Would like to locate a T-ring adapter with a 43mm outside thread. Scopetronics' part number would be STR43T, but any brand will do.
This is the ring that would be used to screw onto a MaxView 40 and allow various cameras witha 43mm filter thread to screw onto the adapter. (This would be used typically along with the CLA-1 adapter tube, which I already have. The scopetronics number for both pieces as a kit is STAK3)
