Helical Focuser with T-threads and 1.25" Eyepiece Holder
Our new helical focuser has features imagers love! Most important,
the camera or eyepiece doesn't spin when you focus. Male T-threads
on one end and Female T-threads on the other end to include the
focuser in imaging setups. For 1.25" eyepieces or cameras, a self-
centering twist-lock adapter fits on the male T-threads. Great for
guide camera or eyepiece focusing with off-axis guiders.
Overall height is less than 1.5" so it doesn't eat up precious focus
path distance. Minimum height with male T-threads exposed is 1.38".
Minimum height with the 1.25" twist-lock is 1.49". Focus travel is
0.2" in two turns of the rubber grip control ring.
Inside diameter is 1.25", overall outside diameter is 2.25". A locking
thumbscrew is included to aid in installation and removal.
