main indicators:
Refraction/focal length: 900mm, aperture: 60mm
You can multiply by 45 times, 72 times, 225 times, 1.5 times, 65 times, 108 times, 338 times, 3 times, 135 times, 216 times, 675 times.
Visual penetration strength: 11.40 etc.
Theoretical resolution: 1.842 seconds, which is equivalent to seeing two objects at a distance of 0.893 cm at 1000 meters.
Light: 0.109
A. Function: The lens barrel is about 0.83 meters long, the largest tripod is about 126cm, and the gross weight is about 5kg. You can clearly see the moon circle island.
B. About configuration: focal length is 900mm, aperture is 60mm, equipped with 3 eyepieces: SR4 (viewing during the day), H20 (viewing the moon at night) and H12.5 (viewing other celestial bodies). There are also 3x Barov mirror and 1.5x front mirror.
C. Regarding multiples: eyepiece: SR4mm, h12.5mm, H20mm, the multiples are: 900/4 = 225 times, 900 / 12.5 = 72 times, 900/20 = 45 times. Plus 1.5x mirror, the image is positive,
D. The multiples are: 338 times, 108 times and 67.5 times; if the mirror is not 1.5 times positive, but Barov's 3 times, the multiples are: 675 times, 216 times, and 135 times.
E. Choose the eyepiece SR4mm and match the three times Barov reflector, we can get the maximum 675 times, that is, the minimum magnification: 45 times, the maximum magnification: 675 times.
