The former is the magnification, 15 times; The latter is a caliber, 60 mm
This telescope is different from anything I have seen before. Not only are numbers different from letters, but there is also a degree behind them. What does that degree mean?
The degree is the field of vision, 6.5. 1 15m/1000m in front is also the field of view, that is to say, at the distance of1000m, the diameter of the field of view is115m.
How about this telescope? I bought it from Russia!
Generally speaking, Russian telescopes can basically be equated with fakes. After all, it has been almost 30 years since the disintegration of the Soviet Union, and the days of getting some light industrial products for Taobao have long passed. But this telescope may not be, at least not in the eyes of my fans:
The parameters are reasonable-15 times, 60mm, 6.5 field of view, all within the reasonable range of binoculars.
The parameters are exactly the same-6.5 visual field can match115m/1000m.
Photos and parameters can correspond, and there is no sense of cheapness (plastic parts and eyepieces can be coated).
So this should be a genuine telescope, which is absolutely enough for daily use (but it can be preliminarily judged that it is a bit heavy and the magnification is a bit large, so it is not particularly convenient to use). As for the fine workmanship (limit magnitude, resolution, coma, etc. ), you need to look at the moon or binary stars to make a calibration. This is not a simple judgment with half a photo and a few parameters.
