Hello,
I am looking to use my original PST telescope tube with a crayford focuser. For everything to remain square I need an adapter. A pre made adapter would be greatly appreciated.

Re: [WANTED] Crayford focuser to PST etalon adapter
Trent,
I think RustyVenture is selling the adaptors...
The rear thread on the PST etalon is M50 x 1, and the SCT thread 2" x 24tpi.
With a couple of wraps of plumbers tape on the PST thread it's possible to get a good fit without an additional adaptor.
Hope this helps.

Hi all,
I am still after one of these adapters, as the plumbing tape doesn't guarantee a square fit I have come to find out.
