Baader RT-Adapter Diamond Steeltrack for Synta/Celestron Refractors - Ø97mm

You must physically remove your stock focuser and measure the inner diameter of the optical tube. This adapter is machined to fit the specific dimension listed in the product title (Ø97mm). This is the only way to guarantee compatibility.

No. Compatibility is based solely on the inner tube diameter matching the dimension specified in this product's title. Many different tube sizes exist across various models and production years, so physical measurement is the only way to confirm a fit.

This adapter is designed exclusively to mount a Baader Planetarium Diamond Steeltrack (BDS-RT) Refractor Focuser. It is not compatible with other Baader focusers or focusers from other brands.

It is not possible to confirm fitment based on the telescope model alone, as specifications can change. You must measure the inner diameter of your optical tube to see if it matches the required dimension for this specific RT-Adapter before ordering.

To know if this is the correct adapter, you must first confirm your telescope's inner tube diameter matches the specification in the product title. If it does, using this adapter to mount a Diamond Steeltrack focuser will provide a much more stable and precise platform for carrying a camera and filter wheel, which is essential for deep-sky imaging of targets like M42.

Its sole purpose is to provide a solid mechanical connection between a Baader Diamond Steeltrack focuser and the main tube of a refractor. This allows you to replace a lower-quality stock focuser with a high-precision Baader unit, improving performance for both visual observation and astrophotography.
