  • Featherweight Only 3.3 kg for a load capacity of up to 13.5 kg without counterweight (18 kg with).
  • Dual Equatorial and Alt-Azimuthal Mode Flexibility of use for visual observation, planetary and deep-sky imaging.
  • Modern connectivity integrated GPS, Wi-Fi and ASCOM compatibility for quick and easy control via smartphone or PC.
  • Premium Design Sturdy construction in CNC-machined AL6061 aluminum, durable and aesthetically pleasing.

RST-135 vs RST-135E : Comparison chart

Features RST-135 RST-135E (Absolute encoders)
Weight 3.3 kg 3.4 kg
Payload 13.5 kg (without counterweight) 13.5 kg (without counterweight)
Transmission Harmonic Drive Harmonic Drive
Absolute encoders No Yes (RA axis, Renishaw)

Key benefits and differentiation

Harmonic Drive technology virtually eliminates mechanical backlash, resulting in exceptional precision when tracking celestial objects. Unlike traditional geared mounts, it requires no adjustment of mechanical backlash, reducing maintenance to a minimum.

Thanks to its light weight and high load-bearing capacity without counterweight, the RST-135 is ideal for travelling astrophotographers looking for a quick, transportable set-up.

Guiding accuracy

Rated at ± 2.5 arcsec, this mount produces perfectly round stars at any focal length!

Examples

Quick installation and commissioning

  1. Install the mount on your tripod.
  2. Select equatorial or alt-azimuth mode as required.
  3. Use the built-in viewfinder to perform polar alignment.
  4. Activate the built-in GPS to automatically initialize date, time and location.
  5. Start the rapid alignment procedure via the controller or a compatible application.
