You can immediately feel the quality of these, and the solid engineering that went into them.
Full metal housing, coming in at a hefty 125 grams.
Features a 1.25″ long sight tube – for adjusting the secondary mirror tilt and rounding the secondary, and a Cheshire – a tool for adjusting the primary mirror tilt.
As a short tube Cheshire eyepiece that is fitted with cross hairs is simply just too short to be called a sight-tube and has no practical value when aligning the focuser axis of a Newtonian reflector, we stock this superior, long version.
Precision engineered, this device is all you need to collimate your reflector telescope.
