Camera adapter for Takahashi FS-60C and Sky90 to Canon RF mount
Description
This is a Canon RF adapter for small Takahashi refractor telescopes with or without focal reducers. It works on the reducer/flatteners of the FS-60C and the Sky90 which present a M56x0.75 external thread and require a 72mm metal-back distance. It is designed to provide a clear aperture of about 47mm. This is about 9mm wider than a T-thread adapter. Additionally, my adapter with the Baader RF connector weighs 64g compared to 182g for a Tak CA-35 and a Fotasy T2-EOSR adapter. The adapter mates to the D52 ring of a Baader Planetarium Canon RF adapter (Baader part number 2408336 "Baader Wide T Ring for Canon R (Bayonet) with D52i to T-2 and S52"). Also included are STLs for 1mm and 1.5mm spacers that can go between the printed part and the Baader camera adapter to lengthen the metal-back distance a very small amount.
