I had to take my crack at the Orion Nebula, I've been waiting all summer for it and stayed up 'till 3:00 AM to get some usable sub frames. Pardon the typo, I know it's really M42.

Mars from this apparition 2011-2012, Here is a collage of less then a third of captured images showing the size differences and the North Polar Cap decreasing in size in almost a year time lapse as it got closer and thru leaving us again until 2014. Opposition is the closest the planet got to earth.

All Four Naked-Eye Galaxies Over La Silla
Copyright: Iair Arcavi This is an excellent time of year to see all four naked-eye galaxies from the southern observatory of La Silla. From left to right: The Large and Small Magellanic Clouds, the Milky Way and the Andromeda Galaxy are all visible in this wide field panoramic. Like many observatories, light pollution is slowly closing in also on La Silla, with the most prominent luminance coming from the city of La Serena, located some 90km to the southwest of the observatory. Nevertheless, La Silla skies remain one of the most pristine in the area, making the site home to several telescopes, some of which can be seen in the image. These include the ESO 3.6m Telescope, the Swiss and Danish Telescopes, mostly searching for exoplanets, and the New Technology Telescope (NTT) which will be spending the weekend classifying potential new supernovae.

Sun in the day to hit the autumnal equinox along the silhouette of the medieval castle. Remains have been dated to the Late Bronze Age in this mountain island in the middle of the Vegas Altas Guadiana River, although it probably already settled the first humans arrived in the area after crossing one of the few natural fords sometimes mighty river . Today, this river vertebra the economy of the region, with a network of reservoirs and canals that allow the development of intensive agriculture: tomatoes, corn, rice, fruit ... Hernán Cortés was born here.
El Sol en el día que llegará al equinoccio de otoño junto a la silueta del castillo medieval. Se han datado restos del Bronce Final en este monte isla en medio de las Vegas Altas del río Guadiana, aunque probablemente en él ya se asentaron los primeros humanos que llegaron a la zona, tras cruzar uno de los escasos vados naturales del a veces caudaloso río. Hoy día, este río vertebra la economía de la región, con una red de embalses y canales que permiten el desarrollo de una agricultura intensiva: tomate, maiz, arroz, frutales... En las faldas del castillo nació Hernan Cortés.

WR134

Hello everybody,

I found the great APOD from 2012 June 21 by Don Goldman and decided to try this object with my 12" Newtonian and 24 hours exposure time.
A large version of this image you will find at www.wittich.com.
Best wishes

I spent the night of September 14/15, 2012 at GMARS (Goat Mountain Astronomical Research Station)—the dark sky site of the Riverside Astronomical Society near Landers, CA, and while astronomers were all busy photographing the wonders of the cosmos with fantastic high-tech telescopes, I was busy photographing their fantastic high-tech telescopes! Here's a shot of Alex McConahay's observatory; the centerpiece is a Meade 10-inch f/4.5 Newtonian, aimed straight up toward the zenith. Above the roll-off-roof structure appears a sky full of stars and the hazy band of the Milky Way. Photo Details: Nikon D700, AF-S Nikkor 14-24 f/2.8G ED lens at 14mm, ISO 3200, 15 sec at f/4.5.

It is during September--when the moon is nowhere around and were under a pristine dark sky--that we can see both the Milky Way and the zodiacal light, the dusty disk of our solar system that is back lit by the sun. Here, looking east over the Borrego Valley-- Californias first and only International Dark Sky Community--during the first glimmers of dawn we can see the winter Milky way (to the upper right) and the zodiacal light streaming upward from the lower center. The bright star in the zodiacal light is Venus.

Equinox dawn

Post by lgym » Sat Sep 22, 2012 6:45 pm

Equinox dawn 2012-09-22 In bigger size: http://users.atw.hu/egbolt/equinox_dawn_20120922.jpg

Panoramic image taken at Márkó, Hungary at the small chapel by the village edge. Cirrus clouds were present and they enhanced the colours of the stars with creating hazy aureoles around them, it was very spectacular at Orion. Bright Venus - also with a hazy aureole - is above the red clouds of the horizon, Leo also sticks its head out of the cloud - the blue hour quickly became red and purple as the sun got closer to the Eastern horizon began to illuminate them. I hope everyone had a nice equinox sky!

Atoms for Peace Galaxy (NGC 7252 / Arp 226) - and some very distant globular clusters
http://www.rolfolsenastrophotography.com
Copyright: Rolf Wahl Olsen Click here for a larger image
Click here for a large crop of the galaxy itself

This intriguing galaxy is located in Aquarius at a distance of 220 million light years. The outer loops and especially the long ejecta streams are very faint, but the core shines relatively brightly as a stellar point. The combined magnitude of the system is 12.7 within an area of approximately 1.9 x 1.6 arc minutes.
Within the swirls of the collision are numerous bright knots some of which are young ultra-luminous globular clusters containing up to a million hot blue stars each. Several hundreds of these exist near the core of the galaxy.
It is known that giant elliptical galaxies often contain a vast amount of globular clusters, for example the galaxy M87 in Virgo contains over 12,000 globulars. These are thought to have been acquired during past mergers with other galaxies which ultimately formed the elliptical galaxy itself. Still, the number of globulars around giant elliptical galaxies far exceeds the expected number that could be acquired from mergers alone. In this context it is therefore interesting that the collision currently happening in the Atoms for Peace galaxy seems to have triggered the creation of fresh young globular clusters, in addition to any ordinary globulars that would already have been orbiting the merging galaxies. The creation of new globulars during collisions could explain how giant ellipticals amass such a massive number of globulars over time.

This image likely represents the most distant globular clusters imaged with amateur equipment, being 220 million light years away. This is only possible due to the extremely high luminousity of these young globulars. To illustrate the luminousity of these clusters one can compare with globulars in our own Milky Way. The absolute magnitude M of an object can be calculated as follows, given its apparent magnitude m and luminosity distance DL in parsecs:

M = m - 5(log10(DL) - 1)

For very large distances, the cosmological redshift complicates the relation between absolute and apparent magnitude, but for the Atoms for Peace galaxy it is probably safe to ignore this given that 220 million light years is not a very large distance in cosmological terms.
The brightest of the globulars in this image is [WSL93]3, the bright knot immediately to the left of the galaxy core, with a magnitude of 17.86. This translates to an absolute magnitude of -16.28 as per the equation above. Omega Centauri, the largest known globular cluster of the Milky Way, has an absolute magnitude of -10.26 and from the logarithmic nature of the magnitude scale it thus follows that [WSL93]3 is 256 times more luminous than our own Omega Centauri - a truly impressive sight if it was placed in our own galaxy.
