Which filters are compatible, and which set should I choose?
Choose the set that matches your unmounted Baader filters: 4x 31mm or 4x 36mm for round filters with a thickness of 2mm, or 4x 2" for 2-inch filters with a glass diameter of 47.4 mm. None of the sets are compatible with filters that are pre-mounted in threaded cells.
How many holders come in one FCCT Filter Holder set?
This product includes a set of four individual filter holders, allowing you to populate a filter drawer for LRGB, narrowband, or other filter combinations.
What prevents the FCCT filter holders from falling out of the drawer?
Each holder has built-in Neodymium magnets. These create a secure connection with the filter drawer, holding it firmly in place and ensuring it cannot fall out accidentally during use.
Can I use threaded, mounted filters with these FCCT holders?
No. These holders are specifically made for unmounted filter glass of 31mm, 36mm or 47.4 mm diameter. The outer metal cell of a mounted filter, such as a standard M48-threaded 2" filter, will not fit inside these holders.
As these FCCT holders are 3D-printed, how durable are they?
The holders are printed from a durable, high-quality material designed for astronomical accessories. While they are robust enough for regular use, they should be handled with care compared to machined aluminum parts. The lightweight nature of the 3D-printed material helps reduce the overall weight on your imaging train.
Will these holders work with my Baader FCCT II system?
These holders are designed for the Baader FCCT system. You should confirm compatibility with your specific version of the FCCT (I or II) and its corresponding filter drawer, as designs can vary. These are made for drawers that accept this specific magnetic, unmounted filter holder format.
