This image by member John Crilly was captured on Thursday, July 15, 2010 from
his Urban Observatory in downtown Wadsworth, OH.
M20
(NGC 6514)
(Trifid Nebula) in the constellation
Sagittarius

Image details:
In John's own words: "No narrowband, just 20 minutes each
R,G,B. I have only an hour between the time M20 pops out from
behind a light fixture and the time it disappears behind a
tree. That whole region of sky is bright red (the center of town lies
that way) and I can see no stars at all. The teal OIII region
is much larger than this image reveals; most of it is dimmer than the
interfering light so it's lost in the noise. Some Ha and OIII
exposure would bring out the red and teal nebulosities much better
but it would take a dozen nights!"
Telescope: AT10RC (Astro-Tech 10" f/8 Ritchey-Chrétien
astrograph). Exposures: (see above) combined in post-processing.
Mount: Takahashi NJP German Equatorial.
