Hanging plate accessories
Standard accessories include: × 3: SR4mm, H12.5mm, H20mm,
Extender lens × 1 times, upright lens × 1 times, other accessories 1.5 times, as shown in the figure below.
Maximum multiple: 350 times-you can clearly see the roundabout on the moon!
For other possible multiples: (focal length is 700mm)
SR4mm eyepiece only = 700/4 = 175 times. Paired with 2x Balow lens = 175 * 2 = 350x. Pair with 1.5 times Erector = 175 * 1.5 = 262.5 times magnified positive image. (for astronomical observation).
H12.5mm eyepiece only = 700/12.5 = 56 times. Paired with 2 times Boro mirror = 56 * 2 = 112 times. Pair with 1.5x vertical framer = 84x magnification vertical image. (for long-distance viewing).
H20mm eyepiece only = 700/20 = 35 times. Paired with 2x Balow lens = 35 * 2 = 70x. Paired with 1.5x erector = 52.5x erect image. (for sightseeing or watching games,
