TS-Optics adapter from internal thread T2 to M28, i.e. 1.25" filter thread

The TS T2i-M28i adapter with a length of only 10 mm allows short adaptation of eyepieces to the T2 external thread.

♦ Connection on the telescope side: Internal thread T2 (M42x0.75) - extended or easily accessible

♦ Eyepiece side connection: M28x0.6 female thread - 1.25" filter thread is also used on some eyepieces to connect the receptacle

♦ 10mm overall length saves valuable optical path

♦ The second image shows the use of the adapter between ORIR12 and the TSOAG27 (eyepiece, illuminator and Off Axis Guider not included)

TS-Optics adapter with T2 female thread and M28 female thread (1.25" filter thread)

Short special solution for connecting eyepieces with filter thread to T2

Many 1.25" eyepieces have an M28x0.6 male thread (1/4" filter thread) when the silver barrel is unscrewed. The TS Adapter T2i-M28i with a total length of only 10 mm allows a short connection to the T2 external thread - save up to 20 mm!

Application areas:

The adapter makes sense where it is important to adapt the eyepieces to the T2 as rigidly and quickly as possible.

♦ Extremely short adaptation of cross-shaped eyepieces to the T2 connection of off-axis guides

♦ Adaptation of the focusing eyepieces to the T2 thread: fine adjustment is made by means of the variable T2 extension rings. With this you can build very good calibration eyepieces for spotting scopes and telephoto lenses.

♦ Basic adapter for finderscopes for off-axis guidance when using automatic guides

How do I determine if my eyepiece is suitable for the adapter?

Simply unscrew the 1.25" silver barrel, turn it over, and try screwing the barrel into the eyepiece. If that works, your eyepiece barrel has the proper thread.

Which eyepieces offered by TS are suitable:

♦ TS Super Plössl eyepieces up to 25mm focal length

♦ ORIR12: 12mm reticle eyepiece, illuminated or non-illuminated

Connection on telescope side: T2 (M42x0.75) internal thread
Connection on eyepiece side: M28x0.6 internal thread (1.25" filter thread)
Optical path length: 10 mm
