The standard textbooks indicate that the start or conception of a new star formation is the collapse of a molecular cloud. But my background in thermodynamics, heat/mass transfer and fluid mechanics leaves this superficial explanation ungratifying (at least to me?)

Ou4 (The Squid Nebula) represents a nice challenge to astrophotography and I find myself going back to it almost annually to try another technique and see if my skill and available processing tools have improved. As part of my new
