Description
Optical system: RefractiveClear aperture: 70mm (2.4 ″)
Focal length: 300mm
Oblique mirror: 90 °
Warp and Weft Platform and Aluminum Tripod
Maximum height: 38cm
Standard 0.965-inch accessories include:
Eyepiece: H6mm, H20mm, 1.5X,3x Barov
Maximum magnification of this section: 150x (objective focal length / eyepiece focal length * several times Barov multiple = maximum magnification)
A. About function:
You can see the circular island of the moon. Tripod height: 38CM.
B. About configuration:
The focal length is 300mm and the caliber is 70mm. It is equipped with two eyepieces: H6 (for daytime viewing) and H20 (to see the moon at night), and a 3x ,1.5X Barov lens.
C. About multiples:
Eyepieces: H6mm, H20mm multiples: 300/6 = 50 times, 300/20 = 15 times. If a 3x Barov lens is selected, the multiples are 50X3 = 150 times and 15X3 = 45 times; D. Calculation formula:
Objective focal length / eyepiece focal length * several times Barov multiple = maximum magnification
Objective focal length / eyepiece focal length = magnification
D. Installation sequence:
Support the tripod first. Then attach the lens barrel. After the lens barrel is fixed, install a finder lens (used to initially find the target object) on the lens barrel, and then install the eyepiece (eyepiece 2 chooses 1). After finding the big target, then debug with different eyepieces. Note: For the first time, be patient and patient! The possibility of astronomical badness is very, very small, not to mention that every telescope has been strictly checked before we released it.
E. When using a 3x Barov lens, first install the Barov lens and then the eyepiece.
(To attach a Barov lens, you need to remove the cover from the eyepiece-equipped device.)
F. Note: Only two eyepieces (H6mm, H20mm) can be installed at the same time.
