Very probably, this is the first amateur image taken over this Supernova Remnant. . 33.5 hours was invested to take off from the noise background these faint filaments.. http://afesan.es/Examples/SNR%203C400.2 ... gitta).jpg

As M31 recently was an apod this image probably doesn't stand a chance. The recent apod was taken using a Vixen APO with DSLR. This image was made using also a small refractor (9.2 cm) using a cooled CCD.
Details:
Telescope: TMB-92
Camera: QSI-583ws
Mount: NEQ-6 with OAG
Exposures:
19x300s L
3x300s B
9x300s R,G
9x900s Ha
Total: 5,6 hours
Hi
There was recently a picture of OU4 - The Giant Squid Nebula taken with the Isaac Newton 2.5 metre telescope on APOD. This image was taken with a Televue NP127/FLI astrograph from my back garden over 5 nights and consists of 28x10 minutes Ha, 45x10 minutes OIII and 23x10 minutes SII. The blue of the 'Squid' shows up really well against the greenish yellow of Sh2-129.
IC 410 an emission nebula about 12,000 light-years from Earth in the constellation Auriga. Near the center of the nebulous region is a star cluster ( NGC 1893) and just to the bottom right of this cluster lies two structures that resemble tadpoles. These structures are made of leftover hydrogen and dust from the formation of the star cluster and the "tails" are from the solar wind coming from the stars of NGC 1893.
This was imaged from my backyard in Ocala, Florida. I used 20 minute exposures totaling 4 hours to capture the detail in this nebula and color was added by imaging through red, green and blue filters and processing in Photoshop CS5.
Imaging telescope: Astro-Tech 8" Ritchey-Chrétien (focal length 1625mm)
Imaging camera: QSI 683 wsg-8 cooled CCD camera

They call it the Supermoon, although it's not much bigger than a regular full moon, but I won't argue with that. It was a challenge to find a location to shoot this evening's moonrise. Cloud threatened the party in Wellington New Zealand, so I drove for a few hours to a location I have spent many nights photographing the stars.
It was tricky to get a perfect lineup tonight and it didn't work out exactly as planned, but I'm still happy with the result! And check out the people next to the lighthouse as a good scale reference!
This is a singe exposure shot taken 3.7km away from the lighthouse.

Some of my recent images.
All are combinations of C11 at f/6.7 and hyperstar data.
All taken in the Netherlands.

(Airglow (also called nightglow) is the very weak emission of light by a planetary atmosphere. In the case of Earth's atmosphere, this optical phenomenon causes the night sky never to be completely dark, even after the effects of starlight and diffused sunlight from the far side are removed.)
Just after midnight on August 12 2013, I captured more than 30 meteors, including a brilliant fireball, in about one and a half hours. They are all Perseid meteors, and each of them seems to be shooting toward one single point below the horizon.
This anti-radiant effect is a consequence of using a wide angle lens, and where it was aimed. At this time, the radiant was above, so visually these meteors would generally be seen as diverging. However, since the radiant is behind the camera, we get the impression of convergence.
All meteor showers appear to diverge from their radiant, and converge on their anti-radiant, on the opposite side of the celestial sphere. Since the radiant is normally above the horizon, the anti-radiant is below it, and we seldom get a visual impression of convergence. This image shows that effect very nicely.
Photo details: Camera Model: Canon EOS 5D Mark II; Focal Length: 24mm; Aperture: f/1.4; Exposure Time: 15 s for each shot; ISO: 4000. 23 photos are stacked to show all meteors in one picture.
Also, i made a short timelapse video:

Very recently Robert Gendler released a new image of M57 (http://www.robgendlerastropics.com/M57-HST-LBT.html) which is very nice. I wanted to make a notification that I had an image quite similar to this one already processed and published in May 2013 on my site and on Flickr. It is a combination of the core taken by the Hubble space telescope together with the Subaru and LBTO data.
