TS-Optics secondary mirror spider with collimation possibility for 16" Newtonian telescopes
A robust spider guarantees good adjustment stability. The TSSPD not only provides safe support for your Newtonian secondary mirror, it also allows its collimation. For this purpose 3x M4 internal threads are provided.

The spider vanes, made of stainless steel, are only 1.5 mm thick. This reduces disturbing diffraction effects around bright stars to a minimum and improves contrast.

This secondary mirror spider is ideal for do-it-yourself construction, but it can also be used with many standard Newton telescopes such as Skywatcher, GSO, Celestron, etc. We also have suitable secondary mirror holders in our assortment (see recommended accessories).

Advantages and features of the TSSPD16 secondary mirror holder:}]
Flexible - suitable for telescope tubes from 448 mm to 460 mm diameter
Counter nuts for the tube are included in the scope of delivery
Suitable for secondary mirror holders from 63 mm diameter at the bottom base
Collimation of the secondary mirror with knurled M4 screws - 3x M4 female threads are present
Diameter of the central part (hub): 58 mm - suitable for secondary mirrors from 63 mm - sufficient clearance for offset is available.
The diameter of the inner hole for the counter screw is 5.5 mm. So secondary mirror holders with M5 internal thread can be used. However, the hole can be drilled out without any problems, for example for M6 or 1/4" screws.
The four spider vanes are fixed with screws. Thus a high tensile load can be built up.

Diameter of the spider:448-460 mm
Height of the central hub and the four vanes:25 mm
Internal thread for collimation:3x M4 female thread
Diameter of the central bore:5.5 mm
Material:Stainless steel - matt black coloured
