1. since i am the owner of an 8'' dob and i am starting astrophotography with an heq5 pro mount do i need this mask for focusing or is it only for SCTs, MACs etc?




I can field the 1st part. The mask will work well with any type of scope. If you have spider vanes, their diffraction spikes will also appear, but are much, much dimmer than the triple diffraction spike pattern and do not interfere.
