APOD: The Seagull Nebula (2015 Aug 29)

Post by APOD Robot » Sat Aug 29, 2015 4:09 am

Image The Seagull Nebula

Explanation: A broad expanse of glowing gas and dust presents a bird-like visage to astronomers from planet Earth, suggesting its popular moniker - The Seagull Nebula. This portrait of the cosmic bird covers a 1.6 degree wide swath across the plane of the Milky Way, near the direction of Sirius, alpha star of the constellation Canis Major. Of course, the region includes objects with other catalog designations: notably NGC 2327, a compact, dusty emission region with an embedded massive star that forms the bird's head (aka the Parrot Nebula, above center). Dominated by the reddish glow of atomic hydrogen, the complex of gas and dust clouds with bright young stars spans over 100 light-years at an estimated 3,800 light-year distance.

Whilst this is a lovely image, I'm perplexed that APOD never includes images that show the whole entire Seagull Nebula, only a closeup of the central part? :?
Also the bowshock in the bottom right corner is very nice, I would love to see a HaOIIIRGB closeup of this by somebody with a larger telescope.

It's really difficult to see a bird in this portrait! :?

Smile today; tomorrow's another day!

I thought so too. From a wider image it becomes more apparent.

Check out old black & white photo's from a smaller telescope, such as these.

Especially the 7th one from the top left.
