Description

This wide-field multiple narrowband image includes from lower right advancing CCW, Sh2-223, Sh2-224, Sh2-225, and Sh2-227.  Three of these are HII regions dominated by Hydrogen-alpha emission.  The upper right, Sh2-224, is a supernova remnant showing nice oxygen emission.
This is an HOO rendering with Hydrogen-alpha as red and Oxygen III as teal (true color).  Sulfur is added in equal parts to red, green, and blue (white).
There are 9 exposures in each passband.
