How to make a solar filter for an 8" dob?
Hi all,
I recently bought some Baader solar filter sheet and I was hoping to be able to make a simple/easy solar filter out of it this weekend. I have an 8" dob and the filter that I bought is probably not quite that wide - It's an A4 sheet so I'd say it's good for 6" (at least) or up to 7".
What the easiest/safest/cheapest way to do so?
