Is green film better than blue film for telescope lenses?

Green film is a multi-layer film system, its transmittance enhancement effect is more average in the whole visible wavelength range, and it can get more real and natural observation colours. Blue film is generally a single-layer magnesium fluoride transmittance enhancement film, its transmittance enhancement effect in the red light area is better, the blue light area is more reflective (so it is light blue or mauve), this characteristic will make the final imaging colour is reddish, the colour is slightly distorted.

How far can a telescope see?

Telescope is our eyes can see can see, for example, such as a thousand metres away, I am using 10 times the telescope, the equivalent of my eyes to see 100 metres away. Generally, a telescope with a fixed magnification can see a person's face within 600 metres and a person's silhouette outside 5 kilometres, and if the weather is good and there is less dust in the air, you can see even further.
