***Thanks to a few friends, I've been informed these are Astro Systems Phase 3 focuser***

The entire base and platform are unitary and made of a very thick, durable composite plastic (looks and feels like the Trex Decks material). The leveling Allen screws arraignment is just like JMI NGF units.
Barrel size: 2-inches
Materials: composite hard plastics body, milled aluminum, brass, and steel
Weight: 1 pound 1 ounce
Total focus draw: 1.00-inch
Bolt pattern: (2) screws 4.00-inches apart lengthwise only
Will fit: any tube with outer diameter between 10.5-inches to 20+ inches
Payload: 1.7 pounds

The base on these focusers are flat, not curved. But because of the (4) leveling bolts, you can make them work on many different types of tubes. These were used on my Jupiter Telescope Co Juno 12.5, which was a hexagon tube and I didn't worry about the curve.

The one on the left does not come with the 1.25" adapter, nor the (2) mounting screws, but does have the (4) leveling bolts. Cosmetics are excellent and operation smooth and perfect. $70.00 sold

Price doesn't include shipping. Will ship to anyone on Earth.
