Thank you will look into it.
In respect to collimation I found this...part one of three but makes it seem less of a worry...unless the primary is off centre which I picked as as a possibility somewhere in my searching...perhaps need a way to check optical centre..there must be a way...just in case the factory has it off centre...even with this system off centre optics would send you bats. Anyways I will find out how to check.

I have yet to see if the units are still available..must be if not why not and is there a business opportunity...video is seven years old I think.
The interesting thing is this involves projecting concentric circles which was essentially one of my rat bag ideas but I was thinking of a jig to rotate with a beam at various positions and note if it moved..much better to be able to project circle I expect.
