IC 2177 Seagull Nebula

This was a quick evening of just a few hydrogen alpha and Oxygen III images I grabbed on the RASA 11.  Was one of those that looked terrible right up until I almost said forget it, then it just looked sort of unique and I liked the contrast of just the two filters.  I plan to grab some Sulfur and eventually RGB stars, but like how it turned out for 2 filters.  Ha was mostly the green and red and the Oxygen was all blue.
