NGC 6188 (aka The Fighting Dragons of Ara) by SAO student Suavi Lipinski.	As reported by the ABC, this image was projected onto the William Jolly Bridge in Brisbane as a part of "Stargazing Live, 2018".
Star trails by Sharon Harnett	"This image was composed of 177 images taken from 1123pm on 30 March 2012 to 1239am 31 March 2012. The image was taken looking to the south from my backyard in suburban Canberra. The images were taken with a Canon DSLR 400D, 10mm lens, at ISO 800, f3.5, with a 24 second exposure. I then stacked the 177 images using StarStax to form startrails."
Aurora Australis by Alex Cherney	"After chasing it for more than two years, I was finally rewarded with two displays of Aurora Australis within a week, visible from the southern tip of Mornington peninsula, not far from Melbourne. The nights were warm an clear and the Moon was not in the sky either - I could not have asked for better conditions." (Alex's gorgeous image also made it to APOD, and you can view the animated sequence on vimeo.)
NGC7293 by Lynn van Rooijen-McCullough	"NGC 7293 (Helix Nebula): a difficult target, lying just above the horizon, even in France. Taken with C11, Hyperstar 3 @ f/2, Starlight Xpress H18, Astronomik Ha & S[II] filters & Sloan g-r-i photometric filters. Not the usual combination, but I was using the Sloan filters for other work and decided to continue with them. 5.5 hours & 68 images total."
NGC6914 by Lynn van Rooijen-McCullough	"NGC 6914, an area of emission & reflection nebulae near the IC 1318 region. The illuminating stars of the nebula belong to the Cygnus OB2 association. Taken with C11, Hyperstar 3 @ f/2, Starlight Xpress H18, Astronomik Ha & S[II] filters & Sloan g-r-i photometric filters. About 4 hours & 52 images total."
Orion Nebula by Michael Pachomski	"Orion Nebula, M42 and M43, imaged with a Meade Classic LX-200 10-inch Schmidt-Cassegrain telescope. Using a Lumicon deep sky filter and a Canon T2i DSLR camera with mixed ISO's of 800, 1600, 3200 and 6400 taken at 20 second exposures. Images were stacked in Deep Sky Stacker with post processing in GIMP for a total exposure of 14 minutes. Photos taken with on the University of New Hampshire Observatory grounds, Durham, New Hampshire, USA."
M31 by Marek Cichanski	"SBIG ST-8300M monochrome camera. The camera uses the same Kodak 8300 CCD chip as the QSI camera. I shot my unbinned R, G, and B images through a set of Orion 2" color filters, mounted in an Orion filter wheel. It was a dark-moon weekend at the end of September, 2011 - the occasion for this year's California Star Party (`Calstar')."
Eagle nebula by Marek Cichanski	"This image is the product of a week of data acquisition at the end of July/beginning of August, 2011. A group of friends and I make a yearly pilgrimage to Lassen Volcanic National Park, northern CA, USA. The image consists of a few hours each of: R, G, B, and H-alpha filters using an Orion ED80 semi-apo refractor, 80mm, f/7.5. I borrowed a friend's QSI 583 monochrome CCD camera with a built-in LRGBHa filter wheel. I was using a pretty simple `Sirius' mount, also from Orion, and one of their guiding setups - a `StarShoot' autoguider camera. Acquisition, autoguiding, and dithering were done with MaximDL. I did my image calibration and processing in Pixinsight."
Jupiter by Jim Katsifolis	17 Oct 2011: "If you look closely at the attached image you can see Ganymede passing in front of Jupiter at bottom left, and Io just to the right of Jupiter. I used a Thorlabs DCC 1645C USB camera at the primary focus of a Meade 8" SCT, and took 2000 frames at 21 frames/sec which was processed with Registax 5.1."

Comet Holmes - November 9, 2007; by Tim Hunter	Taken 135 mm f/3.5 lens on a Nikon D100 camera using a 5 second exposure and ISO 800. The numbers next to the bright stars represent their Mag (v) as listed in MegaStar 5.0. Notice how much the comet has grown in size since my images of October 24, 2007.
Time series of Minor Planet 28736; by David Higgins	I was undertaking time series images of Minor Planet 28736 when I noticed it was traversing a stellar void. I co-added 44 images in the series resulting in the equivalent of an approx 3 hr exposure of this region of space revealing some detail in what is classified a dark nebula (LBN 19, LDN 188 or LDN 175 - not sure which one since the star charts put all 3 overlapping each other). The brightest pixel of the brightest part of the nebular measures magnitude 20. The image is 25' x 18'). The 'dotted' line is my target Minor Planet.
Phases of Moon; by Tim Hunter	This is an animated gif of the Moon phases from day one through day 27. Individual images of the Moon were taken daily in the Spring of 2005 with a Meade LPI camera on a Celestron 2.4 inch f/10 telescope. The images were collected over approximately two Lunar cycles.
Comet Holmes Wide Angle; by Tim Hunter	Taken on Wednesday evening October 24, 2007 at 9:00 pm local time with a 15 mm f/4 lens on a Nikon D100 digital camera with a 10 second exposure at ISO 800. Cassiopeia is the upside down chair above and left of center. The green fuzz ball in the upper right corner is the Andromeda Galaxy (M31) and the nearly full Moon causes an unwelcome glow coming from the upper right hand corner. Perseus is just below center, and the comet is circled. Note the Pleiades near the lower right hand corner. Two radio towers are partially seen in the lower left hand corner.
Comet Holmes 50mm; by Tim Hunter	Taken on Wednesday evening October 24, 2007 at 9:15 pm local time. It zooms in on Perseus which is partially shown just to the right of center. The image orientation is the same as above. This is a 10 second exposure with a 50 mm f/2.8 lens on a Nikon D100 digital camera at ISO 800. The numbers next to the bright stars represent their Mag (v) as listed in MegaStar 5.0. The comet is currently an easy naked eye sight. It wouldn't be such a big deal as it has no tail except that it is a gorgeous sight through a telescope, and it suddenly brightened a millionfold.
