Does anybody know if (former SAC member) Mark Pritzl is still located in Black Canyon City? I seem to remember he was the fellow who bought the surplus Celestron 18 parts from SAC some years ago, and converted the metal welded fork parts into a large alt-az Dobsonian. Or do I have the name wrong? Please respond off line if you have any info, thanks. Gene Lucas (17250) gene.lucas@xxxxxxxxxxxxx
