ATMs seized upon this idea as being compatible with the ATM workhorse: the Dobsonian-mounted telescope. Mel Bartels has designed a system

Self-construction of a mount like this enables the ATM to design it from scratch and suit it entirely to his needs, as Scott Wilson shows in this integrated moun
