What's the difference between a telescope for observing deep space and a telescope for observing planets?

1. The main difference is the magnification and aperture. Deep space is bigger.

2.400 times, in fact, is the effect of stretching 400m to 1m, which actually has an objective impact on the environment, and the effect is discounted. The magnification is too large for personal use.

3. Both folding mirror and reflecting mirror can be used for photography. Mainly depends on the matching degree and maneuverability. If you take a picture, you should also consider the degree of restoration of the image.

4. There is nothing absolute. The large aperture only increases the amount of light, mainly the optical effect of the lens.

If you buy, don't buy extreme, only the right one is the best.
