The Baader-FlipMirror II Star Diagonal (BFM II) is a very flexible accessory which features three ports.

It can be used straight through (S52, M48 and T-2 threads on both sides). This would be the normal use with a camera (full-frame camera, spectrograph, or other instruments)

There is then an adjustable T-2 thread on top for eyepiece clamps, video modules (up to 32 mm image circle) or even a binoviewer

The bottom flange is intended for the optional Off Axis Guider for Baader FlipMirror II (BFM-OAG) (#2956951), or for an optional calibration lamp for quick calibration of spectra without removing the spectrograph

The precise surface mirrored flip mirror has a multi-layer Alumnimum coating which is suitable for high-resolution images using cameras with small pixels

The back of the flip mirror is also Aluminimum coated and masked to direct the light of an optional calibration lamp onto the slit of a spectrograph

The face of the FlipMirror II has an adjustable plate which enables for the precise adjustment of all light paths

The FlipMirror II is very compact allowing for the shortest possible overall length for any application and is compatible with a large number of T2 and M48 adapters and also Baaders UFC system (Universal Filter Changer)

The rotatable M48 connection rings are made of hardened, stainless steel on front and rear, are backlash-free and adapted to the FlipMirror II housing. They can be fixed in the optimum position to rotate any accessory around the optical axis.

The FlipMirror II is prepared for an optional toothed belt for motorization (e.g. by Steeldrive II motor focuser with Controller (#2957165) ). This is a basic requirement for image acquisition, guiding and spectroscopy in remote observatories.
