Hi All,

This PN is, indeed, very color full.
This inside is, in the usual scale of C/S, color / saturation, a very vivid blue, C130/S70 or 80, whereas the Halpha appears on the circonference, C7/S30.

Here is my sketch, and the observation report at: http://www.deepsky-drawings.com/ngc-...7-2/dsdlang/en
