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 unique question mark appearance of M51, its size (77 thousand light years, 90% of Milky Way) proximity to us (only 31 million light years) made it a galaxy of interest for me, so I brought it in for some

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?)
