Is photography high because the visual acuity of astronomical telescope is not high?

The reasons for low definition are: poor quality of telescope lens, inaccurate focusing and bad weather. If these reasons are not, then there is something wrong with the eyes. Generally speaking, the best astronomical telescope is from Zeiss, Germany, and the Russian telescope is not bad. Generally speaking, domestic products are not good. Personally, it doesn't matter, but it costs a lot of money to do scientific research. The clarity of human eyes is not high, and photography is generally not high.
