for MQR III&IV, Witty 1 & V bracket #2457010.
The finder shoe provides the connection between the finder bracket and the
6×30 and 8×50 finder and the telescope tube. The finder shoe from
Baader is particularly high-quality processed and offers through
Longitudinal holes a mounting option on almost all telescopes,
among other things also at Schmidt Cassegrains or also at devices, where
simpler viewfinders used to be attached.
