Is it okay to connect the telescope with the SLR?

Of course, you can borrow a SLR, but pay attention to the interface type.

First of all, refraction, unobstructed view and large aperture are recommended. But as far as I know, the biggest refractometer on the market is MEADE 178mm, which should be automatically tracked. It's about 50 or 60 kilograms with equatorial equipment, which seems to cost 6000 dollars. Secondly, the SLR should be strong, and the SLR in Quan Huafu should be the first, such as Nikon D700, D3, D3x, D3s, Canon 5d, 1d, 1ds. These two combinations are absolutely awesome, check.

Since it is my personal suggestion to shoot animals, I still use the original telephoto lens of Nikon or Canon.
