Cosmic Cocoon

Explanation: The Cocoon Nebula (IC 5146) is an emission/reflection nebula located in Cygnus. It's located at about 4.000 light years and it's totally surrounded by gas and dust clouds. Because of that, the name of the nebula: Cocoon. It reminds to a little cocoon with a beatiful pink flower inside. The dust clouds are really big, and also all the complex is surrounded by faint clouds of H Alpha. This is the real difficulty of this nebula. With a wide field telescope we will could capture in RGB all the information of the dust clouds and the brightest part of the nebula. And in an adicional night we can use a narrowband filter to capture the H Alpha emission around the dust clouds. Then we can compose with both images a colorful astrophoto of this beautiful part of the Cygnus constellation.

Gear: SVBony SV550 80ED triplet + ZWO Asi 294MC Pro + Sky Watcher HEQ5 Pro + SVBony UV-IR blocking filter (7 hours integration) + SVBony SV220 duo band filter (7 hours integration). Totally automated by ZWO Asi Air Plus and prcessed with Pixinsight and Photoshop.

Galaxy NGC7331, on Pegasus, with other galaxies of an apparent size much smaller and much more distant.

The main galaxy (NGC7331) is almost 40 million light-years away. The smallest galaxies in the background are at a distance of between 290 million and 400 million light years. And galaxies that are so small they look like stars must still be much further away. Image of 6.3 hours of integration with photos of 150 seconds of exposure each one.

I love your picture! But please, can you post a larger version of it that I can see? I don't have instagram, so I can't see instagram pictures, and your other portfolio is so large (and in Spanish) that I couldn't find anything at all there.

One of the most spectacular areas in the night sky is pictured in this image. The combination of yellow-reddish (caused by the red super giant Antares) and blue reflection nebulae are quite unique. Additional SH2-9, an emission nebula, and globular cluster M4 are captured in the picture.
Eight single panels were combined into a mosaic to cover the most colorful area of this region.

Thank you! I asked for a way for me (who has not got Instagram) to see a larger version of your picture. And now you have made a larger version perfectly accessible to us!

Thank you! It's a great image! I love all the beige dust surrounding the well-known pink hydrogen alpha nebula in the center!

The Ancient Galaxy and the Young Stone


On August 12 and 13, 2023, I photographed the Perseid meteor shower for two consecutive nights in front of the iconic giant boulders at Alshan Baolage area of Sunite Geopark, located deep in Inner Mongolia, China. ("Sunite" is the name of a Mongolian tribe from the Ming and Qing dynasties; "Alshan Baolage" in Mongolian means "Sacred Spring," with "Baolage" translating to "spring water.")

The foreground of the photo, a giant weathered granite, said to be formed in the Cretaceous Period (spanned approximately 145.5 to 65.5 million years ago), still looks young compared to the ancient Milky Way.

The Milky Way background was taken at 1:06 a.m. on August 13th. At this time, the Perseids were located right in the center of the Milky Way, and the tilt of the Milky Way perfectly matched the angle of the foreground granite. Soon after, the moon was set to rise, so a white glow had begun to emerge on the horizon, highlighting the distinct contours of the granite. This location experiences minimal light pollution, so the green and pale yellow airglow in the night sky added a romantic hue to the photo.

Finally an opportunity to capture the Chinese space station, Tiangong, transiting the Sun. Unfortunately, cirrus clouds overhead impacted the contrast and dynamic range and a better result will follow in due course. Further details at https://www.perseus.gr/Astro-Sat-Trans-2023-08-29.htm.

The Nothing Nebula!

Presenting a very rarely imaged target, Sh2-124 or the nothing nebula. Named as there is really nothing written about it.

This target is located in Cygnus at 8500 light years away from us. It bears resemblance to trifid nebula and the it's closest neighbor, the cocoon nebula. Much like the cocoon, this nebula has an intense starfield. An Ha frame revealed 9000 stars in the vicinity of this nebula.

One interesting object I saw while editing is the really tiny smudge that looked like a duck at the center of this image. When I loaded the coordinates to Simbad and Aladin, I could clearly see the target in the sky survey. It's a region around V645 Cygni. Never heard of it before. I researched more.

V645 Cygni is a star-like condensation in a nebula. The nebula is associated with the rocket-infrared source CRL 2789. First publication that talked about this region was in 1977.

Link : https://ui.adsabs.harvard.edu/.../1988A ... ./abstract

I had an eye on this target since last year but since I had only a color camera, I wasn't able to extract much details even with longer exposures. This most definitely is a mono target.

The sharpless catalogue talks about not having an Oiii signal but believe me, that signal is there only a bit dim.

Mount: Skywatcher EQ6-R Pro

Super Blue Moon over Pyramids of Egypt

Super Blue Moon over Pyramids of Egypt by Ahmed Waddah, on Flickr

Image is a single shot of the Super Blue Moon on the early hours of the 31st of August around 5 am which was around the time given by timeanddate.com for the second full moon of August for my location in Giza, Egypt. 
Saturn can be observed as a tiny spot of light around the moon.

Blue Supermoon Rising in Chicago

I captured the second full moon of August right as it aligned with the antennas atop the John Hancock Center, the fifth tallest building in Chicago, shown in this HDR composite.

Date: August 30, 2023

I was at the Berkeley Waterfront to catch the 99.4% full moon setting behind the North Tower of the Golden Gate Bridge at 5:50 a.m. 30 Aug 2023. The fog was moving in fast as the moon set, and I feel very lucky to have caught it (I have tried a few times in the past and was always thwarted by fog or the marine layer). I was 9 miles away from the bridge giving a relative Moon size of 470 feet.

Canon EOS Ra, Askar 72mm f/5.6 with 2x Teleview Powermate (800mm focal length), f/12 8s IS0 1600. This is the longest shutter speed and highest ISO I have ever had to use on a full moon due to the fog.

A blue moon is the second full moon in one month- A blue moon occurs once every 2-3 years on average.

ISS Transits the Moon
http://www.perseus.gr

I had indications during the past week of a possible ISS transit against the Moon and which included very minor orbital maneuvers, thus making matters interesting. All is well that ends well as I got my lunar transit and in spite of clouds coming and going all day and with some turbulence in the atmosphere after the Sun had set.

Please note that the middle instance of the ISS in the attachment involves the ISS precisely over the Apennine Mountain range and the landing area of the Apollo 15 mission.
