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.
