Baader offers two sizes of T-2 Nosepieces, which allow you to mount your T-2 accessories or Digital Camera into standard 1¼” or 2" focusers or accessories. Both nosepieces have an external T-2 thread on one end, for attaching to T-2 system components. Typical applications include use as the input piece for the Precision Amici Diagonal and OPFA System (afocal and ocular projection).


The latest version of the 2" Nosepiece (T2-16) now incorporates a removable 'stop ring', enabling the nosepiece to slip fully inside 2" barrels for even lower profile or other creative uses.


  • T-2 Photo-Adapter with 2" inner thread
  • Telescope side 2" nose piece barrel with safety groove, focus side T-2 external thread. Effective optical length only 2.5mm.
  • Telescope side has threads for 2" filters (M48 thread).
  • A countersunk T-2 thread for a variety of adaptions such as adapting to T-2 binoviewers


The nosepiece outside diameters are precisely machined and finished to provide a secure fit with a minimum of slop or decentering.  Both nosepieces feature a recessed groove that provides an extra measure of security to prevent accidental slippage.  The 1¼” nosepiece is provided with standard 1¼” filter threads as well as an internal M34 thread for accepting the VIP Barlow Lens or Glasspath Compensators (for Baader/Zeiss Bino-Viewer), and the 2” nosepiece has both 48mm filter threads and a nested internal T-2 thread to enable even more uses within the system.  Of course, both nosepieces incorporate full internal sharp V-threading and blackening to reject stray light and maintain maximum contrast.
