As I am new to the forum I thought I would post one of my few images.
M42 taken with a Nikon D80 on my ED80. 800 ASA 10 subs each 60 seconds stacked.
Final processing in Photoshop

Not bad for a first image, well done.

The colours are a bit off though and you could really do with longer subs which will give you more data to play with.

I'm probably not the best person to comment as my experience barely spans two months, But....
As Mick said longer subs will help a lot and as get's pointed out to me quite often, a lighter background might reveal some more detail.

Otherwise there is some good data there and it's quite a respectable image.

The stars down the left look a little out of shape, were you guiding?
Which mount are you using?

Shoot for the stars, reach the tree tops!

I am using an eq5 synscan mount.
The image was not guided, hence the short exposures.
I am trying get guiding up and running using PhD and a finderscope with webcam.
I have only had one go at it due to the weather and that gave me egg shaped stars after two minutes.
I think that my balance was not perfect.
Once the weather clears I will have another go. So I will post an update sometime in the future.

If you are using a webcam also try MetaGuide if you can't get PHD to work.

Thanks Mike, I will bear it in mind for the next session. (If the weather ever clears.)
