OK a newbie question here. I've had a good Celestron CPC telescope for about a year now and was interested in getting into Astrophotography this summer. I just got a digital SLR Camera (Canon) and already have a connector for the scope.

I was about to buy myself a wedge but then I thought I don't need that if I do ~30 second shots and stack the images.

Is this difficult to do? What software do I need?

Or should I just buy the Wedge?

TIA!
