Adjusting Skywatcher Equinox focuser tension

All good Crayford focusers (at least those expected to carry any weight) have tension adjustment screws. It is just a matter of locating and applying them. 

The focusers fitted to Skywatcher Equinox telescopes are a good example. Tension is adjusted via a single central hex screw using a 2.5mm hex key. Simply run the focuser in-out while gently turning the key clockwise, it only needs a fraction of a turn. 

A heavy setup like a DSLR camera or CCD camera with filter wheel will require stiffer focuser tension than a regular diagonal and eyepiece.

A little experimentation will soon find the optimum setting. 

Hope that helps :-)
