  • SCT to 2" Adapter

    The SCT - 2" Adapter creates a simple, robust connection between two common astronomy standards. It features male SCT (2") threads on one end and a male 2" barrel on the other, allowing you to mount accessories like focal reducers directly into a 2" focuser or visual back. For added utility, the interior of the 2" barrel is threaded to accept standard 48mm filters.

    Bridging SCT Accessories and 2" Focusers

    This adapter solves a common connection problem for imagers and visual observers. If you have an accessory with female SCT threads but a telescope with a 2" focuser, this component provides the necessary mechanical bridge. The 2" barrel slides into your focuser just like an eyepiece, while the male SCT threads securely attach to your accessory. The internal 48mm filter threads give you a convenient place to install a light pollution or nebula filter, positioning it at the front of your optical train.

  • What is the primary purpose of this SCT - 2" Adapter?

    This adapter is designed to attach an accessory that has female SCT threads (such as many focal reducers or off-axis guiders) to a telescope focuser or visual back that accepts a 2" barrel.

    Can I use this SCT - 2" Adapter to put my SCT focal reducer on a refractor with a 2" focuser?

    Yes, this is a perfect application for this adapter. It allows you to use accessories designed for the SCT thread standard on other telescope systems, provided they have a 2" focuser to insert the adapter's barrel into.

    Where do filters go when using the SCT - 2" Adapter?

    The inside of the adapter's 2" barrel is threaded to accept standard 48mm (2") filters. This places the filter inside your focuser's drawtube, in front of the SCT-threaded accessory you have attached.
