Tried on several clear, sunny days and nothing yet. Please advise.Tue, 08 Dec 2009 22:48:25 GMThttp://www.fixya.com/support/t711731-40mm_solarmax_filterI have an original Coronado 40mm Solarmax filter set. I don't know the BF size. Based on the price I paid, it sounds like a 5mm. When I ordered I told them It would be used on a Celestron C5. How can I determine the BF size?Tue, 08 Dec 2009 22:48:25 GMT
