Hi,
My scope itself is well collimated. The Orion diag. that I have shows the whole scope mirror through a cheshire sight tube and shows good cllimation. The problem is that the Orion diag. mirror is in very poor condition.
The Intes diag. that I have has a beautiful mirror but doesn't show the whole scope mirror through the cheshire site tube. It shows like a very gibbous moon.

The fact that the Orion works well and has shown the best images that I have seen and a very nice star test (rotten mirror and poor seeing and all)tells me that the Intes Diag. Might be off.
My question is would a collimatable Diag take care of this problem?
Thanx and clear skies
