Thanks, that seems ideal. I will ask about becoming a member and hopefully get my telescope checked as well.
I shone a powerful torch down my telescope and took a photo with a digicam.

My laser collimator indicates the above setup is fine, although visually it appears wrong. If I line up everything according to my Cheshire then I have to wind the primary mirror's adjustment bolts a _long_ way one way (two very tight, one very loose) and everything is centered. But put the laser back in (which is collimated) and alignment is way off (about 2cm on the primary mirror).
