TS Optics 2″ Extension tube – 35mm

Extension tube for 2″ receptacles – 35mm long. This extension tube is the ideal solution if the focal point is too far away from the focuser. In many cases, it also allows the use of a camera with a telescope for photography. This extension bridges 35mm optical path. So the focuser does not have to be screwed out to the hard stop and so the mechanical stability is increased.

In the calculation of the optical length, the 2″ barrel is not taken into account because it sits inside the focuser´s drawtube.

Spec:

• Locking with two knurled screws and brass compression ring
• Solidly CNC machined aluminium
