Manual

Congratulations on your purchase of the Baader FCCT (Filter Changer Camera Tilter). 
It allows the comfortable use of filters on the Celestron RASA 8 with suitable QHY came-
ras, as well as the adjustment of tilt with the camera still attached to the telescope.
This manual will show you how to install and operate it correctly. Please take a few minu-
tes to read it before using the FCCT.
