Solar filters for 15X70 binoculars

[altnacraig]

Does anyone have any recommendations for solar filters for my Celestron 15x70 binoculars. I obviously want to avoid anything that has the risk of falling off - so all ideas welcome.

Thanks

Apart from carefully making your own from Baader planetarium astrosolar film, I can't think of any. Personally I would only consider looking at the Sun through a proper solar scope. All it would take would be a slight cut or hole in the film and you'd run the risk of severe damage to your eyes.

Totally agree with your comments. I've just found online some Orion solar filters to fit 80mm binoculars £134 for the pair!), because I don't want to risk using any form of 'film'. But no luck with anything for 70mm.

Hello! I was curious to know if the filters work well with the 15x70 celestron binoculars? Also, if they do, what all features can you see on the sun?

I bought a thousand oaks solar filter for my William Optics SD66 and this fits over the end of my Celestron 15x70 binos. A bit expensive to buy two of these but I imagine it would work and give you a good view of the Sun.

You probably can construct filters for the 15x70 binocular (but I wouldn't! - too much risk).

A safer method to view the sun might be via projection (put the cap on one of the objective lenses).

Here's a basic example (me showing a partial solar eclipse, outside a pub, back in 1996:drunken_smilie:)

Thanks for the replies. I've decided against filters for binoculars and gone for a solar filter for my Meade ETX125. All I have to do now is wait for the winds to drop and for some sun. Not much of it lately on the Isle of Man!
