Standard 0.965 inch accessories include:
Eyepiece: H6mm, H20mm 3 times 1.5 times as mirror Barlow lens
The maximum magnification: 150 times (focal length / eyepiece focal length * several times ballauff ratio = maximum magnification)
Aperture is the most important indicator of the telescope, aperture and clarity and price is proportional.
A. on function:
This can be around 2 kg gross, you can see the moon’s ring island. Three foot height: 38CM.
B. about configuration:
The focal length is 300mm, diameter is 70mm, with 2 eyepiece: H6 (daytime with the view) and H20 (see the moon at night), with another 3 times and 1.5 times as Fujing Balotelli and moon mirror mirror. Moon mirror: because of the large amount of reflected light that is observed at the full moon, the use of the moon mirror can eliminate the interference and make the surface of the moon clearer. When the utility model is used, the moon mirror is screwed into the thread at the lower part of the eyepiece, and then the eyepiece is connected with the zenith mirror.
C. about multiples:
With eyepiece: H6mm, H20mm multiples: 300/6=50 times, 300/20=15 times. If the optional 3 times are multiples of the Barlow lens, 50X3=150 times, 15X3=45 times; plus 1.5 times as mirror imaging is positive, multiples are 50X1.5=75 times, 15X1.5=22.5 times. Namely: the minimum magnification: 15 times, the maximum magnification: 150 times.
D. formula:
The focal length eyepiece focal length * / several times the maximum magnification ratio = ballauff
Objective focal length
E. installation sequence:
Three legs to stand up,. And then put on the barrel. The barrel is fixed, installed in the finder lens above (primarily target objects), and then loaded on the eyepiece (2 eyepiece 1). To find a large target, and then with different eyepiece debugging, attention: first use, must be patient and patient and patient! The possibility of astronomical damage is very small, not to mention we have issued a rigorous inspection before each telescope.
Of course, F. multiplier is not unique, mainly depends on the aperture and focal length and other factors.
For example, the large windows of the house, the light is good, see also clear, is the same reason.
When using G. 3 times Fujing Balotelli, first installed barov mirror, and then put the eyepiece.
(loaded barov mirror, need to put the lid on the eyepiece device installation removed.)
H. note: 2 eyepiece (H6mm, H20mm) can only select 1 installation.
2 doubler (3 times 1.5 times as Barlow lens mirror) also can choose 1.
Of course, I. multiplier is not unique, mainly depends on the aperture and focal length and other factors.
For example, the large windows of the house, the light is good, see also clear, is the same reason.
