Description

WarpAstron WarpDrive WD-20 Harmonic Drive Mount

WD-20 is a High-Load harmonic drive mount based on Servo Direct Drive. It provides standard load capacity up to 50NM without using a counterweight. Most heavy equipments like 130APO, 150APO or C11 can be easily handled by it with ideal guiding performance.

New designed main body with high power density servo motor, significantly boosting load capacity while keeping its weight only 5.4kg.

Both axises have home sensor, which makes astrography more convenient for remote control observatory.

Servo Direct Drive

Servo motor direct driving stain wave reducer, taking advantage of fast response and precise positioning, every mount provides constantly high precision guiding at the same level.

Easy partner

Only weighted 5.4kg supporting both Losmandy & Vixen dovetail, even lighter than most of harmonic mount using Type 17 reducer.

50NM+ High Load Capacity

Load up to 22kg without CW @25cm from RA axis.

High precision encoder

Ensure high precision positioning for servo motor, far exceeding any stepper.

GPS

GPS Beidou positioning module inside, for automatic positioning which easily sync time location to NINA etc. for outdoor operation.

CNC

Mainbody integrally-formed by 5 axises CNC to ensure high strength. Deep Sky Grey Carbon Black anodization
