The Ant Nebula (Mz 3)

H-alpha - red plus 25% blue
NII - green but with shadows and mid-tones de-emphasised
OIII - blue
SII - red plus 25% green
SIII - stars

Strengths of the various contributions were driven partly by aesthetics but mostly to emphasise structure. Thanks to the Hubble Legacy Archive for providing the data to play with.

Beautiful sunrise over a frozen lake in Northeast Ohio. The sun was just peaking over the horizon lighting the clouds & contrails and reflecting off the lake's ice. The trees are silhouetted by the red hue of the sunlight.

Celestial Motions, Eclipses & Transits

Postby abem » Sat Jun 09, 2012 7:27 pm

The sky has been a busy place these past few weeks!

It was amazing to have a solar eclipse and a venus transit just over two weeks apart. Since I photographed both events from the same location, I thought it would be interesting to superimpose the two images to visualize the motion of the path of the sun over those 16 days.

The Sombrero Galaxy and a Swarm of Globular Clusters
http://www.pbase.com/rolfolsen/astro_photography
Copyright: Rolf Wahl Olsen

Orbiting the Sombrero galaxy is one of the largest known populations of globular clusters, containing up to 1900 members. In comparison our own Milky Way galaxy has only around 150-200 such clusters.
Highlighted in this image are 136 of the Sombrero's brightest globulars, ranging in magnitudes from 17.5 to 22+. Some of these globulars are very large and one is classified as a separate Ultra Compact Dwarf galaxy, SUCD1, the closest known example of such an object. It is not known how the Sombrero amassed such a large number of globular clusters. This is normally a more typical feature of large elliptical galaxies. For example up to 12,000 globular clusters are orbiting the giant elliptical galaxy Messier 87.
In the background numerous distant galaxies can be seen, many of them clumped together in groups. Also, what appears to be a faint tidal tail of the Sombrero is visible near the middle of the bottom edge of the image (between globulars #82 and #99). This is likely an ancient remnant trail of a captured dwarf galaxy.

(Including list with details of all 136 globulars)

Obscured Globuar Cluster Terzan 9 and Surrounds
http://www.pbase.com/rolfolsen/astro_photography
Copyright: Rolf Wahl Olsen

Link to high resolution version: http://www.pbase.com/rolfolsen/image/144014839/original

This image shows the heavily obscured globular cluster Terzan 9 in Sagittarius. Terzan 9 lies within the Milky Way's central bulge at a distance of 23,000 light years. The cluster is significantly reddened and heavily obscured by the massive interstellar dust clouds in the direction of the Milky Way centre. A solid dark dust lane nearly covers the cluster but still its faint combined glow of thousands of stars reach us from a place near the galactic centre.
Also visible in the upper right corner is the small bright blue planetary nebula IC4653 at a distance of 10,500 light years. A little below IC4653 another tiny purple planetary nebula is seen; ESO 521-14 which at 27,000 light years lies much further away than even Terzan 9.

After the successful soccer game Germany vs Netherlands I recognozed some bright clouds in the north. So I started to take photos with a lake in the front (Einfeler See, Neumünster, Germany).

The McMath-Pierce solar telescope is the world's largest solar telescope, and the world's largest unobstructed-aperture optical telescope with a diameter of 1.6 meters. Permanent instruments include a dual grating spectrograph capable of extended wavelength coverage (0.3-12 microns), a 1-meter Fourier Transform Spectrometer for both solar and laboratory analysis, and a high-dispersion stellar spectrometer.

Henize2-111 and Alpha Centauri
http://www.glitteringlights.com/
Copyright: Marco Lorenzi

Blazing brightly in the southern sky, the supergiant binary Alpha Centauri is the host of an expansive starscape sprinkled with numerous deep sky objects in this telescopic view. The most visually striking of its retinue of glittering jewels is the exotic and unique planetary nebula Hen 2-111, which is one of 468 planetary nebulae that were catalogued by Karl Henize in 1967. The main central part of Hen 2-111 is a bright peanut shaped core that measures only 29 x 15 arcseconds. However, its most visually striking aspect is a faint giant ionized halo that spans 10 x 5 arcminutes! This extreme structure was discovered by B. Louise Webster in 1978 in deep photographic plates taken with the (at the time) Anglo-Australian Observatory. Also barely visible in the glare of Alpha Centauri is a round broken roughly circular shell, which can be seen to the north of the halfway point between Alpha Centauri and Hen 2-111. This is the supernova remnant G315.4-0.3, which was discovered in a radio continuum survey by Anne Green in 1974 and identified as a supernova remnant in 1975. However, its extremely dim optical shell was discovered recently in 2011 in a search for new supernova remnants in SuperCOSMOS Ha Survey (SHS) images by Milorad Stupar and Quentin Parker.
