The Bulb setting is for when you are doing long exposures , using a remote timer.
For Moon shots, try ISO200 and 1/250th sec. But experiment as was mentioned before.
To attach your camera to the scope, you will need a T Ring to suit an EOS camera.

You may need to purchase the nose piece to suit as well, if your adaptor in your focuser isn't threaded to suit.
