DSO 1 - First Imaging of the Orion Nebula

As I was dodging clouds here and there, I was only able to take four decent exposures but I was desperate to get my first bit of deep space imaging done. Here are the results:

OTA: 120mm Achromatic Refractor
Camera: Nikon D3100 14.2mp
Mount: CG-4 mount
Exposures: 4
Exposure: 20sec approx
ISO: 800

After consulting the forums, it's clear that I need to know light and dark frames very well. Whatever they are, they may help with my blooming stars, but I think a little more time focusing correctly will help too.

So there it is. First of many.
