Playing here with a Celestron autoguider. I've got a lot to learn, but this shot is already better than any unguided pic I've done. I use a piggybacked Orion 80mm scope to guide a Celestron C6R, which I use as a prime-focus lens for a Nikon D5100.
This is a 6-minute shot of the Orion Nebula. ISO is 800. The only thing I did to this photo is knock down the resolution to make a more manageable file size. I used no noise reduction or sharpening. Not bad, eh?
