Now being used in the Condor Array Telescope in Chile, a project by Stony Brook University and funded by the National Science Foundation!
NEW design for the QHY 36mm Filter Masks! The improved design is slightly thinner and completely eliminates any possibility of a light leak
These Filter Centering Masks will make it easy to center your filters
in a filter wheel, and will block any potential light leak due to the filters
being off-center in the filter disk seat. Simply place your filter
in the filter wheel disk, place the Filter Centering Mask over the filter
and fasten with screws. Sold in sets of 7, 8 or 9 depending on the
filter mask size.
Available for ZWO, QHY, Atik, QSI, Moravian (GXCCD) and Pegasus Indigo
filter wheels.
Installation note: make sure the two flat sides of the mask point toward the center.
2-3 day Priority shipping available also. International shipping calculated at checkout. Please see the shipping tab for more info.
Printed in durable, temperature tolerant PETG filament.
