John pretty much covered the approach. The Horsehead can be found but as Allan pointed out a very dark site is a prerequisite. As indicated it is black on slightly less black, so knowing exactly where to look helps enormously. Obviously good vision is important. Also "averted vision" can sometimes find it when looking directly at it doesn't. I recall looking at it at Chaffey Dam dark site, with my 16" Dob, and not being really sure till I looked slightly away, where I had better light/dark perception.
Despite the challenge that the Horsehead represents visually, it is easy to video image with a plain colour high frame rate camera; but the human eye lacks the ability to build an image over time. If you want to try EAA, where you use a high frame rate camera and software like Sharpcap, it will jump right out of the screen at you as Sharpcap stacks frames (which no human eye can do). In my opinion, being of advanced years and not so good eyesight now, it is much more rewarding seeing it through EAA in real time.
