About this product
Part Number: 2458055
A telescope can be used with a variety of attachments to cover a range of interests. I.e. an eyepiece, a camera, a spectrometer, etc. But a telescopes has only one port. Changing accessories at night in the dark is not good for the nerves! A flip mirror provides a convenient solution and after using one, you will wonder how you managed without!
The Baader Flip Mirror II is more than a simple flip mirror. Being a Baader product, considerable thought has gone into its design.
1. Straight-through (M48/T-2 on both sides) for full-frame camera, spectrograph, or other instruments
2. Top-mounted T-2-thread for eyepiece holder, video-module (up to 32mm diameter fov) – or even a binocular-viewer
3. Bottom-port prepared to accept the optional Baader Off-Axis-Guider prism-assy (part of RCC-OAG #2956950) or an optional ThAr-lamp for motorised intermittent calibration of spectra
- Precision first surface mirror w. Enhanced-Al coating, for discriminating work w. small pixel cameras
- Backside of flip-mirror is also Al-coated and masked, to direct the light of an optional spectral calibration-lamp onto a spectrograph-slit
- Designed to enable precise adjustment of all optical pathways
- Shortest backfocus for each application – utilizing the wealth of adapters of the Baader Astro T-2 system, M48 system and UFC system
- front and rear M48 rotation-adjustment rings made from hardened stainless steel, matched to the BFM main body for zero play and for rotating and locking the BFM main-body in the optimum rotational alignment with any conceivable accessory equipment
- Readily accepts the Baader Universal Filter Changer system of parts (UFC system)
- Prepared to accept an optional motorised timing belt – as a core-tool for remote imaging, guiding and spectroscopy

It seems that Baader have adopted the SLR mirror system with good effect, so it would seem to make a very simple but effective item. I havenít had the chance to try it on my telescope yet but everything fits to everything else so when I get the next order through I will be able to use it properly. Seems very well made, sturdy useful star diagonal.

I got this to make it easier to align objects in my SkyMax 180 because I was getting very frustrated trying to get some pictures of Mars. The ability to look through an eyepiece to centre an object and then to quickly switch over to the camera is such a timesaver, especially with a very small sensored planetary camera. I will mention that you will need some extra items to connect everything up and add an eyepiece, luckily over the years I've aquired loads of adapters, an adjustable eyepiece focuser is essential so you can get the eyepiece and camera focussed at the same point.
