The goal was to get the arms as long as possible (you can see some small galaxies at extremities )
and the possible details in the arms
For this version, I added the Halpha layer and try to keep saturation at a low level
M74 finally looks like a small M101
Wiki :
Messier 74 (also known as NGC 628 and Phantom Galaxy) is a spiral galaxy in the constellation Pisces. It is at a distance of about 32 million light-years away from Earth. The galaxy contains two clearly defined spiral arms and is therefore used as an archetypal example of a grand design spiral galaxy. It is estimated that M74 is home to about 100 billion stars.
