The deluxe version of model 4317, this
non-rotating helical focuser includes index marks
on the outside of the barrel, which greatly
facilitate focusing when switching between CCD
camera and eyepiece. In addition to visual use,
this focuser also works well for fine focusing of
CCD cameras, digital still cameras and video
cameras. The front attachment is a metric M36.4
P1.0 male thread, or a 1.25" eyepiece interface
when used with adapter 7316 (which includes
threads for 1.25" eyepiece filters). The rear
attachment includes a T-thread for direct
connection to SBIG CCD cameras.
