main indicators:
A. About function: This lens barrel is about 0.83 meters long, the highest tripod is about 126cm, and the gross weight is about 5 kg. The moon circle island can be seen very clearly.
B. About configuration: focal length is 900mm, aperture is 60mm, with 3 eyepieces: SR4 (for daytime viewing), H20 (for viewing the moon at) and H12.5 (for viewing other celestial bodies). In addition, it is equipped with 3 times Barov mirror and 1.5 times erect mirror.
C. Regarding multiples: equipped with eyepieces: SR4mm, H12.5mm, and H20mm. The multiples are: 900/4=225 times, 900/12.5=72 times, 900/20=45 times. Coupled with a 1.5x erect lens, the imaging is a erect image, and the magnifications are: 338 times, 108 times, and 67.5 times. If you do not install a 1.5x erect mirror, but a 3x Barov lens, the magnifications are: 675x, 216x, 135x. In other words, if we choose the eyepiece SR4mm, coupled with a 3x Ballov lens, then the maximum multiple of 675 times can be combined. Namely: minimum magnification: 45 times, maximum magnification: 675 times.Find answers in product info, Q&As, reviews
