Here is a picture of a lunar transit of ISS in daytime. We took this image early in last morning. While we were taking this, the sky was so bright so an intense post-processing is required to show the station clearly on this stacked image. Frames were taken from a video obtained by a Canon EOS 600D attached to a Celestron 125mm SCT. The bad quality is due to intense post processing to give more details. Here you can also find a video on youtube (you may need to watch twice to catch it)

Twice? I had to watch it three or four times at full screen and 1080p before I could catch it at the 5 o'clock position coming in. It's easiest to spot as it is leaving.
The raw material was taken during April, May and July 2013.
The picture consist of raw frames/subs taken with LX200ACF 16" and camera Atik 460ex mono.
Exposure time using Baader 1.25" filters:
Ha=42*5min,
OIII=42*5min,
Lum=28*5sec+16*60sec,
Red=66*30sec+35*2sec,
Green=72*30sec+17*2sec,
Blue=69*30sec+16*2sec.
The picture shown is a composite picture made of above mentioned narrowband/lum/color stacks.
The halo around NGC6826 consist of Ha and OIII information.
More and widefield pictures with higher resolution of NGC 6826 can be found on my web site.

A very ancient globular cluster about 12.2 billion years old. HST found white dwarfs in it as old as 13 billion. One such white dwarf has been found to be a binary star with a pulsar companion, PSR B1620-26 and a planet orbiting it with a mass of 2.5 times that of Jupiter. Nestled within the Rho Ophiuchi cloud complex in Scorpius this globular shimmers with gold as it is surrounded by interstellar dust and gas.
Caption: There was a half moon at this time and so the landscape in the background was lit up quite brightly. The sign in the foreground was lit by the headlights of passing road trains on the highway from Longreach to Winton in outback Queensland, Australia. Initially I was worried the headlights would ruin the photo, but they lit up the sign just nicely. Link: http://www.flickr.com/photos/mars73/8666295125/
Seen from an airplane in this anaglyph picture, a dense layer of coastal fog covers California's San Francisco Bay in the morning just after sunrise. The top of the fog forms waves that look a bit like the surf on a beach. Mount Tamalpais, Lucas Valley and Burdell Mountain are visible in the distance.
This is an anaglyph 3D picture; use red-cyan or red-blue glasses to view it.
When you stand outside on a sunny day, the antisolar point - the direction opposite of the sun - is easy to find: just look for the shadow of your head. When you are flying in an airplane at high altitude, then you won't be able to spot the plane's shadow, but if you are flying over a city, you can still see the antisolar point: it is the spot where street signs, car license plates and other retroreflecting objects glow brightly because they reflect the sunlight directly at you.
Here the cluster of bright lights on the ground is crossing highway 14 east of Santa Clarita, California (the plane is traveling right to left).
There is a very bright supernova happening at M74 galaxy and was recently discovered by Lick Observatory. This morning at 01:45UT i made this observation of the SN from my robotic observatory at Nea Magnisia Thessaloniki. At the time of the observation, the explosion had a magnitude of 12.4Mag and its of type II. The image was made with a 12" Catadioptric reflector and a CCD Camera.

Though APOD has featured many spectacular views over the years of Comet Hale-Bopp, here’s one from a little different viewpoint- the mirror’s eye view. For this picture in 1997, the 35mm film camera with a 50mm lens was mounted above the mirror of my 18” Dobsonian-mounted telescope, aimed out past the secondary mirror. In silhouette on the left, I manually tracked this time exposure, in order to record the blue ion and the white dust tails, which were clearly visible to the naked eye. While waiting impatiently for Comet ISON, I find myself reviewing Hale-Bopp photos more and more lately.
Stars and Observers are taking seriously the Light Painting!

At the beginning of July, we had our annual national amateur astronomers observation in Mt Grammos which is located in the Northern Greece, about 50km from Kastoria city. This imaging sequence shows how the stars and busy observers, all under a trully dark sky, are painting with light into the camera’s imaging sensor! There is even a green laser pointer which was used as a marker to the night sky for new sky watchers.
The image is a composition of 304 30sec exposures taken with a Canon 5D and a Sigma 15mm lens at f3.5.
