Description

A very tricky faint object. I had some issues with the Astrodon OIII filter flat fielding properly which complicated reduction considerably. I had to really clamp down the corners which probably compromised any nebulosity that might be present there.

I'd only taken H-alpha versions of this image previously so it was nice to at least have some color.

Description: Higher resolution version - avert your eyes!

It does show how nice and sharp the Canon 200mm lens can be. I have not done any sharpening on the image - the SNR wouldn't tolerate it...
