1¼" Filter Holder for T-2 and 2" Filter Threads

Time and again it happens that a 1.25" filter or another part (Barlow lenses, reducers) with a 1¼" filter thread has to be mounted in the path of light of a larger telescope. This is the purpose of this filter holder, which consists of the four components

The Double T-Filterholder accepts common 1¼" filters, as well as, for example, the Q-Barlow lens (please note that this Barlow can only be screwed in about a quarter turn due to technical production characteristics).

When combined with the T-2 Conversion Ring, you get a filter holder that can be screwed between any two T-2 part and has an overall length of 10 mm. In combination with parts with 3 mm long T-2-threads, it sits flush; for parts with 5 mm long threads, a T-2 Fine-Adjustment ring 1mm (gold) – Aluminium #2457913 is also included so that all components sit flush against each other. This allows 1.25" filters or Barlow lenses/reducers with standard 1¼" filter threads to be permanently inserted even in front of accessories that are screwed to the telescope via T-2 threads to prevent them from tilting - be it heavy eyepieces, cameras with filter wheels or an ADC. By installing the filter holder facing one side or the other to the telescope, the distance from filter/barlow to camera/eyepiece can also be changed a little bit.

With the Expanding Ring T-2f / M48m, the adapter can also be used in any 2" filter thread. Although this leads to vignetting on long focal length wide-angle eyepieces, it allows, for example, the use of a 1.25" filter (or a Blaze grating) on 2" eyepieces or on cameras with a fixed 2" filter thread (and a sufficiently small sensor) on which the Baader 1¼" / T-2 plug-in connection with Safety Kerfs # 2458106 cannot be used or if a screw connection to the telescope is preferred.
