DESCRIPTION

Officina Stellare 3" RotoFocuser Upgrade for RiDK 300 & RiDK 400

Officina Stellare 3’????????? Digital Rotofocuser Upgrade
for RiDK 300 & 400 Telescopes

The Officina Stellare Rotofocuser offers the finest control of both focusing and field rotation motion when paired with a 300mm or 400mm RiDK telescope. The RotoFocuser was created by coupling a 3’????????? low profile, high precision focuser with a rotator. The heavy duty focuser employs a helical rack-and-pinion type mechanism and offers 25mm of travel (standard version). The rotator and focuser have a slim profile and can easily fit into any optical configuration.

An electronic board performs drive control of two stepping motors, one is dedicated to field rotation, and the other to focuser travel. The board is powered by a 12Vdc power supply and absorbs less than 0.5 Amps with both stepping motors moving. This low power consumption allows the RotoFocuser to be powered by a shared power supply’?????????no need to dedicate a separate battery to the focusing of your telescope!

Both motors allow high precision motion: the focuser’?????????s single step travel is less than 0.1?????m, while the rotator’?????????s single step rotation is less than 1 arc-second. This micro-step driving capability avoids all mechanical vibrations and grants noiseless motions.

The control board of the Officina RotoFocuser features an LCD display and six keys that control the focuser and rotator stepping-motor drivers. The easy-to-use menu is very intuitive. Choose the ?????m height of the focuser and the deg/min/sec position for the rotator, or do a jog-motion of both the focuser and the rotator by pressing two different keys. Other parameters of the LCD display are similarly easy to adjust, such as brightness, contrast, homing, and more.

The interface is a hosting BUS which permits long wired connections (more than 50 meters), which is recommended for professional or amateur observatory installations. With the included ASCOM driver, RotoFocuser control can be achieved by compatible software such as MaximDL or FocusMax.
