Anti spike mask Newton telescope
You don't want to see any more spikes on your stars on your Newtonian telescope?
Then I have just the thing for you with this anti-spike mask.
This mask refracts the light so that no more visible spikes appear on the stars.
The whole thing is constructed according to this principle:

I need the diameter of the primary mirror and the secondary mirror from you.
Clear Sky, Chris
