Pegasus Astro – Falcon Rotator is a light-weighted, low profile camera field rotator. Do not be fooled by its thin size! It can lift and handle heavy image trains – dead accurate! Very easy to operate via ASCOM drivers or standalone software will make your life easier to automatically adjust with precision your camera field.
Low profile / M54 threaded
Thickness of the rotator is 18mm / 0.7”.
When you use the M54 to M48 adapter the backfocus is +1mm (18+1 = 19mm)
Weight is 700grams. Both openings of the rotator are M54 threaded (pitch 0.75mm)
Adapters for both sides (included)
We provide two different adapters for both sides:
- Telescope Side: M54 male to 2” Nosepiece (1.5mm thickness)
- Camera Side: M54 Male to M48 Male Adapter (2.0mm thickness)

The M54 adapter black ring on the camera side of the Falcon Rotator sticks out by almost 1mm (so actual back-focus is 18+1 =19mm)
Backfocus drawing can be found below (click for enlarge):
If you use the nosepiece and the M54 adapter this sums a 22.5mm of backfocus
(Nosepiece is 1.5mm + 19mm rotator + 2mm M54 Male to M48 Male)
A powerful geared / low backlash stepper motor ensures that the rotator will lock to the designated degrees. Mechanics inside the focuser guarantee zero flex in any point during a full circle rotation.
Falcon Rotator has been tested at 6Kg / 13.2lbs of imaging setup.
The 6 stainless steel branded bearings can easily handle higher payloads with zero flexure.
Cable Wrap Prevention
Rotator does not allow a clockwise turn above 220 degrees. It will turn anti-clickwise when it has to be moved above 220 degrees. A nice cable wrap/snag prevention feature out of the box.
Optional adapters available
De-Rotation support for Alt/Az mounts
Rotator has the mechanical precision to achieve field de-rotation. Supplied software calculates Rate of Rotation (RoR) based on the site latitude, target altitude and azimuth position.

ASCOM & INDI Support
Rotator fully supports latest ASCOM 6.5.
INDI is also supported via latest (currently nightly build) of INDI
Control the Falcon Rotator from the supplied standalone Windows software.
