2" EXTENSION, LENGTH 35 mm

Features:

• Locking with two knurled screws and brass compression ring
• Solidly CNC machined aluminium
• 2" filter thread at the telescope side
• No savety groove - no tilting - perfect for brass compression clambing

An extension tube is the ideal solution if the focal point is too far away from the focuser. In many cases, it allows the photographic use of a telescope. This extension bridges 35 mm optical path. So the focuser does not have to be screwed out to the hard stop and 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.
