Hi,
first of all, welcome to BF!
Most scopes can be used for imaging, it helps if you one with ED glass as chromatic aberration is quite prominent in images.
If your focus is not on watching birds but digiscoping, you might want to ask also in the digiscoping forum. And it would be helpful to know what type of camera you plan to use too.
In general, there's many ways of taking pictures through a scope - see the link below - never mind the fact that Televue is mainly about astro scopes, the principles are the same.

Usual ways for spotting scopes are the following:
Method 3 Focal length extended by Barlow/Powermate, although this adapter is usually called TLS-APO with spotters: Screws onto your scope body on one side and has a T-mount thread on the other. You can get a T2 adapter for your DSLR and attach it - you use the scope as a slow and long tele prime lens, manual focus only. Find the focus peeking and focus loupe options of your camera! Effective focal length is usually 600 to 1200mm, focal ratio 8 to 12.
Method 4 Eyepiece Projection: You get an adapter which can be screwed onto your EP or onto an accessory thread on the body so it covers your EP and has a T mount thread on the camera side. Once again, you mount your camera with a T2 adapter. Effective focal lengths is usally in the 1000-3000mm range and focal ratios are f10 to f30. Manual focus only.
Method 5 Afocal imaging aka digiscoping: you get an adapter to put your camera (including lens) or smartphone cam behind your EP. Effective focal length is focal length of your camera lens times the magnification of scope and EP - can get very long but usually low magnifications 20-30x are used together with a not too long tele. Focal ratio is scope aperture / effective focal lenth - can get very slow. On the plus side, you camera AF can work (to a degree, it won't work if the focus in the scope is totally off).
As you can see, in all cases the effective focal lengths are quite long and the focal ratios correspondingly slow, so you want:
a) a sturdy tripod and head - more so than for visual
b) a camera with good low light capabilities
