UV/IR blocking filter

[vagk]

Hi,

I'm thinking of buying a zwo UV/IR cut filter to use in combination with Baader ND5 astrosolar film. Will it provide extra safety or is it just for astrophotography?

You can have a look at the following thread - they do some really interesting analysis there

Based on that thread, I bought the Baader UV/IR block to be used with the Baader OD5 solar filter. Cataract is not a fun thing to have

I think it also depends on how much you are doing solar observing. If only a few times a year for 10 min seems to me less risk than if an avid solar observer who is glued to the eyepiece all the time
