TS-Optics REFRACTOR 0.8x Reducer Corrector for 110 mm f/7 ED - 2" connection
I used this on an
80mm Explore Scientific F6 Triplet
102mm Saxon F7 Triplet
127mm MEAD Triplet
I have the tables from TS-Optics which add / subtract mm depending on the scope size and Focal Length, from 54mm = 62mm
I used 55mm on my SAXON
