Description:
The CRM1PT is designed to mount Ø1" (Ø25.4 mm) optics up to 0.37" (9.4 mm) thick in an SM1 threaded rotation carriage. The optic is secured using the included SM1RR retaining ring. For thicker optics, any of our SM1 series of lens tubes can be threaded into the carriage.

The smooth rotation mechanism on the CRM1PT can be manually rotated to any position. When the rotation carriage is locked, the high-precision, backlash-free micrometer can then be used to fine tune the position of the rotation carriage over a range ±7°. The vernier scale provides a resolution of 5 arcmin between consecutive marks. As the mount is rotated across the entire vernier scale, there is a cumulative error of up to ±12.28 arcmin.

The CRM1PT is compatible with the 30 mm cage system and the M4 tapped mounting hole allows the rotation mount to be secured on a post.
