1" diameter Filter Clearance on EFW1 filter wheel

[swVAastro]

Hi,

What is the maximum filter thickness that would clear  in an EFW1 carousel ?

Thanks

Sorry, the filters are 1.25" diameter not 1" diameter

Hello,

We haven't made the EFW1 for quite a few years now, from what I remember the clearance is around 6 of 7 mm. Most makes of astronomy filters will fit.

Best regards
