Is there a ZWO or aftermarket IR-UV Cut window for ASI183MC Pro? I would like to install one permanently on the camera so I can use other filters on my EFW with it.
or where we could get the original ones?
Get yourself this one: diameter 31 mm, unmounted: https://www.baader-planetarium.com/en/baader-uvir-cut--l-filter.html
It will reportedly fit nicely instead of the clear window that has a diameter of 32 mm.
