TS Optics - 1.25" extension with brass compression ring - 35mm length
... precisely CNC machined

The 1.25" TS extension tube is an ideal problem solver if the focal plane is too far outside. The focuser remains in its optimal position.

Fields of use:
-- straight-through observation with refractors (normally, the standard focusers are not long enough for that)
-- observation with photo-optimized Newtonians having a longer back focus distance

Technical details:

-- precisely CNC machined
-- optical length: 35mm
-- brass compression ring prevents your accessories from dents and scratches
-- with filter thread at the telescope side
