TS knurled setting screws for secondary mirrors length 45mm
45mm Standard adjustment screws normally have to be operated by hex Allen keys or screwdrivers. Especially in darkness, this is not very comfortable. The solution: Our knurled screws can be operated directly, even when wearing gloves. They fit to all Newtonian telescopes with M4 secondary adjustment threads (GSO, TS, Skywatcher… ).
