Dear all, for ZWO ASI1600MM, can I use with it EFW with 36 mm LRGB and narrowband filters, so that if I will buy new camera with larger sensor in future I can use with it effectively too? In general, on what size of filter has influence?
Yes, you can use EFW with 36mm filters with ASI1600MM Pro. Which size of filter is suitable for the camera depends on the focal ratio of your telescope.
