IC 410 is an emission nebula approximately 12,400 light hears away. The brighter gas structures are lit by radiation and stellar winds from NGC 1893, the embedded star cluster. The cluster is only about 4 million years old. The two brighter structures at lower left are colloquially named The Tadpoles.
I shot the Ha while the moon was up, and not knowing how much it would be washed out by moonlight, I got a fair amount of signal. The Ha didn't dramatically change the image as it does with some nebulae, but it did allow me to significantly highlight many of the brighter structures.
