1.25" Visual Backs for Unitron, Tasco and Other Japanese .965" Focusers
Replaces the .965" eyepiece visual back on the drawtube of many
Unitron, Tasco and other Japanese scopes that came with .965"
focusers. Allows use of 1.25" eyepieces and accessories while
preserving the in-focus distance so eyepieces will reach focus.
If your .965 visual back unscrews from the focuser drawtube, one
of these should replace it for 1.25" use. Black anodized aluminum
body, single thumb screw.
Measure before ordering! Please measure the male threads on your
factory .965" visual back. You can wrap a strip of paper around
the male threads on your visual back adapter, and mark the paper
where it overlaps. Then lay the paper out flat and measure between
the two marks and divide that by 3.14159265358979323846264338327.
#UTEA has male threads that are 36.25mm or 1.43 inches diameter.
#UTEB has male threads that are 35.50mm or 1.40 inches diameter.
