Baader AstroSolar Safety Film 20x30cm, Telescope Qual. ND = 5.0

AstroSolar Safety Film 20x30cm, Telescope Quality, ND = 5.0

This is the filter material that's being used in all Celestron ready-made filters.
If the filter size you are after has been discontinued, we would recommend to buy one of these and make your own filter by using some cardboard or plastic sheet.
The most important about making your own solar filter is to make sure that it cannot occasionally fall from your telescope whilst observing the Sun. E.g. secure it with a cellotape or velcro...

If the 20x30cm film is not big enough for your telescope, there are bigger sizes available HERE...

Never use any eyepiece filter for solar observation without objective front filter!
