Storm Over the Caribbean by Radical Retinoscopy, on Flickr

A distant summer storm is seen in the Caribbean Sea off the coast of Grand Cayman Island. Three distinct lightning strikes can be seen reaching the sea from the left thunderhead. It was amazing to capture such a vivid display in a single twenty second exposure. The photo was taken with a Canon T2i and a Canon 8-15 mm f/4L lens at (f/4.0., 13 mm, ISO 400).

M33 the Triangulum galaxy is a spiral galaxy ~3 million light years distant in the constellation Triangulum.
This is a widefield of M33, the Triangulum galaxy. This was imaged using the Orion 80mm EON with a field of view of 1.56° x 2.07° and the Explore Scientific 127mm Apochromatic refractor for luminance and enhance detail within the galaxy.
Luminance 48min, Red 60min, Green 60min, Blue 60min and 60min of Ha using the Orion 80mm EON
An additional 8 minutes luminance (x15) was imaged with the Explore Scientific 127mm APO.

http://cdn.astrobin.com/images/thumbs/3 ... 0Woods.jpg NGC 1365, also known as the Great Barred Spiral Galaxy, is a barred spiral galaxy about 56 million light-years away in the Southern Hemisphere constellation Fornax. The core is an oval shape with an apparent size of about the same apparent size as the full moon. The spiral arms extend in a wide curve north and south from the ends of the east-west bar and form an almost ring like Z-shaped halo.

In February 2013, observations using the NuSTAR satellite have found out that the central supermassive black hole of NGC 1365, measured to be about 2 million solar masses in mass, is spinning at almost the speed of light.

Hundreds of galaxies litter the background of this image. No noise reduction was performed in order to maintain these faint fuzzies.

Rochester Panel

http://www.ancientskys.com/Anasazi-ruin ... 3_1-X3.jpg Extensive petroglyph panel in the San Rafael Swell outside of Emery Utah. There are at least a hundred petroglyphs on this panel, mostly Fremont in origin. This is one exposure with the winter Milky Way in the background, the rocks were illuminated with a flashlight for a few seconds. I find the most interesting feature is the arch in the middle reminiscent of a rainbow or perhaps our Milky Way Galaxy.

View in full size to fully appreciate the extensiveness of this panel

Peek-A-Boo Moon

I call this Peek-A-Boo moon because at the bottom you can see the tip tops of some mountains and crater rims "peeking" up out of the darkness from beyond the terminator where the sunlight is just grazing their tops. I was also very happy with how well the subtle color variations came out in the maria, and in the ray systems.

MBM 54 is a faint molecular cloud located about 900 light years from our solar system in the outer regions of our galaxy. These types of clouds are found at high galactic latitudes (parts of the sky away from the plane of our Milky Way Galaxy) and are often referred to as galactic cirrus clouds or more commonly the "Integrated Flux Nebula". These clouds are very faint and quite tricky to photograph. The IFN was first discovered in 1984 by the IRAS infrared satellite. In 1985, astronomers Magnani, Blitz and Mundy surveyed the IFN and developed their MBM catalog of 56 high galactic latitude molecular clouds. MBM 54 is one of the closer of these IFN clouds.

Also shown in this image are numerous background galaxies including the prominent edge on spiral galaxy NGC 7497 (just left of the center of the image). At a distance of 59 million light years, this galaxy is over 60,000 times farther from us than the foreground MBM 54 clouds.

Thanks for looking!

Messier 26

Not so impressive as M11, however M26 is a very nice Open Cluster lying in a crowded starfield in Scutum.
Taken from Argentine Pampas 110 km north of Buenos Aires, three new Moons ago...

Hidden Gems of the Cone Nebula

>> Please view the larger mouse hover image here.

Presented below is an optical image of the Cone Nebula by Chuck Manges with a hoverable infrared image from NASA's WISE mission processed by myself. Many hidden stars are revealed by infrared observation and it is fun to swap back and forth between the two and find the hidden gems shrouded completely by dust.

Optical image is Copyright Chuck Manges
Infrared image credit: NASA, WISE, IRSA. Processing by Judy Schmidt
Original size (3000 pixel) images are here and here.

For more information and a widefield view of the WISE image, see here. An uncropped thumbnail view is also below.

I’d like to share my narrowband image of Messier 16, the Eagle Nebula. I do most of my astrophotography from under the light dome of Melbourne, Australia. My observatory is located about 15 km from the CBD, and is situated in a red zone classification of light polluted skies. As a result, I tend to image in narrowband in an effort to cut through the murky skies above.

The scope used to acquire this image was a 10 inch RCOS f/9 Ritchey-Chrétien, using a SBIG STL-11000m camera, riding on an Astro-Physics AP900 Mount. 18 X 600 second subs were used to create the image.

Fine pictures, Geck.

There is a widefield image of the Cone Nebula region that reveals the optical counterpart of the strange structure in the lower right corner of the WISE image. Rolf Geissinger's widefield optical image is here.

Ann

Thanks, Ann. I did check for optical pictures of that area too just to see how it looked but it doesn't seem to have a common name and I'm not sure what the red glow from the infrared image is. The optical counterpart actually only vaguely resembles the infrared view once the two are overlaid to compare them. Looking at the two gives me an impression of its cavernous dimensionality.
