The bright star just off-center is Polaris, which is surrounded by Integrated Flux Nebulae (IFN) named the Polaris Flare, discovered in 1984 by Heiles (Panopoulou et al. 2015: doi.org/10.1093/mnras/stv1301). Yildun, the brightest star in the lower right-hand corner, is the next star in the 'handle' of the Little Dipper.

This is the first version of this image. A new version at www.flickr.com/photos/frame_maker/14175453777/ contains reflections of the boat, pilings, and sky. I just learned how to create reflections in Photoshop. I'd appreciate any comments on which version you prefer, as well as suggestions for improving the reflections.
Where I find beauty, others often see something that does not belong in our otherwise clean and orderly world, and must be erased. This abandoned tug boat, the Polaris, is officially considered a "public nuisance." It ran aground near Lone Tree Point in Rodeo, California on the night of April 14, 2013. Because the location was in the East Bay Regional Park District, the District issued a notice to remove the boat, but the owner did not comply. After weeks of negotiation the vessel was moved off the rocks to a nearby marina, D&R Marine. The vessel is now considered a "public nuisance" and the California State Lands Commission has been authorized to remove it.

F/V Polaris at Fishermen's Terminal, one of the hundred-years-old boats built in Seattle from old-growth fir I keep coming back to. Drawn with a rough carpenter's pencil I picked up on the bike path and painted with watercolour on the spot, which the rain mainly washed away, so had to add again at home.

Polaris & ses nébuleuses sombres

Aujourd’hui, je vous fais découvrir les nébuleuses sombres qui accompagnent l’étoile polaire.
Cette étoile sert depuis des millénaires comme point de repère entre autre pour la navigation. Elle nous sert aussi à nous aligner pour nos montures équatoriales puisque toutes les constellations tournent autour de Polaris.
Que viennent faire les nébuleuses sombres dans cette histoire ?
Elles sont présentes autour de notre étoile polaire. En anglais, elles sont appelées IFN pour « Integrated Flux Nebula ». Elles sont principalement composée d’hydrogène moléculaire et d’hélium.
Cependant, ce n’est pas aisé de pouvoir les photographier. D’une part, comme leur nom l’indique, elles sont obscures.
Ce sont des nuages denses qui absorbent la lumière des étoiles en arrière plan.
D’autre part, au moment de la prise de vue, elles sont invisibles. Très pratique me direz vous… Même constat au moment de l’empilement, il n’y a que le traitement qui permettent de les mettre en valeur.
A titre d’exemple la tête de cheval (IC434) dans la constellation d’Orion fait partie des nébuleuses sombres les plus connues.

This is the is a composite made up of the same six, 10-minute exposures. I adjusted the white balance and also left in the boat traveling across the horizon,
I'm honest not sure which white balance I like better, I like both for their own respective reasons. Let me know what you all think.
The boat actually really surprised me that night: all of a sudden there was this insanely bright light in front of me which slowly moved across the rocks. It almost looked like someone was walking on the rocks holding a flare or something. It was almost blinding to look at, however it wasn't casting a significant/ noticeable amount of light on me. I finally assumed it was a boat once it started moving faster and moved out past the rocks.

I took this picture in the middle of Puszcza Notecka in Poland, the closest proper dark sky area near my home. The dark-brownish could to the right is nothing else but the end of the Milky Way's arm that was cought in the frame. I really like this smeared effect it made. Whole exposure lasted for 15 minutes.
Picture taken with Samyang 12mm F2.2. I am pretty satisfied with the results I got from this unexpensive piece of gear.
