EFW filter clearance?

Postby MartinF » Tue Nov 28, 2017 1:35 pm

I´ve just bought the EFW 8-pos and a ZWO LRGB + narrowband 31mm filter set. However, I also have a (very expensive, that´s why I want to use it) Astrodon 3nm Ha-filter, 1.25". The stated clearance for the EFW is "less than 7 mm" but my Astrodon filter seems to be a bit above 7 mm, maybe 7.5 or so.
Will this be OK? It would be a shame if one couldn´t use filters from other manufacturers, especially when there is a need for 3nm Ha-filters.
