A. About the function:
This can be used to look at the moon’s ring island with a gross weight of about 2 kg.Tripod height: 38CM.
B. About the configuration:
The focal length is 300mm, the diameter is 70mm, with 2 eyepieces: H6 (for daytime viewing) and H20 (for moon watching at night), plus 3 times Barov mirror and 1.5x mirror and moon mirror.Moon Mirror: Because there is a lot of reflected light interference when observing the full moon, using the moon mirror can eliminate these interferences and make the surface of the moon more clear.When using, please screw the moon mirror into the thread on the lower part of the eyepiece, then connect the eyepiece to the zenith mirror.
C. About multiples:
Separate eyepieces: H6mm, multiples of H20mm are: 300/6=50 times, 300/20=15 times.If you choose 3 times Barov mirror, then the multiple is 50X3=150 times, 15X3=45 times; plus 1.5 times the mirror, the imaging is positive, the multiples are: 50X1.5=75 times, 15X1.5=22.5 times.Namely: the minimum magnification: 15 times, the maximum magnification: 150 times.
D. Calculation formula:
Objective lens focal length / eyepiece focal length * several times Barov multiple = maximum magnification
Objective lens focal length / eyepiece focal length = magnification
E. Installation sequence:
The tripod is first supported.Then attach the lens barrel.After the lens barrel is fixed, a finder mirror (used to initially find the target object) is mounted on the lens barrel, and then the eyepiece is attached (eyepiece 2 is selected 1).After finding the big target, then debug with different eyepieces. Note: For the first time, be patient and patient!The possibility of bad astronomy is very, very small, not to mention the fact that every telescope we checked before was strictly checked.
F. Mainly look at the comprehensive factors such as caliber and focal length.
For example, if the windows of
