Vibes: "Black Mermaid" by Esthero
How? A friend comes over, we chat over tea. Another friend comes over, I introduce them, they click and start chatting. The Sun is going down, I need to take this photo before the light is gone. I excuse myself and let my friends chat, grab the tripod, the remote and a little end table, go in the sunroom, take my clothes off, slip this lacy black gown on, balance on the table and take about 10 photos. Slip my clothes back on, put everything back, my friends did not even notice I was gone. Whatever it takes...
“I must be a mermaid, Rango. I have no fear of depths and a great fear of shallow living.

Messier 13 – the Great Globular Cluster in Hercules
Located in the armpit of the constellation Hercules, M13 is one of the best known globular clusters in the northern hemisphere. Discovered by Edmond Halley (for whom the comet is named) in 1714 and cataloged by Charles Messier in 1764, it’s a cluster of several hundred thousand closely grouped stars. The stars are about 100 times more densely packed than in our area of the galaxy. It’s estimated to be approximately 22.2 thousand light years away, with a diameter of 145 light years. The galaxy in the upper right is NGC 6207, which is about 30 million light years away and 34,000 light years across.
Globular clusters reside in the halo of a galaxy as opposed to the disk and are bound together by gravitational forces. There are about 150 known globular clusters in the Milky Way, with an estimated 20 more hidden by dust lanes. They are generally comprised of very old stars, and M13 is estimated to be 11.65 billion years old. The process in which globular clusters are created is largely unknown, but it’s hypothesized that they originate from areas of starburst activity and interactions between galaxies. There is no known active star formation in any of theses clusters, but due to the proximity of the stars collisions occur, and new stars are created. These new stars are called “blue stragglers”, some of which may be seen in the photo. The proximity of the stars (on average about one light year apart) also creates many binary star systems (think Tatooine), but due to the age and makeup of the stars there are very few with planets.
This is about 3:15 hours of exposure.

![I recently took a roadtrip through New Mexico and Arizona. This shot was taken in Colossal Cave State Park outside of Tucson after I'd pitched my tent for the night. I was absolutely entranced by the giant Saguaro cactus that litter the landscape. I think this shot captures some of the magic that I felt being there.
30 seconds is the longest shutter speed on my [very old] camera, but there was just enough light coming over the horizon to keep the ISO relatively low for this shot.](https://gimgs.nohat.cc/thumb/f/350/i-recently-took-a-roadtrip-through-new-mexico-and-arizona-this-shot-was-taken-in-colossal-cave-state-park-outside-of-tucson-after-i-d-pitched-my-tent-for-the-night-i-was-absolutely-entranced-by-the-giant-saguaro-cactus-that-litter-the-landscape-i-think-this-shot-captures-some-of-the-magic-that-i-felt-being-there-30-seconds-is-the-longest-shutter-speed-on-my-very-old-camera-but-there-was-just-enough-light-coming-over-the-horizon-to-keep-the-iso-relatively-low-for-this-shot--unsplash1pWGcPucwZc.jpg "I recently took a roadtrip through New Mexico and Arizona.
