The 'Rosette' Nebula in
Monoceros.
The
winter Milky Way runs directly through the diminutive constellation
Monoceros.
One of the showpieces in this area is the large
emission nebula (NGC
2237) surrounding the star cluster
NGC 2244. These
hot young stars (~ 4
million years old) energize the surrounding
gas and dust. The entire structure is about 100 light-years across
and lies about 5000 light-years away. For additional information and
images see the
Wikipedia entry.
This image was made from February 27 to March 6, 2010 and consisted of
almost 10 hours of
imaging, most of it for Hα. The image
data was acquired with an
STL11000
camera with an ASA 10N at
f/3.7 on an AP900 mount.
The data frames were acquired and stacked in
MaximDL. Final processing was
done in
Photoshop.

| This page illustrates what can be photographed using amateur telescopes and a CCD camera. I
currently use an
SBIG STL11000M
camera and have previously used a
SBIG and
Starlight
Xpress cameras, as well as a
Cookbook
245 camera that I built
myself. Most of the images were actually taken from my backyard near a busy street with
several street lights. Not only is the CCD camera a great imaging tool, but it allows
"real time" observation of objects not normally visible in areas with
moderate-severe light pollution. |
