Imaging and Interpretation of Astro-Photographs
Although the same subject as a recent image post, this is actually a new image taken with my Televue 127is telescope, and processed to highlight the eddies and turbulence that exists within the molecular cloud. In this case, the primary

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?)
