Leo Trio: M65, M66, and NGC 3628
M65 is the spiral
galaxy at upper right, M66 the spiral at lower right, and NGC 3628 the edge-on
galaxy at the left. The total field of view is approximately 45 arcmin high x 65
arcmin wide. North is at upper left in this image.
I was pleasantly
surprised by the amount of dust lane detail brought out by the DDP processing in
MaxIm. Presumably the long total exposure (collected over two nights)
helped. However, the raw frames of this CCD image were plagued by
gradients and required extensive manipulation before and after combination to
neutralize the background sky color.

Astro-Physics 130 EDFs
refractor at f/6 with ST-10XME CCD camera at -15 °C
A-P 1200 GTO mount.
Guided with the internal guide chip. SBIG CFW-8 filter wheel.
Twenty 5 min exposures
R and G, seventeen 5 minute B exposures (cut short by weather). Total
Raw frames calibrated
with Wodaski's Debloomer plug-in in MaxIm 3.09. Master R, G, and B
frames were then
created and Wodaski's gradient removal processing was then applied to the individual color
masters. The RGB color combine was then carried out in
MaxIm. The image was then imported into
and adjusted with Levels, Curves, and Color correction.
Finally, smoothing was applied with SGBNR.
