Dog Star [C_065586]

For reason's I'm not entirely clear about, this is my 4th most viewed photo on Flickr. Not my Astronomy Photographer of the Year, 2010 photo, or the 2012 runner-up photo. And not my favorite photo. If you're dropping by, please let me know how you got here!


Why are the stars all bloated? Did I use my Bump Up the Stars trick?


Nope. This resulted when thin clouds scattered the starlight. One thing that happens as a result is that the star color is more noticeable. Notice the blue stars in the belt of Orion, and a very red star Betelgeuse, ok, call it orange, near the top.


The super fat star is "Sirius" and it's called the Dog Star because it is in the constellation Canis Major (Big Dog). Sirius is the brightest STAR in the night sky - although on this night the brightest object was Jupiter until near dawn when Venus rose.


By the way, "Sirius FM" logo is a dog for reasons which are probably now obvious.


While I did see meteors, I haven't been able to notice any in my hundreds of frames. Gemini - apparent radiant point for the Geminid meteor shower can be found by following a line from Rigel (lower right star in Orion) through Orion's belt and Betelgeuse.


NOTE: This shot was quickly processed on a laptop. As some of you may know the result on a laptop varies quite a lot depending on your viewing angle and ambient light conditions.
