Lunar Eclipse over Maryborough Railway Station
Lunar Eclipse over Maryborough Railway Station, a grand station for a small regional Victorian town built during the gold rush days. As Mark Twain dryly observed on his visit in 1895: "A railway station with a town attached".

Full Moon over the Basilica of Don Bosco
http://stefanoderosa.com/
Copyright: Stefano De Rosa Please find above two images and a sequence of the Full Moon rising behind the Basilica of Don Bosco, located few kilometers from Turin, the evening of April 15, 2014.
In the second picture the Moon appears flattened as rising alongside the Basilica.
Images taken come 2.7 km away from the Basilica.
Best regards
Stefano

IC 4603 - The Turbulent Heart of the Scorpion
http://www.rolfolsenastrophotography.com
Copyright: Rolf Wahl Olsen Link to large image (4 MB)
Here is the latest image from my 12.5" f/4 scope. Data was gathered from early March and into April.
Interestingly, while the whole Rho Ophiuchi region is one of the most photographed in the sky there hardly exists any high resolution images of this; its colourful action packed core area.
About the image:
This image shows the core region of the Rho Ophiuchi Complex, centered around the prominent blue reflection nebula IC 4603. This is one of the nearest star forming regions and the intricacies of the dense interstellar dust clouds in the area provide a spectacular display of light and shade; the contrasting hues making this one of the most dramatic and colourful patches of the entire night sky.
Even the brightest parts of this dusty nebulousity is barely noticeable when viewed through large amateur telescopes. This deep exposure brings out the full splendour of the scene and shows the delicately swirling clouds like an expressionist painting on a giant interstellar canvas.
The bright star is 7.9 magnitude SAO184376 which is the main source of light for the blue reflection nebula. The contrasting red areas are primarily illuminated by the red supergiant star Antares, which lies just outside the field of view.
Antares has been referred to as the heart of the scorpion since antiquity, and we now know that it is one of the largest stars in existence.
The dense nebulousity blocks the usual sprawling star fields that are normally seen near the galactic plane. Instead the area is littered with dim reddish stars, which are typically very young T Tauri stars. Such stars are among the youngest visible stars with masses comparable to our Sun. Because they have only recently condensed out of the surrounding molecular clouds their core temperatures are not yet high enough for hydrogen fusion. Instead they are powered by heat released from gravitational contraction, which lasts until the star reaches a density where the fusion process ignites. For these stars this initial stage of stellar evolution takes approximately 100 million years. The process is typically much faster for blue giant stars which evolve and burn their hydrogen at a furious pace before exploding as brilliant supernovae.
Image details:

Lunar Analemma
Copyright: György Soponyai
This January my first Solar Analemma project was completed at the bank of river Danube in Budapest, Hungary:
![Image](https://farm4.staticflickr.com/3797/11815465285_58c30d7bf2_m.jpg)
I decided to go on this project by trying to capture the Lunar Analemma curve standing at the same location. I expected photographing the Moon during a whole Lunar month would require at least one or two years due to the terrible astro climate of my country, however the previous month I enjoyed the biggest luck in my life with the clouds.
The Moon needs 27.3 days for completing a revolution around the Earth (sidereal month) and completing a lap in the Analemma curve. But the period of Lunar phases are two days longer: Full Moons occur every 29.5 days (synodic month). By inspecting this image the difference between sidereal- and synodic month is evident: in every point of the Analemma curve the Moon has different phases in different laps.
![Image](https://farm4.staticflickr.com/3745/13893278724_b663b790f4.jpg)
In the foreground an office building, the Hungarian National Theater, the Palace of Arts and the Eastern pillar of Rákóczi Bridge are visible. This part of the river is frequently used by sight-seeing vessels to turn back to North towards the city center. I chose this foreground photo as the wave of the turning ship slightly resembles the mirrored curve of the Analemma.
The Lunar photos (a wide field and a closeup) were taken between 2014-03-15 and 2014-04-15 in every 24 hours 50 minutes and 48 seconds.

The Southern Cross and Coalsack Nebula
Large version on Flickr: https://www.flickr.com/photos/schmitzcory/13913808673/
The Coalsack dark nebula in Crux is an apparently massive and dense complex of dust and gas visible only in the Southern Hemisphere. It's a mind-blowing sight to see in dark skies, and appears as a gaping hole in the Milky Way, bordered closely by the beautiful constellation of Crux, or the Southern Cross.
Captured on a recent astrophotography trip 2014-03-30 in the Karoo Desert of South Africa, near the small town of Sutherland.
