How to identify the true and false Honghu telescope

Identify the true and false Honghu telescope, see if the caliber, field of view and coating are consistent with the product description, and check the security code.

For people who are not familiar with telescopes, all discrimination is to try to judge whether it is an irregular product from some clues on the surface.

At the same time, this judgment is not always reliable. For example, many inferior products now use green film or blue film as the formal coating of lenses, just like painting inferior furniture made of broken wood.
