26 West, the Moon and Jupiter
Taken at the Pisgah Astronomical Research Institute in Rosman, NC. A 10 second exposure on a tripod shows 26 West, a radio telescope that was once instrumental during the Apollo program for ground to space communications. A young man in the corner is composing his own shot of the dish and has lit up the area around himself and to some extent the underside of the dish.

M51, aka The Whirlpool Galaxy
Hi folks,
The aim was a natural looking colour balance, a little 'sparkle' from those young blue stars, clarity of the dust lanes and the addition of enhanced hydrogen emission nebulosity. The thumbnail below links to an image is 5651 pixels wide (50% scale and about 6.4MB).
The underlying HST data has previously been used in an APOD but I hope that this rendition is sufficiently different to merit consideration.

The Dolphin Nebula (Barnard 252)
http://www.rolfolsenastrophotography.com
Copyright: Rolf Wahl Olsen Here is my latest image - a quick 2 1/4 hour intermezzo in between the regular multi-night data gathering sessions.
There are just so many of these lovely and quite unknown dark nebulae around the Milky Way plane!
Link to large image
Link to full resolution image (6MB)
About the image:
Located among the incredibly dense star fields of Scorpius lies a beautiful little dark nebula; Barnard 252.
There appears to exist very little, if any, information about this striking absorbing cloud, and it has no popular name.
I think it bears a strong resemblance to a jumping dolphin so I call it The Dolphin Nebula.
This interstellar cloud is sufficiently dense to completely block the light from thousands of background stars in the direction towards our galactic centre.
There exist many dark patches such as this one and the most famous is without doubt the Horsehead Nebula in Orion. Another and much larger example, visible to the naked eye when away from city lights, is the large dark patch near the Southern Cross known as the Coalsack Nebula.
These clouds are full of tiny dust particles, each less than a micrometre in size. Optical wavelengths are easily absorbed by this dust and therefore the nebulae appear dark against any background light. However, radio and infrared wavelengths can penetrate the clouds and allow a peek inside where star formation often occurs.
In the early 1900's the american astronomer Edward Emerson Barnard complied a catalogue of dark nebulae by studying his many photographs of the Milky Way. Barnard was also an avid visual observer and discovered 15 comets, Jupiter's small moon Amalthea and Barnards Star the second closest star to our solar system. He also made fleeting observations of so-called 'spokes' in Saturn's rings; a mysterious phenomenon only confirmed much later when the Voyager 1 space probe passed Saturn in 1980.

NGC7000 The North American and IC 5070 The Pelican Nebulae
http://www.astrosirius.org/
Located in the summer constellation of Cygnus, the North American Nebula (NGC 7000 at the middle left of this image) and the Pelican Nebula (IC 5070 on the right) form a complex of hydrogen emission nebulae located just a few degrees east of the first magnitude star Deneb.
The North America Nebula and the nearby Pelican Nebula, (IC 5070) are in fact parts of the same interstellar cloud of ionized hydrogen (H II region). Between the Earth and the nebula complex lies a band of interstellar dust that absorbs the light of stars and nebulae behind it, and thereby determines the shape as we see it. The distance of the nebula complex is not precisely known, nor is the star responsible for ionizing the hydrogen so that it emits light. If the star inducing the ionization is Deneb, as some sources say, the nebula complex would be about 1800 light years distance, and its absolute size (6° apparent diameter on the sky) would be 100 light years.
The Pelican is much studied because it has a particularly active mix of star formation and evolving gas clouds. The light from young energetic stars is slowly transforming cold gas to hot and causing an ionization front gradually to advance outward. Particularly dense filaments of cold gas are seen to still remain, and among these are found two jets emitted from the Herbig–Haro object 555. Millions of years from now this nebula might no longer be known as the Pelican, as the balance and placement of stars and gas will leave something that appears completely different.

Miky Way Arch Over Beijing
Image Credit & Copyright: Zhan Xiang
City lights hidden the stars, but on top of the light pollution, the starry sky is out there, waiting for someone to watch. If we can stay away from city lights, we can be more close to the stars. In the early morning of May 3, 2014, Zhan Xiang from Beijing Planetarium climbed a mountain and took this picture. Downtown Beijing is on the east of the mountain, so the Milky Way is just over the city. In order to reduce the overly bright city lights, Zhan Xiang shook the black card. This panoramic picture was taken by Canon 6D + 24 mm lens, ISO 3200, f/2.0, 10 seconds exposure, 9 photos combined.

Description:
Image of the comet C/2014 E2 Jacques on April 26, 2014 showing a great increase of brightness with respect to I took only eight days before, increasing in this short time from 9 to 8 magnitude. About its morphology is similar but its coma diameter has doubled from 4' to 8'. The comet keeps a begin of tail toward southeast but has only a few minutes length.
