Seagull Nebula in HaRGB
-------------------------
IC 2177, also called "Seagull Nebula" (although it looks more like a rising phoenix spreading its wings), is a huge complex of ionized gas and dust 3,700 light-years away from us.
This is the result of a total of 15 hours of H-alpha (10.5 hours) and colour (4.5 hours) data on the Seagull Nebula.
Notable features:
Many interesting features of the nebula are visible in this image, such as the gas and dust structures in the Seagull's 'head' as well as in and around its 'wings'.
Also visible on the center-right, under one of the Seagull's 'wings', is a "bow shock": a shockwave created when radiation winds and outflowing gas from the double star system "FN CMa" interact with the interstellar gas of the nebula.
