In Short:
- ccompact design
- 60 mm aperture, 240 mm focal length
- non rotating helical focuser, lockable
- 1.25" connection with brass compression ring and T2-thread
- Generous back focus from 9 mm to 19 mm from the T2 thread - suitable for all common autoguider
- The helical focuser is attached to the tube by a T2 thread. The distance from the T2 thread on the tube to the focus is 78 mm
- 1.25" eyepieces can also be used, we recommend the TSVF1 to extend the 1.25" barrel
- fits to standard finder shoes - Vixen, Skywatcher, GSO ...

Compact and powerful finder and guide scope
Large aperture, little focal length - guiding stars everywhere, even far away from the Milky Way!
As a finder, the optics offer between 5.3° and 5.8° when combined with our crosshair eyepieces. That´s enough for a good overview. By using eyepieces without reticle, you get a super wide angle telescope for comets and the band of the Milky Way with its star clouds and diffuse nebulae.
Features:
♦ 60 mm aperture, 240 mm focal length, focal ratio f:4
♦ non rotating helical focuser for precise focusing. If optimal sharpness is reached, just tighten the locking screw. The star remains exactly on its position without tilting or shifting.
♦ 1.25" connection with brass compression ring and T2-thread
♦ for using an eyepiece, you need the adapter TST2-1-T2s or the extension tube TSVF1
♦ Standard quick release finder interface (for Vixen, Celestron, Skywatcher, GSO and many others).
Use of autoguiders with 1.25" housing, such as ASI120MINI or Lodestar:
The focus is between 9mm and 19mm behind the 1.25" port. So the sensor would be too far inside. We simply recommend a good 1.25" adapter that screws onto the T2 thread. Suitable adapters are linked. Then the camera can be mounted easily, without focus problems.
Many cameras, like the ZWO MINI Guider, come with a 1.25" extension. With this you can also focus well. The extension should be turned out completely. However, you must not insert the camera completely.
Practical tip from Teleskop-Service:
With the linked eyepiece TSIR20 you only get a sharp image if you first focus the crosshair for your eye, then insert the eyepiece into the TSL60D, but keep a distance of about 4-5 mm, and then focus with the viewfinder/guide scope. To achieve the correct distance, a locking ring is helpful; the 1z counter is linked in the accessory and with a thickness of 5 mm can simply be pushed to the end of the barrel before it is clamped.
