These 3D-printed filter holders for the Baader FCCT make swapping out filters quick and painless. With built-in neodymium magnets, the filter holders are always held in the same position and cannot accidentally fall out.

Available in three different sizes: 47.4mm (2" unmounted), 31mm and 36mm. Compatible only with the Baader FCCT and Celestron RASA 8".

The Baader FCCT Filter Changer and Tilter is an all-in-one filter drawer system for the Celestron RASA 8" and QHY cameras. The integrated tilting mechanism allows quick and painless adjustment of the field in order to get perfect stars edge to edge.

As the RASA 8" has extremely limited backfocus, only some QHY cameras can be used. Additionally, the FCCT is only compatible with unmounted filters. Two different assemblies are available depending on what which camera you would like to connect:

  • FCCT I - QHY cameras with 77mm diameter - 174, 163, 183
  • FCCT II - QHY cameras with 90mm diameter - 268 (MONO only), 294, 533

Due to the small amount of backfocus of the RASA 8", regular mounted 1.25" and 2" filters cannot be used. For the larger 11" and 36cm RASA models which have more backfocus available, we recommend the Baader UFC system instead.

 

 

 

Only the RASA 8 has the image plane is so close to the Schmidt plate that the original front adjustment screws cannot be reached as soon as a camera is connected. To remedy this shortcoming, the FCCT can accommodate specially designed, 3D-printed thin filter drawers and, in addition, precisely align the chip plane within fractions of a millimetre by means of easily accessible adjustment screws positioned 120° apart at the side of the filter chamber. This makes working with the RASA 8 a pleasure, without having to fight for a perfect image position for a long time.
