Ngc 7793

This galaxy is described as a chaotic spiral and is a member of the Sculptor group. It was imaged over 5 nights under generally poor conditions (intermittent clouds and mostly bad seeing.) I would have liked more data and the luxury of dumping some of the weaker subs but the weather didn't allow it this year.

I do particularly like the assortment of small fuzzies in the background. There's also a pink spot on the outskirts of the galaxy at about 5 o'clock which is apparently a microquasar composed of a normal star and a stellar-sized black hole.

Scope: Ceravolo C300 @ f/9 = 2760mm FL, Atlas focuser
Mount: AP900
Camera: U16M
Filters: Astrodon E series Gen 2 LRGB
Guiding: Lodestar / MMOAG
Image scale: 0.67 arcsec/pixel
Exposures: 19x1200s L, 8x900s R, 7x900s G, 9x900s B

High res version, warts and all, can be found on Astrobin: http://www.astrobin.com/133431/

Thanks for looking. Constructive comment is appreciated

Cheers,
Rick.
