Astronomical Telescope FAQ
1. Is it means the higher the magnification, the better quality?
—- No!
2. Why some telescopes are so expensive? What are main reasons to influence the telescope price?
—1) The size of objective lens. The larger objective lens can collect more lights, which means the telescope with larger objective lens size can have clearer view when the magnification become higher and higher. Then it comes to the price, the lager lens, is more difficult to produce, it needs more time and more precise procedure to keep it in good quality.
—2) The other components of the telescope can also influence the price, for example: the tripod material, the main tube material, the lens of eyepiece quality etc,..

3. How to select a astronomical telescope?
Engaging into the astronomy interest
1) You need to know your budget,
2) Is the user a newbie? If yes, it’s better to have a entry-level model which normally is cheaper and easy to use. It would be more reasonable to have a more professional astronomical telescope after the user know more about telescope and astronomy.
The is some recommendation models:
Entry-level: YJ50360, YJ70300,YJ70400,YJ60700, YJ76700, YJ80500, YJ90700
Professional: YJ80900, YJ130650, YJ120900

4. What is the meaning of the telescope model?
For example: YJ50360, “YJ” is the brand sign, “50” means the objective lens diameter is 50mm, “360” means the focal length is 360mm
.
5. How to calculate the magnification?
Focal length ÷ eyepiece focal lens × barlow lens times
For example: YJ50360 telescope +20mm eyepice + 3x barlow lens
Magnification is: 360÷20×3=54
So the magnification is 54x
