The Astro Physics 1150GTO is a revamped mid-sized, observatory-grade mount, designed to deliver exceptional performance in a variety of demanding scenarios, ranging from remote, automated imaging setups to star parties where mobility and efficiency are key. With its robust construction and smart engineering, this mount is optimized for both portability and precision.

• Supports up to 125 lbs of equipment, making it suitable for larger imaging systems and complex setups.
• Routes power, USB, and Ethernet cables internally through the RA and Dec axes, which remain detachable for convenient transport.
• A quiet, efficient belt-driven mechanism ensures smooth, reliable slewing and tracking without the noise and backlash of traditional gear drives.
• This system keeps periodic error correction in sync, eliminating the need to reset and preventing drift in the PE curve.
• Operates seamlessly on 12V to 24V DC, perfect for field use with standard batteries or observatory power supplies.
• Continue imaging past the meridian as long as without the need for a meridian flip.
• Fully supported with the latest enhanced ASCOM V2 driver, ensuring broad compatibility with astrophotography software.
• The RA and Dec axes can be easily separated, making transportation and setup manageable for travel or field use.
• Includes built in bubble level.
• This version consists of absolute encoders which boosts tracking accuracy to PE 0.19 and retains memory even if clutches are moved about coordinates.
• Threaded to accept the QHY PoleMaster using the AP900 adapter.

The Astro-Physics GTOCP6 control system integrates the high-precision Renishaw Resolute Absolute Encoder with ultra-quiet brushless micro stepper motors to deliver an observatory-quality mount that’s also quick and easy to set up in the field. It can be operated manually using clutches or electronically, with the encoder loop handling both pointing and tracking.
