Nebula looking for a name, Ced 117 in Centaurus.

Hi,

This is part of the complex around IC 2944 and does not appear to be imaged often on it's own. It's designation is Ced 117 in guide 8.

Here's some limited info..

Ced117
Maximum diameter: 900 arcseconds
Emission nebula
Brightness level: 5 (1=brightest, ... 6=faintest)
Brightness level extremely approximate
Alternative designations for this object:
Ced 117
GN 11.28.1
RCW 61

It was a frustrating image to process!!!
There seemed to be a lot of foreground dust, ( I'm guessing ) which obscured details of the nebula. A soft light background apply image of 25% in PS seemed the most effective in overcoming this. Anyway this is my effort.
Equipment.

8" Newtonian astrograph f/4. on HEQ pro 5 mount. Orion mini guider.

Unmodded canon 1100D, baader coma corrector type 3.

17 x 9 minute subs, iso 800, stacked in DSS, processed in PS7.

Cheers,

Justin.
