diy Baader solar filter for 8" Dob - Full aperture/quarter?
Hope i'm posting in the right forum
I bought an A4 size Baader AstroSolar film off Ebay to make a solar filter for my 8" Dob, I've done my search on the subject and I've seen different pictures of people only using a quarter of their aperture, but there are products for 8" SCT that filters the whole 8"'s worth.
The big question is what would I expect from (or should I even consider) a full aperture filter compared to just a opening a quarter (á la the duct tape filter on sidewalk astronomer's website) or even something in between?
cheers!
