TPO Truss Tube Ritchey Chretien Reflecting Telescope

This telescope is designed for dedicated enthusiasts and experienced astrophotographers, not beginners. Its 16-inch aperture and complex Ritchey-Chretien optical system require significant experience in collimation, thermal management, and handling heavy, high-precision equipment.

No, this is an optical tube assembly (OTA) only. You will need to purchase a heavy-duty equatorial mount separately that can support the 92.6-pound weight of the tube and your imaging equipment.

The truss tube design reduces the overall weight of the telescope while maintaining structural rigidity, which is essential for keeping the mirrors perfectly aligned. It also allows for better airflow around the optics, helping the telescope reach thermal equilibrium faster.

With a 3250mm focal length and f/8 focal ratio, this instrument is optimized for high-resolution imaging of small, distant deep-sky objects like galaxies and planetary nebulae. It provides the reach needed to capture fine detail, though it requires precise tracking and guiding.

Large mirrors like the one in this 16-inch telescope take a long time to cool down to the ambient temperature of the night air. The integrated fans actively pull air across the mirror surface, preventing heat currents inside the tube that would otherwise blur your images.

The focuser is designed for 2-inch accessories, which are standard for high-end telescopes of this size. You can use 1.25-inch eyepieces, but you will need a 2-inch to 1.25-inch adapter, which is commonly available.
