If you have a movie mode on your camera, you would be best off taking a short movie, then converting it into an avi then stack the image using Registax.
A lot of us got our start in astro imaging this way, just butting the lense up to the eyepiece.
Here's some of my early work using the same method with a clunky old brick of a video camera.
It just takes a lot of patience and practice.
