M31 Mosaic

Hi all:

Here is an LRGB image of M31 and its satellites. This is a 4 panel mosaic. This is my first mosaic ever, and I must say processing this was a challenge! North is to the right. If this image is properly oriented, the foreground dust lanes make M31 look "upside down" to my eye, like an inverted bowl.

This image was taken with the following equipment:

TEC APO 140
Astro-Physics Mach 1
FLI ML 11002M camera
FLI PDF focuser and Filter Wheel
AstroDon LRGB 2” filters
Maxim DL
CCD Commander
Registar
Photoshop CS2

The final 16 bit tiff image is an enormous 158M. A somewhat compressed 8 bit jpeg at full scale may be found here:

I like the L channel quite a bit as a black and white image. It may be found here, at full scale:

Thanks for any comments!

Jim

Jim that really looks nice. I enjoy astrophoto's when they aren't stretched and look natural. This picture is really beautiful. Martin

WOW! That is gorgeous, Jim. Great color, very nice stars. The H-alpha regions, the core detail, the seamless mosaic, all superb. A lot of work, but well worth it!

That's a fine rendition, Jim.
The seams are seamless () and the color is not overwrought.
My regards,

Jim,
That is a mighty fine image. Panels came out seamless. I like the full size RGB. I know what you mean about M31's orientation. I really needs thte orientaion you gave it for best viewing.
