Witch Head Nebula IC2118 -Eridanus

Hi All. Here's one I collected at the VicSouth Star Party last month. It's 5 hours of data (LRGB 150:50:50:50) through a Takahashi TOA130/EM-200 combination and SBIG STL11000M camera. Processed in CCDStack and Photoshop CS5.

I'm learning all the time about subtleties of image processing and there's much yet to learn. I couldn't process the faint parts without burning out the cores of the brightest stars. There are hints of emission nebulosity in the field and the blue illumination at lower right is from Rigel.

Suggestions and comments welcomed.
