HOW TO USE THE TELESCOPE
VARIOUS APPLICATION OF DIANFAN TELESCOPE
Q1: What kind of weather is suitable for observing with a telescope?
A: Please choose a calm and cloudless night for observation to minimize airflow disturbance. Because atmospheric conditions such as high wind or severe atmospheric turbulence may affect the observation.
Q2: Why is it difficult to see planets or nebulae in cities?
A: Light pollution such as city lights can mask faint objects and make them difficult to observe. Please go to dark areas away from the city (e.g., suburbs, mountain tops) to get a clearer image of the celestial objects.
Q3: How to make the tripod more stable?
A: Adopt a more scientific way of placing the tripod and try to make sure that you use the tripod on flat ground. If you use it on uneven terrain, make sure one leg is facing the direction of the telescope's observation target to improve stability.
