IC 5146 - the Cocoon Nebula (HaRGB)

An especially fun target to shoot, because it's a combination emission and reflection nebula. The red in its center is ionized hydrogen, which emits a deep red glow, but the areas around the nebula with fewer stars are filled with dust, which reflects nearby starlight to produce the pale blue glow at the nebula's apparent edges.

Shot at 1600mm with a 200mm RC telescope and a ZWO ASI533MM Pro. 2h of Ha integrated exposure time, plus 1h each of RGB data.

All images on my blog, unless noted, are shot from my backyard in Bortle 7 skies.

I told you I’d reprocess later. Just another hours worth of data for a total of 2 hours. 60 flats, 60 darks, and 60 dark-flats processed in PI. I’d like so much more data but damn I’m tired. I relent. A good practice for doing multi-night imaging however.

I got in another astrophotography session Tuesday night. If the Flame Nebula looks off, it's because it was close enough to the moon for stray light to hit my scope.
