Baader Flip Mirror II - coming soon!

We thought we would just tell you about an exciting new product coming from Baader Planetarium this Summer - their Flip Mirror II (BFM II) as a little more about it, and some new product photos, have been released. We will look at this unit in more detail in another future blog, but for the moment we'll present some of its useful features.

Baader Flip Mirror II

Example set up of BFM II

  • Unlike competing flip mirrors, Baader-FlipMirror II has three ports:
    • Straight-through (M48/T-2 on both sides) port for full-frame camera, spectrograph, or other instruments.
Straight through view
    • A top-mounted T-2-thread for eyepiece holder, video-module (up to 32mm diameter fov) - or even a binocular-viewer!

    • A bottom-port that can accept the optional Baader Off-Axis-Guider prism-assembly (part of the Baader RCC-OAG #2956950) or an optional ThAr-lamp for calibration of spectra.
