Filter Bar for ST7E
The motivation for bulding this accessory was to permit me to use my 2" emission line nebular filters with my ST7E CCD camera when I was imaging through my Takahashi FSQ106 or my Televue TV101.

The idea is to be able to swap filters without removing the camera from the telescope. The FSQ106 has a severe back focus requirement and it is further aggravated when using the Extender Q focal extender. This set the overall thickness at no more than 13/16".
The Takahashi/FSQ/EXQ combo is designed to accept 1.25" nosepieces while the TV101 uses the 2" standard. The design would use interchangeable nosepieces with a common receiver that accepts the filter bar and screws onto the SBIG filter wheel face.
