I use a 450D and I believe there are other models which do both live view and longer than 30 sec exposure at a time.
Other makes can be used but I have no experience of these.
I only sold it because there were a couple of practical reasons why I wanted to get an ED80 which had convenient mounting rings on which I could mount a guidescope and a decent finderscope.
I recommend that you buy yourself a 2nd battery for the DSLR so one can be charging while the other is being used, although lately I have bought myself a cabled battery, as this runs off 12V and doesn’t need re-charging which means I can go to bed for a few hours and leave the imaging running without having to get up to change the battery.
It also slightly reduces the amount of heat in the camera and thus slightly reduces the noise, which is a problem in the warmer weather with DSLRs as they are not cooled.
I understand there are problems modifying some other makes of DSLR cameras which is a necessity if you are going to be able to capture the best data, but we will come to this later.
The camera will be supplied with an interface cable so you can attach the camera to a laptop, if not I recommend you get yourself one as trying to see through the viewfinder on the back of a DSLR and focus (just think of the awkward angles your camera might be at in pointing at your chosen object) I think must be an extremely - not mention back and neck achingly - difficult job.
However it becomes addictive and you’ll find yourself continuing to dig into your pocket long after you think you have bought everything you need.
Remember this is for imaging with a DSLR so I will not be covering planetary imaging though this can be done from the same set up.
Most imagers have more than one telescope - but watch the focal ratio (see next paragraph). Focal ratio is the focal length divided by the diameter of your objective lens.
For example, a refractor with a focal length of 900mm and an aperture of 100mm has a focal ratio of 900/100 = 9 or f/9.

However, I decided to leave this tutorial as it is because it is simple and from the feedback page you will see many people find it easy to follow and that's what this tutorial is all about - to help you get started.
