ROTARION The Eyepiece Wheel

Automatically quickly and accurately switch between eyepieces and other optics.

The AstronSCIENTIFIC’s ROTARION Eyepiece Wheel is a universal and automatic eyepiece exchanger. You can automatically quick-change eyepieces and any other optics. The eyepiece change is easy, fast, and accurate, without touching the telescope, and therefore avoiding disturbances or deviations in the positioning of the optical axis of the telescope.

ROTARION is a device of the highest quality, designed and manufactured in Barcelona, Spain with state-of-the-art techniques and the best materials and components from the US,  Japan and Germany.

Designed for daytime terrestrial observation and for nighttime astronomical observation its a unique device, patented in the European Union and the United States, to be used with any telescope with a 2" focuser and four of your favourite 1.25" eyepieces.

You can change the power or magnification of your telescope with just a simple click, connecting your ROTARION remotely to a Windows computer with the ROTARION REMOTE CONTROL software included in this box. No more searching in the dark for your next eyepiece! The automatic eyepiece change allows you to adjust the correct magnification on your telescope by increasing or decreasing the focal length of the eyepiece used, the "zoom effect"and re-locate lost objects out of the field of view due to improper alignment or poor tracking of the telescope. Quick change to your largest eyepiece in mm number to maximise visual field and re-locate. All with a simple Click!

Combine with other ROTARION accessories such as the handset to make eyepiece changes even easier or, for more advanced usage add the Photo or AutoFocus accessories to enable eyepiece projection through different eyepieces with automatic focusing. For expert amateurs or professions you can even combine with the Camera kit to attach multiple cameras enabling the remote control and switching of multiple pieces of instrumentation locally or even remotely.
