Set of M4 Screws for Easy Secondary Mirror Adjustment - fits GSO, Skywatcher Newton & Dobson telescopes and many more.
Who does not know the tedious fiddling with allen wrench or screwdriver, when it comes to the collimation of the secondary mirror. We have a solution from TS.
These thumbscrews fit into any GSO, Skywatcher, TS and many other Newtonian telescopes (e.g. Celestron Nexstar 130 SLT) with M4 (D = 4 mm) adjustment screws. This is a TS Upgrade Kit for easy secondary mirror adjustment without tools: three thumbscrews with 45mm length of thread - the thread is consistent - so that you can freely determine the position of the secondary mirror.

The tip of the thumb screws is milled - it has no burr thus high pressure points on the secondary mirror are avoided and an undesired rotation of the secondary mirror during adjustment is prevented.

The knurled head of the screw is made ​​of plastic. It only has a diameter of 12mm, so that it can be used with a small secondary mirror without the knurled head protruding into the beam path.
