Rotarion AutoFocus

The perfect AutoFocus device for Rotarion.

Just manually focus one optic or imaging device mounted in any Rotarion port/position, and when selected the rest of optics and imaging devices mounted in the Rotarion are automatically focused!

The Rotarion Remote Control software includes a [T] training key with a proprietary algorithm, so the system calculates for you the variable focus offsets among your telescope and optics, and cameras, so all 4 Rotarion ports/positions become parafocal.

The Rotarion AutoFocus will automatically focus your telescope at any requested distance. Ideal for terrestrial Telescopes too!

Compatible with any DC/stepper motor in the market (JMI, Orion, Tele Vue, Starlight-Feather Touch, Moonlite, etc).
