Does anyone know of a shorter alternative to the Celestron 48MM T-ADAPTER FOR EDGEHD 9.25”? It is designed to provide the standard 55 mm back focus that so many devices seem to use.
I would like to put a rotator in my imaging train and with my QHY 16200A CFW7 with OAG and M 48 thread adapter, all the 55 mm back focus distance is used.
I know that Precise Parts in the US can probably create something but I thought I would ask.
