Yes, this camera has the standard screw hole for tripods. 

As long as it has the standard 1/4" thread on the underside Yes. 

You can adjust the ball head to aim the camera down, but the next tripod up from this is probably better for overheads 

K&F Concept camera tripod you are asking, yes, you Canon rebel sl2 could be used on our tripod. Your camera could be used as long as it has a 1/4" standard screw interface; If your lens is large or telephoto zoom lens, please ensure to expand the leg angle, and hang some weight to the hook to increase its stability. For camera with telephoto zoom lens, you need to buy a tripod mount ring additionally for better balance.The center column also has a hook to hang weight on to lower the center of gravity on this tripod to make it more sturdy and less prone to vibrations which is awesome for photography where you take long exposures . 

Just about. However I feel that if it’s planets you’re going to be looking at, then you perhaps would want something more stable and less light weight. The tripod is lightweight and very portable so if these things are important then yes it will work. 

Hi, I use it with a canon DSLR camera and it's really sturdy, I would assume if the wildlife camera can be attached then yes it should do the job. 

Binoculars? If it has a standard tripod thread then yes. But the hight it goes to would mean you would have to sit it use them and I think the legs would get in the way. Better off with a monopod that adjusts to a higher level. 

Absolutely, yes. I use a Sony a6400 and its a good sturdy tripod in all conditions. 

Yes. The head is the same for all models so it will be the same quick release plate. 

Yes this tripod is compatible been using my eos 7 mark ii for months now and is great hope this helps
