Model: F30070M
Tamaño de la caja de embalaje: 460×220×110mm Peso: alrededor de 2200 gramos
Clear aperture: 70mm
Focal length: 300mm.f/4
Oblique mirror: 90
Jingwei table and aluminum tripod
Maximum height: 38cm
Standard 0.965 inch accessories include:
Eyepiece: H6mm, H20mm 3 times Barov lens 1.5 times erect lens

The maximum magnification of this model: 150 times (objective lens focal length/eyepiece focal length * several times Barovs multiple = maximum magnification)

The caliber is the most important indicator for choosing a telescope, and the caliber is directly proportional to the sharpness and the price.



A. About function:

The gross weight of this model is about 2 kg, and you can see the round island of the moon. Tripod height: 38CM.

B. About configuration:

The focal length is 300mm, the caliber is 70mm, and it is equipped with 2 eyepieces: H6 (for daytime viewing) and H20 (for viewing the moon at night). In addition, it is equipped with a 3x Barov lens, a 1.5x erect lens and a moon lens. Moon mirror: Because there is a lot of reflected light interference when observing the full moon, using a moon mirror can eliminate these interferences and make the surface of the moon more clearly visible. When using, please screw the moon lens into the thread of the lower part of the eyepiece, and then connect the eyepiece to the zenith lens.

C. Regarding multiples:

Equipped with eyepieces: H6mm, H20mm, the multiples are: 300/6=50 times, 300/20=15 times. If you choose a 3x Ballov lens, the multiplier is 50X3=150x, 15X3=45x; plus the 1.5x ortho lens, the imaging is a positive image, and the magnifications are: 50X1.5=75x, 15X1 .5=22.5 times. Namely: minimum magnification: 15 times, maximum magnification: 150 times.

D. Calculation formula:

Objective lens focal length / eyepiece focal length * several times Barovs multiple = maximum magnification

Objective lens focal length/eyepiece focal length = magnification

E. Installation sequence:

Support the tripod first. Then install the lens barrel. After the lens barrel is fixed, install a star finder (used to initially find the target object) on the lens barrel, and then install the eyepiece (choose 1 from 2 eyepieces). After finding the big target, adjust it with different eyepieces. Note: The first time you use it, you must be patient and patient! The possibility of astronomical damage is very, very small, not to mention that every telescope has been strictly inspected before we release it.

F. Mainly depends on the comprehensive factors such as aperture and focal length.

For example, if the windows of a house are large, the light will be natural, and the view will be clear. The same is true.

G. When using a 3x Barov mirror, install the Barov mirror first, and then install the eyepiece.

(To install the Barov lens, you need to remove the cover on the device where the eyepiece is installed.)

H. Note: Only one eyepiece (H6mm, H20mm) can be installed at the same time.

Two extenders (3x Barov lens and 1.5x erect image lens) can only choose one at the same time.

I. Of course, the multiple is not unique, it mainly depends on the comprehensive factors such as aperture and focal length.

For example, if the windows of a house are large, the light will be natural, and the view will be clear. The same is true.
