Re: Lock screw for 1:10 focuser on 66 SD apo
- I use a stellarvue 2" camera adapter. This device consists of
actually two pieces. If you unscrew the 2" chrome tube from the
black T-threaded thingy, it reveals an SCT thread (2"-24 tpi). So
using the chrome tube, screw in the .63 focal reducer, then screw
the black thingy onto the FR, then screw the assembly into your
camera's T-adapter for a prime focus hookup......

neat " SCT to 2" adapter from Scope-Stuff that will allow me to use
the supplied SCT 2" diagonal mirror with my other refractors. My
Canon 10D comes to focus with a 11/4 adapter-but barely. Has anyone
usedthe SCT-2" adapter for prime focus?
