What?
|
Stayed up Monday night and shot a few targets. This one is the Orion Nebula, Horsehead Nebula and surrounding area. Shot with the astro cam, filters and Canon 135 lens. No telescope. I'm excited about this new camera. It's incredibly sensitive. This shot is only 12, 2 minute exposures with no calibration frames. Can't wait to get many hours worth of exposures.

I'm getting a little better at the image Inquisition and processing.

The second one is the Rosette nebula, right? Also spectacular.

Anyone see the meteors last night? I didnt... stayed up until 220am spent 30 minutes out, nothing. Did hear a couple of owls getting laid or having a party or something... and a fox.

It seems like the meteor showers are always "most visible between 3am and sunrise" or something like that. I'm not awake at that time. Not to mention that to have the best view of them, you need nice dark skies which I don't have. So I'd have to get up and then drive an hour or two or three to find dark skies. Maybe someday, but not today.

 If I wanted to get serious about it some of the darkest part of the state is about an hour drive from me. No telescope so my magnified observation is limited to breaking out the target rifles with 20x and 32x scopes  Needless to say, that is "at home in yard" observation only. Gotta love country living.

Yeah, beautiful!!!!! What I really liked about this image was that MANY years ago in the late 80’s, my dad took us to see a friend of his who built an amateur observatory(seemed purdy darn professional to me) to peek at the sky. He was at a level that he was one of five amateur’s invited to Hawaii for the 86 Halley’s Comet. Anyway, he showed us our sister galaxy with just a pair of binoculars. I am still amazed that there are folks that still think we are the only rock in space with life. Then again I have an aunt who thinks the earth is only 10K years old.........religion

Stunning. THe Great Red Spot is approximately the size of the Earth. Sure makes you wonder.

Wow, the detail is incredible. Each side of that hexagon is over 9000 miles.

Incredible. The formation doesn't jive with my understanding of fluid motion but then what do I know.
"...One hypothesis, developed at Oxford University, is that the hexagon forms where there is a steep latitudinal gradient in the speed of the atmospheric winds in Saturn's atmosphere.[20] Similar regular shapes were created in the laboratory when a circular tank of liquid was rotated at different speeds at its centre and periphery. The most common shape was six sided, but shapes with three to eight sides were also produced. The shapes form in an area of turbulent flow between the two different rotating fluid bodies with dissimilar speeds.[20][21] A number of stable vortices of similar size form on the slower (south) side of the fluid boundary and these interact with each other to space themselves out evenly around the perimeter. The presence of the vortices influences the boundary to move northward where each is present and this gives rise to the polygon effect.[21] Polygons do not form at wind boundaries unless the speed differential and viscosity parameters are within certain margins and so are not present at other likely places, such as Saturn's south pole or the poles of Jupiter. Other researchers claim that lab studies exhibit vortex streets, a series of spiraling vortices not observed in Saturn's hexagon. Simulations show that a shallow, slow, localized meandering jetstream in the same direction as Saturn's prevailing clouds is able to match the observed behaviors of Saturn's Hexagon with the same boundary stability.[22] Developing barotropic instability of Saturn's North Polar hexagonal circumpolar jet (Jet) plus North Polar vortex (NPV) system produces a long-living structure akin to the observed hexagon, which is not the case of the Jet-only system, which was studied in this context in a number of papers in literature. The north polar vortex (NPV), thus, plays a decisive dynamical role to stabilize hexagon jets. The influence of moist convection, which was recently suggested to be at the origin of Saturn's north polar vortex system in the literature, is investigated in the framework of the barotropic rotating shallow water model and does not alter the conclusions.[23]

Thanks for the explanation, very fascinating. 9,000 miles is impressive considering the U.S. is approx 2,680 miles wide.
 A good program found on Amazon Prime if anyone is interested  Sent from my iPhone using Tapatalk
