|127mm achromatic objective and matching alloy tube for ATM fun!|
Purchased at Surplus Shed earlier this year, and never mounted. Air-spaced achromatic optics, multi-coated. 127mm clear diameter with a focal length of 1200mm making this an f/9.4. The aluminum barrel has a diameter of 145mm (OD), an ID of 135mm, and is 46mm long. The lenses can be easily removed (if needed) by unscrewing the retaining ring.
6" diameter, 48" long aluminum tube to make one heck of a yard cannon.
