Description

In this photography I applied black velour on the spider.

The spikes decreased a lot, but a lot of light is added around the stars.

I think I prefer the spikes.

I never expected that in a 20 "f3 Newtonian telescope the spikes could almost completely disappear, because the spider is thick to rigidly support the diagonal mirror.
