Baader 3" SteelTrack Focuser
This focuser will fit to any Newtonian Optical tube with a 3" fitting, it is designed for professional use and has a 40mm back focus with high weight bearing capacity, making it a good choice if you wish to add extra accessories to your scope.
The Focuser is coated with Titanium Oxide to make a rock hard, extremely durable, quality product with a exceptional feel and movement.
There is a vernier scale engraved onto the focuser with an estimated 1mm accuracy, and the focuser also uses a reflex free, 5mm inner baffle to keep the movement as accurate as possible.
Please note that the Titanium coatings do vary in colour slightly as they are stress relieved prior to machining and this can vary the colour of the finished product.
