Baader DT-4 1¼" / 31.8mm nosepiece extension (T-2 part #05)
- Extension tube for 1.25" eyepieces
- Optical path length 31.8mm
- 1¼" filter thread on both sides and can be screwed into almost every 1¼" eyepiece.
- The inner dimensions are prepared for holding the lenses of Baader's glass path correctors 1:1.25 and 1:1.7
There is often a problem with off-axis systems or folding mirror attachments, where the receptacles of normal eyepieces is just 1-2cm too short to be able to adjust the focus properly. This adaptor helps to solve this issue.
