Have a look at
http://www.televue.com/engine/TV3b_p...n=Advice&id=85 for some advice on different imaging methods.
You will at the very least need a Canon EOS T-Ring to connect to your camera body (without lens). Then if you want to photograph at prime focus you need a 2" T-adapter. That connects to the T-ring and slips into the focuser. The focuser needs to be low profile or you won't reach focus. Normally telescopes suitable for photography require extension tubes when used visually.
The above is prime focus photography and your telescope is a 1200mm f4.7 prime lens. The advice on the Tele Vue site mentions other methods. Eyepiece projection is possible with another adaptor to hold the eyepiece in place, (still no camera lens). Afocal is with camera lens attached also known as digiscoping. Note your f ratio and effective focal length increases significantly with eyepiece projection and exposure times increase too. The best method for capturing planets is with video and software that selects the sharpest frames and stacks them together. Deep sky is best at prime focus. Note without a proper equatorial mount you will get field rotation that is noticeable at longer exposures.
Your 5mm eyepiece will be good on only the nights of best seeing. You may want to complement it with something around 7-8mm.
Enjoy!
