I want to get this solar filter for my telescope. It's the Solar Filter for Observer 60 Altaz & EQ model. It was made for the Observer, but I was wondering if it would work on my Celestron 60 AZ Model (refractor)? The guide at the bottom says what model it fits, and obviously, only Orions are listed. So I just wanted to double-check as I don't want to order the filter and have it shipped to me, then find out it doesn't fit. I've been told it should fit perfectly though.
