|John, from Richmond, Virginia, and his 7" refractor. The tripod is a Losmandy|
while the "mount head" is a rocker box.
|John asked for larger altitute bearings with a "break" on each axis.|
|The altitute bearings are 10.5" in diameter while the length of|
the "rocker box" is approximately 30".
|The altitude bearings on John's tube rings. nice!!|
