OPTEC PYXIS 3" ROTATOR FOR OFFICINA STELLARE
Optec
OPTEC PYXIS 3" ROTATOR FOR OFFICINA STELLARE is backordered and will ship as soon as it is back in stock.
The Optec Pyxis 3-inch Rotator has a full 3 inches of clear aperture and is designed to hold large instrument packages without flexure or wobble. Package includes adapters for Officina Stellare Pro RC, RiDK and RiFAST telescopes.
A 6-inch bronze worm gear and stainless worm rotate the center tube with a resolution of 0.01875 degree per step from the stepper motor. De-rotation of the field for long exposure images with alt-azimuth mounted telescope and rotation of the guide chip for SBIG camera to a suitable bright guide star are the two primary uses of this instrument.
This model is large and heavy and is intended for larger telescopes on observatory calibre mountings. The 2.4-inch thickness warrants telescopes that can accommodate this increase in the back-focus distance.
