Description
Long-focus planetary and double-star observation define the Doerr AC 60/910 Merkur 60 AZ-2 Telescope, an achromatic refractor with a 60 mm aperture, 910 mm focal length, and listed f/15.2 optical ratio. Its AZ-2 alt-azimuth mount uses a fine-tuning altitude rod, while the SR4, H12.5, and H20 eyepieces, 2x Barlow lens, erecting eyepiece, star diagonal, Moon filter, finder, adjustable aluminum tripod, and accessory tray complete the supplied manual system.
The elongated optical tube and f/15.2 configuration provide the listed long-focus format for bright lunar and planetary targets, while the rack-and-pinion focuser accepts the supplied 1.25-inch accessories. The manual mount requires no power and can be repositioned directly in altitude and azimuth, with the fine-adjustment rod supporting more controlled movement during extended visual sessions.
