Re: Prism Diagonal

I collimated my new refractor yesterday with the chesire. So far, so good... But when I put my new 2" burgess prism in it and did another check I saw that the instrument was now heavyly out of collimation. When I put a lasercollimator in the prism only I saw that the reflection on the other side of the prism diagonal was 8mm out of the center... :-s.
I don't think it's possible to collimate this prism diagonal. Is this normal? Should I ask a new one from the dealer?
First I'd double check the diagonal's collimation with your Cheshire.
It took a few spoonfulls of aggravation and a cupfull of cuss words, but I managed to collimate an old Orion prism diagonal of mine. But in your case if you bought it new I'd call for a replacement, or let them collimate it and return it.
