Description
The secondary mirror spider is ideally suited for the construction of Newtonian telescopes for observation. The spider is optimized to cause as little obstruction as possible.
The inner part has a diameter of 45 mm and thus allows the use of secondary mirrors from 46 mm diameter in the minor axis.
The spider has an M5 thread on the outside. It is attached to the tube using M5 knurled nuts, which are included in the scope of delivery.
