Description
Manual equatorial tracking and long-focus observation define the Levenhuk AC 70/900 Blitz 70 PLUS EQ, an achromatic refractor with a 70 mm aperture, 900 mm focal length, and listed f/12.85 optical ratio. Its EQ-1 German equatorial mount uses flexible slow-motion cables and a counterweight, while the 5×24 finder, SR4, H12.5, and H20 eyepieces, 1.5x erecting eyepiece, diagonal, aluminum tripod, and accessory tray support lunar, planetary, and suitable terrestrial observation.
The aluminum optical tube uses a 1.25-inch rack-and-pinion focuser, while the EQ-1 mount requires manual alignment and direct cable adjustment to compensate for apparent sky movement. The longer 900 mm focal length supports the listed high-contrast visual format, and the erecting eyepiece provides upright viewing for suitable daytime subjects without requiring batteries, motors, or computerized object location.
