This will be a challenge...
I have tried on 2 occasions to capture the horse (& surrounds), and failed.
Alnitak dominates, and the horse is only just there.
This time around (if I can ever see the sky again) will go for low gain settings, to try and tame the bright star, & lots & lots of integration time.
Here is a link to what can be achieved by an amateur.

Good Luck!!
