Description

As a "target of opportunity", M33 presented itself as a little challenge during the actual development. It's limited surface magnitude makes processing a bit tricky, trying to eliminate the background while maintaining the faint galaxy structures. HAlpha merging was then done manually with PixInsight and PixelMath.
