IC 5146 Cocoon Nebula

[BlueAstra]

Still working on collimation, but this is a shot of the Cocoon Nebula with the current setup. Really must get some flats though! 5x240s L + 5 60s RGB @ 2x2, AG10+EQ6+SX(OAG+FW+H16+Lodestar). Thought I'd see what F/3.8 was capable of, hence the 60s RGB. Not quite long enough though, I think there's too much noise at 5x60s.

Very nice first shot Actually I think you'll find that's the Trifid Nebula

Very nice shot. I agree a bit noisy but still shows a lot of detail.

Gina - Unfortunately your wrong. It is the cocoon nebula. The cocoon and trifid do look look a lot a like. They both have 4 "dark dust arms". But one of the cocoons arms (the SW one in this image) has a distinct perpendicular dust lane at the end. Where the trifid all the arms look like the wrap around.

That's stunning!!

OK - it just looked more like the Trifid to me as in this view - Trifid at top, Lagoon at bottom

Oh i agree with look on that Gina. That look very much alike. Especially when the emission nebula is already faint and doesn't always show up when you dont have enough exposure time.
