I have nothing to add other than "good job" as well as that I love how faint and silhouetted this nebula is...I find that really beautiful in a weird way. It just seems so faint and fleeting...it must be a real rush to see it through an eyepiece.
Sadly, I have more chance of winning the lottery then ever seeing this particular DSO from my light polluted skies with my XT8.

It's very faint, but if you have a dark enough site with clear, moonless skies, it is possible to see the Horsehead, but it will be a dark notch in a strip of dim nebulosity that has a sharp edge on one side, but fades to nothingness on the other gradually. Your eyes need to adjust to the darkness and you'll want to look for it when Orion is high in the sky. A hydrogen beta filter will help a great deal, and it works on other weakly energized nebulae such as the Cocoon and California nebulas. If you look near Alnitak and can see NGC-2024, it means you have a shot at the Horsehead. If NGC-2024 or the Flame nebula is not visible, you can be sure there is no chance of seeing the Horsehead. In both cases, keep Alnitak out of the field of view so its glare does not interfere.
