in front, in order to increase the F/D of my setup and get better contrast (at the cost of less definition) with my Daystar Quark, while conserving the same scale to keep having the full disc in my sensor. It works quite well!
APO 70mm f/7.5 (original 102mm f/5.2) + UV/IR-cut filter + telecentric 3x + Daystar Quark combo + Zwo 2600mm
Full disk 10/08/22 with Quark and a tweak
