Takahashi FSQ106
OGS 10" RC
SBIG ST10XME
SBIG STL11K

This is an example of a
hybrid composite image, a
term coined by noted astro-
imager,  
Rob Gendler. The
wide-field data was acquired
by
Jim Misti using the
FSQ/STL combo at his
Arizona observatory. After
processing the LRGB data,  
I then layered in my older
(HaGB)(HaR)GB data of
M8
taken with the FSQ/ST10
combo from Pennsylvania. I
also layered in additional
data of
M20 taken with the
RC/ST10, but the gain in
resolution for M20 is only
appreciated at high
magnification.

The data was processed
with CCDsoft, Registar, Neat
Image, and Adobe PS.
The Region of the Lagoon & Trifid Nebulas
              Click on image to enlarge
These nebulas are found in
Sagittarius, and when
looking in this direction, one
is also looking towards the
center of our Milky Way
Galaxy -- hence, the image
is replete with stars by the
millions, and the combined
light of those suns produces
the golden glow that is most
pronounced towards the left
in this image. The dark
zones are large collections
of dust that obscure our view
of what's behind them. In
addition to the famous
Lagoon (M8) and Trifid
(M20) nebulas, this region
also contains other emission
nebula, most notably to the
left of the Lagoon.
Click HERE to see a close-up version of the Lagoon, and use a
mouseover to view the backround stars as an LRGB from
Arizona, or as an HaRGB from Pennsylvania (near Philadelphia)
-- the point being that local light pollution in PA virtually
necessitates the use of a narrow band filter on this object -- the
Ha filter effectively captures fine detail in the nebula, but greatly
suppresses the starry backround.
