Celestron SCT to 2" Visual Back

Celestron SCT to 2” Adapter – Unlock 2” Accessory Compatibility for Your Cassegrain Telescope

Expand the versatility of your telescope with the Celestron SCT to 2” Adapter, a high-quality, precision-engineered accessory that lets you use a wide range of 2” diagonals, eyepieces, and astroimaging gear with your Schmidt-Cassegrain or Maksutov-Cassegrain telescope. If you want to take full advantage of your telescope’s light-gathering capabilities or attach a camera for deep-sky astrophotography, this adapter is an essential upgrade.

Seamless Connection to 2” Visual Accessories

Standard Cassegrain telescopes often come with a visual back that only accommodates 1.25” accessories. This SCT to 2” adapter opens the door to larger-format 2” accessories, including:

• 2” star diagonals for wider fields of view

• 2” eyepieces for immersive visual observing

• T-adapters and camera gear for astrophotography setups

With this adapter, you can maximise light throughput and enjoy brighter, wider views—especially useful for observing faint deep-sky objects or capturing long-exposure images with your camera.

Ultra-Secure Threaded Fit with Non-Marring Compression Ring

The adapter threads directly onto the rear cell of your Schmidt-Cassegrain or Maksutov-Cassegrain telescope, ensuring a solid and wobble-free connection. On the opposite end, it features a brass compression ring—a secure and user-friendly mechanism that grips your 2” accessories without scratching or denting the barrel.

Just tighten the convenient set screw to gently compress the ring around your accessory, keeping it firmly in place with excellent optical alignment.

Durable Construction with Light-Suppressing Interior

Built to withstand years of use in the field, the adapter is crafted from precision-machined aluminium and finished with a black anodised coating for long-lasting corrosion resistance. Internally, the adapter is glare-threaded and painted flat black to suppress unwanted light reflections—enhancing contrast and image clarity at the eyepiece or camera sensor.

Key Features:

• Allows use of standard 2” diagonals, eyepieces, and camera accessories with SCT and Maksutov-Cassegrain telescopes

• Threads securely onto SCT/Mak telescope rear cells

• Brass compression ring prevents damage to accessory barrels

• Set screw ensures tight and stable connection

• Constructed from CNC-machined anodised aluminium for strength and durability

• Flat-black, glare-reducing interior for improved image contrast

• Ideal for both visual astronomy and astrophotography
