Canon SX40 HS is a good consumer telephoto machine. If you want to protect the lens, you need a protective mirror (UV mirror) first, but you need to add an SX40 adapter (available online) and a switch from 52mm to 67 mm.

Mm stands for caliber, that is, diameter. You should buy protective glasses first (that is, anti-ultraviolet glasses, which are good for Jiangao). There are many kinds of filters, each with a different usage. Don't buy it wrong.

Buy a tripod, just choose a domestic one, a few hundred pieces are enough, there is a tripod on it, and the camera is installed on the tripod and can be adjusted.
