The QHY fiter wheels have a dovetail stage instead of threads. If you
remove the camera from the filter wheel the filters and interior of the
filter wheel are exposed. I designed dust caps that clamp into either of
the QHY dovetail stages using the existing screws.
Dust-QHYFW50 fits the QHYCFW3-S, QHYCFW3-M, QHYCFW3-L, QHYCFW2-S and QHYCFW2-M filter wheel 50.8mm stage.
Dust-QHYFW77 fits the QHYCFW3-XL fitler wheel 77mm stage.
