Charlie, I remember one night when you were setting up the big dob that your dog licked the mirror. That might have also compromised the views that night. I don't know if it was the same night Chuck referred to.

The views that night were probably suffering from poor optical alignment. The scope needed improvement. For the past decade I have been experimenting with a open truss design. From the first massive Dob I learned the importance of good mirror support, keeping the total weight down while maintaining columination and portability. But, with time restraints such as family, job and several other astronomy projects the 29" is still on the shelf. Charlie Green

Coulter sold a 29" mirror for a while, I remember that a SLAS member bought one and built a massive, classice Dob around it. I think it was Charlie Green, IIRC. Charlie are you still on the list? Wasn't it you who built that huge scope? I remember looking at some objects in Scorpius one night through it, at the old SPOC installation.
