GSO Main Mirror Holder for DIY construction of Newtonian telescopes

The holder is ideal for Newtonian primary mirrors from Guan-Sheng-Optics (Taiwan). Also matching are all other Newtonian primaries with a diameter of 153 mm or sligthly less.

Practical tip from Teleskop Service - installation with adjustment option

Requirement for correct installation is an inner tube diameter of more than 176 mm. If the tube is smaller, you cannot sink the primary mirror holder into the tube.

Make a ring (wood or aluminium) which fits perfectly ito your telescope tube. Mounting is done just with lateral screws.

Bore three 6.5 mm holes with exactly 81.5 mm distance from the center, placed at 120° to each other. The three M6 adjustment screws go through them.

For keeping the main mirror in the desired position, you need a thrust spring. Suggestion: item number TSFeder (set of 3 pieces)

As adjustment screws, you can use standard hardware store products, but we offer M6 adjustment screws, too.
