[ATMoB-discuss] Finally...an image to post! (DWB-111)

[Neil Fleming]

It's been a long time coming, but finally an image to
post!! <g>

This is DWB-111, The Propeller Nebula, a.k.a., Simeis
57 or MRSL 479, an emission nebula in Cygnus.

About 12 hours in total...presented through three
images; one illustrating the Hubble Palette
(SII/Ha/OIII), the second illustrating a synthetic
green approach (Ha/sG/SII), and finally, the H-alpha
data on its own.

I hope you like.  As always, comments and suggestions
are greatly appreciated.  I've been twiddling with
this one for weeks...

   ...Neil
