Barry is still doing stuff at Beacon Hill (just spoken to him on the phone). He's excellent at making stuff to order. I have had his 14" dob since 1991 and it's given years of good service, but I now have an Orion Optics 20" which doesn't however allow quite enough latitude in focussing as I would like. Barry Watts is basically making an extension drawtube for me (in fact he guessed everything I wanted before I told him). I can certainly confirm that OO's optics are truly excellent and John's engineering is a thing of beauty in its design and especially accuracy. Collimation of my new scope involved tweaking ONLY the 3 main mirror screws and took about 5 minutes, possibly less!
