Robust and rigid with powerful DC motor featuring Hall encoder for position accuracy and repeatabilty

The usb-nFRAME light-weighted, low profile camera field rotator provides widely-used M54 threads (female) on both telescope and camera ends. The usb-nFRAME adds a mere 25mm to the length to your imaging stack. The high torque 12V DC motor belt drive rotates and smoothhly using Hall position encoders to assure angular accuracy and repeatability to fractions of a degree. Ball bearings and rigid low-friction Acetal/Delrin frame guarantee zero flex.

On the camera side the usb-nFRAME accepts the common M54 thread of many quality field flatteners camera T adapters, T-thread spacers, off-axis guiders, filter wheels, imagers etc.
