Baader 2" Visual Back with Integrated Filter Holder for SC Telescopes

    Baader 2" Deluxe SC Visual Back with M48 Filter Holder for enabling connection to any Schmidt-Cassegrain telescope via either 2" or M58 thread
  • Facilitates the permanent attachment of 2" filters to the rear cell of most SCTs
  • Keeps dust from accumulating on the inside of your SCT optical tube through the inclusion of any Baader 2” filter (UV/IR cut)
  • The use of non-Baader filters with larger outer diameters may lead to problems
  • An optional 3.3" adapter makes this accessory suitable for use with C11 and C14 Schmidt-Cassegrains as well

In addition to the two parts that make up the base version of the 2" Visual Back, a 2" eyepiece clamp and factory-mounted inner thread ring for downsizing the innate telescope sided inner thread from M58 to 2", this SC Deluxe version also contains an M48 filter holder. Threading this filter holder onto the 2" telescope thread allows any Baader 2" filter to be accepted.

The combination of these parts, when threaded onto any SC telescope, resembles Baader's common 2" Deluxe clamp, but offers much better performance than any available 2" SC clamp. Now you can seal your optical tube from dust and dirt with a clear filter, or add a UV-IR filter to cut infrared transmissions. And if you are up for a night of deep-sky observing, why not install a nebula filter beforehand and not have to worry about uninstalling and re-installing the filter with every change of the eyepiece?

The important distinction between Baader 2" filters and other 2" filters is that the former are optically polished as to not destroy or impair the wavefront of light and to retain perfect sharpness even under high magnification.

What makes the Baader visual back system so special? It is the ability to install a filter between the rear cell and your visual back. Now you can seal your optical tube from dust and dirt with a clear filter, or add a UV-IR filter to cut infrared transmissions. And if you are up for a night of deep-sky observing, why not install a nebula filter beforehand and not have to worry about uninstalling and re-installing the filter with every change of the eyepiece?

The Baader 2" eyepiece clamp has a bronze clamping ring and two thumbscrews for a secure fit of your 2" diagonal or other accessories.
