What is the purpose of the Baader UFC S70/2" SCT Adapter?
This adapter's primary function is to connect the Baader Universal Filter Changer (UFC) base to a telescope or accessory that has a male 2-inch SCT thread. It features Baader's S70 dovetail on the UFC side and a female 2-inch SCT thread on the accessory side.
Can I use this Baader UFC adapter to attach the UFC directly to my telescope's rear cell?
Yes. Most Schmidt-Cassegrain telescopes have a male 2-inch thread on their rear cell, and this adapter's female 2-inch SCT thread screws directly onto it. It fits an accessory with a male 2-inch SCT thread, such as a focal reducer, the same way.
Is this a telescope-side or camera-side Baader UFC adapter?
It is a telescope-side adapter. It mounts on the telescope-facing side of the UFC base, and its female 2-inch SCT thread connects the filter changer to your telescope or to an accessory with a male 2-inch SCT thread, such as a focal reducer.
What is the S70 dovetail on the Baader UFC adapter for?
The S70 dovetail is Baader's proprietary mounting system for the Universal Filter Changer. It ensures a strong, repeatable, and flex-free connection between the UFC base unit and its various telescope- and camera-side adapters.
How much back focus does the Baader UFC S70/2" adapter use?
While a specific optical length isn't provided in the source data, all Baader UFC components are engineered to be as low-profile as possible. The goal is to minimize the amount of precious back focus consumed within a complex imaging train.
Can I use this adapter with a Celestron f/6.3 reducer on my 8" SCT?
Yes, this is a perfect application. The Celestron f/6.3 reducer has a male 2-inch SCT thread on its camera side. You can place the UFC system after the reducer by using this adapter to connect the UFC base directly to the reducer's output threads before attaching your camera.
