First attempt at the Horsehead Nebula

An excellent seeing last night, so i tried to photograph the Horsehead Nebula with my C8. Unfortunately the 2m focal length without focal reducer is not the best solution...
The result of 50 min integration is very poor, the horse is hardly visible on the right side; the light on the left is the star Alnitak and you can see part of the NGC 2023 at the very bottom:
