A robust spider ensures high adjustment stability. Not only provides safe support for your Newtonian secondary mirror, but also allows its collimation.
The spider vanes, made of stainless steel, are only 0.5 mm thick. This reduces annoying diffraction effects around bright stars to a minimum and improves contrast.
This secondary mirror spider is perfect for self-construction, but it can also be used for commercially available Newtonian telescopes, for example from Skywatcher, GSO, Celestron, etc. We also offer matching secondary mirror holders (see recommended accessories).
Parts included:
- 4 spider vanes (EE055 / EE056 / EE057)
- 1 central hub
- 3 front screws (front of hub) (CC036)
- 1 long front screws (front of hub) (CC013)
- 8 small screws for attaching vane to hub (CC033)
- 4 fixing screws for adding thread to vane (FF233)
- 4 small screws for attaching fixing screw to vane (CC034)
- 1 large silver screw for attaching fixing screw to OTA (FF111 or FF240)
- 1 spring for attaching between hub and secondary mirror holder (NN001 / NN006)
