1. Is it means the higher the magnification, the better quality?
—- No!
2. Why some telescopes are so expensive? What are the main reasons influencing the telescope price?
—1) The size of the objective lens. The larger objective lens can collect more light, meaning the telescope with a larger accurate lens size can have a clearer view when the magnification increases. Then it comes to the price, the larger lens, is more difficult to produce, and it needs more time and a 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 central tube material, the lens of eyepiece quality, etc,.
3. How to select an astronomical telescope?
Engaging in the astronomy interest
1) You need to know your budget,
2) Is the user a newbie? If yes, it’s better to have an 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 knows more about telescopes and astronomy.
The are 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 eyepiece + 3x Barlow lens
Magnification is: 360÷20×3=54
So the magnification is 54x
