Firstly, there is no such thing as a dumb question.
The usual sequence is, attach the camera to the telescope vide a T-Ring with the appropriate Canon EOS adapter. Now, this next step is dependant on whether you have the appropriate cables or not, for the moment use the USB download cable that came with the camera, plug it in and also plug it into the Laptop. Your Laptop should pick it up immediately and a download screen will appear, click out of that and start DSLRFocus, connect the camera in DSLRFocus and go to focus mode, there is a default screen of 4 seconds exposure and 800 ISO, click your spacebar to take a photo, on the downloaded photo, move it around until you get a not to bright star, click on it then either rack your focus in or out until you get the highest value, on your scope, lock the mirror AND double check the focus again incase of slight mirror movement. Then go to the expose mode. I would go to the object you want first, then focus, with an SCT you have the problem of mirror flop, better to focus on a star near the object.
Bear in mind that you will be limited to 30 second exposures with the USB cable. You will definately get trailing without a wedge and it will happen quickly at f/10, 2500 mm focal length.
For long exposures you need to get another cable.
Hope this helps a little.
