IC 2177 Seagull Nebula
Captured the Seagull Nebula in Sulfur, Hydrogen, and Oxygen with a small 15% collection of RGB for stars over a couple nice clear rare evenings in January. This target sits low for me in the southern sky, but the F/2.2 of a RASA does a good job as do the new MaxFR 50×50 filters.
