I should add that the Celestron Nexstar 8se is capable of working with DSLR cameras. But it is a 203mm mirror that is f10. This means that it is a 2030mm focal length. I have the next model up with the Celestron NexStar Evolution Telescope, 9.25".
Be aware that 2030mm focal length is really too much focal length for easy use. Celestron also sells a focal reducer.

Still a lot, but more manageable. And then you need a T-Mount adapter.
I have not tried my full frame camera with my 9 1/4" scope and I am not sure if there would be vignetting.
Next thing to be concerned about is that the mount is an Altitude-Azimuth type mount. This mount is up/down and left/right. When you look at a night object, even though you are tracking, the image will rotate in a circle. Its perfect for visual observations but not so good for camera tracking. I have a mount like this for my scope also, but I don't use it with my 9.25" scope because of this problem. Instead, I use an equatorial type mount which produces no field rotation.
But the Alt-Az mount is really nice for use with my camera and shorter focal length lenses since the shorter the focal length, the less of a field rotation effect you see since the rotation is reduced accordingly.
The Celestron Nexstar 8se comes with I believe is just one 40mm eyepiece. The one I got had a narrow apparent field of view. This mean when looking through it, it reminds me of looking through a paper towel tube in that everything seems to look so far away. Instead, I bought some nice Baader eyepieces that have a 68 degree apparent field of view and the view is so much nicer in that you feel like you are out there among the stars.
I also have other scopes since each are better for different objects. My low power scope is only 300mm and is good for nebula. I have a 4" refractor with a focal length of 710mm which is good for star clusters and galaxies. Also have an 8" newton reflector. Gathers more light than the 4" refractor. But the refractor is more fun to use.
This should give you a short overview. Starting with the Celestron Nexstar 8se may lead to frustration as the first scope. The long focal length is difficult to handle.
And there are other things to consider such as finder scope, and a red dot site to get you close before using the finder.
The Alt-Az mount is easy to align since you only need 3 bright stars and it figures out where you are looking. It is more effort with the equatorial mount since it is a more complex alignment process.
