I collected exactly an hour's worth of data (20 x 3-minutes) through each LRGB filter (not nearly enough!) and stacked each set together in DeepSkyStacker using dark calibration frames).
The color channels were aligned and processed entirely in Adobe Photoshop to complete the image. Thanks for looking, and clear skies!
A deep image of M 51, the Whirlpool Galaxy, peeping through the integrated flux nebula. I've not noticed this in other images of M 51 before but perhaps I didn't look hard enough? Wise Band 3 IR data of the area shows some of the same structures so it does appear to be real.

Palouse Falls Galaxy
In 2013, I put a lot of time and energy focusing on capturing the night skies. Especially the beautiful milky way where it is almost impossible to capture it in the city. That's simply because there are too much light pollution release to the atmosphere from the amount of lights using within the city.
And I try to find and drive to locations that are extremely dark, as far as possible from the cities. Trying to get more connected to the universe. And of course capturing the night sky. After a few trip in the west coast. I found myself falling in love with this experience. And I hope to go to new places to capture the night sky from different parts of the world.
And this place - Palouse Falls State Park, is one of my fav trip from 2013.
I wish you all have a wonderful holiday and hope you enjoy this night sky as much as I do when I was there!
Happy New Year!!
This galaxy resembles a bull's eye, which is appropriate because its appearance is partly due to a smaller galaxy that passed through the middle of this object. The violent collision produced shock waves that swept through the galaxy and triggered large amounts of star formation. X-rays from Chandra (purple) show disturbed hot gas initially hosted by the Cartwheel galaxy being dragged over more than 150,000 light years by the collision. Optical data from Hubble (red, green, and blue) show where this collision may have triggered the star formation.

Excerpt from Wikipedia:
Galaxy Macau (Chinese: 澳門銀河綜合渡假城) is a casino resort located on the Cotai Strip, Macau, China. Construction on the Cotai project began in 2002. Its opening was rescheduled several times. Its developer, Galaxy Entertainment Group, announced on 10 March 2011 that the HKD 14.9 billion (US$1.9 billion) resort would officially open on 15 May 2011. The resort is designed by Gary Goddard. The resort currently consists of five different hotels, each with its own 'theme', Galaxy Macau, Banyan Tree, Hotel Okura, The Ritz-Carlton and JW Marriott.
When the Cotai project's first phase opened in 2011, the 550,000 square metres (5,900,000 sq ft) property offered around 2,200 hotel rooms comprising the Galaxy Macau hotel tower complete with casino and entertainment areas, as well as two hotel partners, the Japanese-owned Hotel Okura and the Singapore-operated Banyan Tree Hotel.
On 26 April 2012, Galaxy Macau announced that JW Marriott and Ritz-Carlton hotels would be added to the Cotai resort. Galaxy's Chief Financial Officer Robert Drake said it would start construction of the two hotels at the end of 2013 and begin operations gradually from 2016 through 2018.
According to a presentation released by Galaxy Entertainment, the total investment for Galaxy Phase 2 was estimated to be 16 billion HKD with construction completion scheduled for mid-2015. Phase 2 would consist of 450,000 square metres (4,800,000 sq ft) of new resort space, additional rooms across the five hotels and an increased casino table count of up to 500. Phase 2 was eventually opened on 27 May 2015.
Taxing out for departure from Prestwick airport near Glasgow in Ayrshire Scotland is this Travis Air Air Force Base Lockheed C5 Super Galaxy.
The Lockheed C-5 Galaxy is a large military transport aircraft originally designed and built by Lockheed, and now maintained and upgraded by its successor, Lockheed Martin. It provides the United States Air Force (USAF) with a heavy intercontinental-range strategic airlift capability, one that can carry outsized and oversized loads, including all air-certifiable cargo.
I made good use of the clear and dark Karoo desert skies on an early astrophotography trip with Tanja in April, 2014, to make this 5x3m image of the core of our Milky Way galaxy, which stretches beautifully directly overhead in the southern hemisphere.

A wet spinning tennis ball turned out like an astronomical object.
Shooting that type of shot in daylight is kinda cliché so I chose to do it at night using external flash.
I used both the built-in flash of the camera and the external flash (in slave mode).
Took me almost 50 attempts to do that and me and my friend got drenched by the end of the shooting.
But still it was totally worth it seeing that unique photograph.

Deuxième tentative de photographie de la Galaxie d'Andromède, notre voisine la plus proche. Sous un ciel bien sombre elle est visible à l'oeil nu. On aperçoit aussi ses deux galaxies satellite: M32 et M110.
Y a du progrès depuis ma première tentative mais j'essaierai de faire encore mieux à l'avenir :)
This photo of the Triangulum Galaxy was taken at the Northern Skies Observatory in Peacham, Vermont. The telescope is a PlaneWave f/6.8 17-inch CDK. The camera mounted on the telescope is an Apogee Alta F16M Monochrome CCD with a Kodak 52 mm full frame sensor.
Also known as Messier 33 (M33) or NGC 598, Triangulum is a spiral galaxy about 3 million light years away, has a diameter about half that of our Milky Way, and contains 40 billion stars. It lies within the constellation Triangulum in the northern sky, relatively close to the Andromeda galaxy.
Most observatory cameras are set up to take monochrome images only. A red filter, green filter, and blue filter are usually used to bring color to the final image. In addition to those 3 filters, an H-alpha filter was used for this photo. The H-alpha filter isolates a visible spectrum of light that shows destabilized hydrogen. The irregular shaped red objects in the photograph, some with white in them, are ionized hydrogen gas clouds. We are able to see them clearly in the photo because of the use of the H-alpha filter. These ionized hydrogen gas clouds, also called H II regions, reach temperatures of 10,000 degrees Kelvin and are massive areas of star birth.
Taking the Photo:
Taking the photo itself is pretty easy because everything is computerized. It is not necessary to look through the telescope, find the object in the sky and focus on it, or even be at the observatory to request a photo. The observatory is one of about 20 in the Skynet Robotic Telescope Network. To take the photo, we logged into that site and put in a "plan". For the plan, we specified the object to be photographed (M33), the filters to be used (the 4 filters mentioned above), and the exposure time (we used 5 minutes per image). A monochrome image is created for each filter used.
The plans are placed in a queue. The images are taken automatically when conditions are right, e.g. clear skies, dark skies, and the object to be photographed is visible to the telescope. That could potentially be a week or more, especially if there are lots of plans queued up or lots of cloudy nights. When the time comes, the door on the dome opens (if not already open), and both the telescope and door robotically position themselves to take the images. They also must continue to track the object precisely for the duration, in this case about 20 minutes (5-minute exposures for each filter, plus time to load the filters). Each of the 4 filters get loaded automatically at the point it is needed.
Processing the Photo:
The images created are in FITS format (Flexible Image Transport System), most commonly used in scientific applications, especially astronomy and microscopy. This format is not supported by typical photo editing software such as Photoshop or Lightroom. In order to process the monochrome images, I had to learn ImageJ, a free open-source, Java-based application developed by the National Institute of Health.
When I first opened the monochrome images in ImageJ, they were almost entirely black, with just a few white dots scattered around. Looking at the histogram, it very closely hugs the left boundary. There is data there, but it is all very dark. One of the first steps needed is to do a "logarithmic stretch" on each image. This effectively spreads out the histogram towards the center. Actually, this stretching also happens behind the scenes with traditional DSLR and other cameras. If shooting in JPG format, the camera's firmware does this stretching for you. If shooting in RAW, the stretching occurs at the point the RAW data is opened in image processing software such as Lightroom.
After the stretching in ImageJ, you basically do brightness adjustments on each of the images, then create a color composite from which you can do final color balancing. I also did manual image alignment. The stars in the composite should be white, so for example, if you zoom in on the stars and see red at the top of most of them, then the image associated with the red filter needs to be moved down one or more pixels in the composite. It was actually quite simple to do the alignment.
Additional options in ImageJ allow for noise reduction, sharpening, etc. There are also many available plugins, an example of which would be for building mosaics (analogous to panoramas). If you wanted to photograph the Andromeda galaxy on this telescope, for example, a mosaic would be required because the image of Andromeda is too large to fit on a single frame!
When processing in ImageJ is complete, the composited image can be saved in a variety of formats. I saved to TIFF, brought it into my usual software to set EXIF info, and did the noise reduction, sharpening, and other processing there as well.

Not my best astro image, probably my worst, the stars have no color, the galaxy has no detail and looks washed out and the image is noisy. I will have another go at processing this, damn think I may have deleted the subs already.

The Pinwheel Galaxy (M101) is a face-on spiral galaxy 25 million light-years away from Earth in the constellation Ursa Major. The giant spiral disk of stars, dust and gas is 170,000 light-years across — nearly twice the diameter of our galaxy, the Milky Way. M101 is estimated to contain at least one trillion stars. The galaxy’s spiral arms are sprinkled with large regions of star-forming nebulas. These nebulas are areas of intense star formation within giant molecular hydrogen clouds. Brilliant, young clusters of hot, blue, newborn stars trace out the spiral arms.
This NASA/ESA Hubble Space Telescope observation has captured the galaxy CGCG 396-2, an unusual multi-armed galaxy merger which lies around 520 million light-years from Earth in the constellation Orion.
This observation is a gem from the Galaxy Zoo project, a citizen science project in which hundreds of thousands of volunteers classified galaxies to help scientists solve a problem of astronomical proportions — how to sort through the vast amounts of data generated by robotic telescopes. Following a public vote, a selection of the most astronomically intriguing objects from the Galaxy Zoo were selected for follow-up observations with Hubble. CGCG 396-2 is one such object, and was captured in this image by Hubble’s Advanced Camera for Surveys.
The Galaxy Zoo project originated when an astronomer was set an impossibly mind-numbing task; classifying more than 900 000 galaxies by eye. By making a web interface and inviting citizen scientists to contribute to the challenge, the Galaxy Zoo team was able to crowdsource the analysis, and within six months a legion of 100 000 volunteer citizen astronomers had contributed more than 40 million galaxy classifications.
Since its initial success, the Galaxy Zoo project and its successor projects have contributed to more than 100 peer-reviewed scientific articles and led to a rich variety of intriguing astronomical discoveries above and beyond their initial goals. The success of the project also inspired more than 100 citizen science projects on the Zooniverse portal, ranging from analysing data from the ESA Rosetta spacecraft's visit to Comet 67P/Churyumov–Gerasimenko to counting killer whales around remote Alaskan islands!

The Triangulum Galaxy is a spiral galaxy 2.73 million light-years from Earth in the constellation Triangulum. It is catalogued as Messier 33 or NGC 598. The Triangulum Galaxy is the third-largest member of the Local Group of galaxies, behind the Andromeda Galaxy and the Milky Way. It is one of the most distant permanent objects that can be viewed with the naked eye. The galaxy gets its name from the constellation Triangulum, where it can be spotted. It is sometimes informally referred to as the "Pinwheel Galaxy."
finally our nearest galaxy neighbour 2.5 million light years away, the last object of 6 nights in a row with clear skies, no wind, no moon - and no problems :) there is another one waiting, but it is pretty faint so i need to add more data to the current 6h i got so far :) stay tuned :)

This huge galaxy is the nearest galaxy to us and it equals six full moons across the sky. It’s double the size of our Milky way galaxy and located 2.5 million light years from Earth. This galaxy is the farthest object that could be seen by the naked eye from a dark sky. It’s moving toward our galaxy in a speed of 110km/sec. It will collide Milky way in 3.75 billion years. Total exposure is 3 hours. Light subs 60 x 180 sec, Darks 20, Flat 20, Bias 50. Gear setup: Celestron RASA 8 @ f/2.0, iOptron GEM 45 guided by ZWO Mini guide scope and ZWO 120MM-S, Optolong L-Pro filter, ZWO 2600MC @ 0, Celestron Motor Focuser. Stacked in APP and processed in PI & PS.
Captured by the NASA/ESA Hubble Space Telescope, this image shows NGC 7513, a barred spiral galaxy. Located approximately 60 million light-years away, NGC 7513 lies within the Sculptor constellation in the southern hemisphere.
This galaxy is moving at the astounding speed of 1564 kilometres per second, and it is heading away from us. For context, the Earth orbits the Sun at about 30 kilometres per second. Though NGC 7513’s apparent movement away from the Milky Way might seem strange, it is not that unusual.
While some galaxies, like the Milky Way and the Andromeda galaxy, are caught in each other’s gravitational pull and will eventually merge together, the vast majority of galaxies in our Universe appear to be moving away from each other. This phenomenon is due to the expansion of the Universe, and it is the space between galaxies that is stretching, rather than the galaxies themselves moving.

Galaxies are gigantic far away systems of billions of stars each, held together by gravity. The Milky Way is our home galaxy in which our single star and solar system lives.
These are the Leo Trio found in the constellation Leo the Lion. But it is no coincidence that they look like they are together. They actually are quite close to each other and are interacting with each other. The top one, NGC 3628 known as the Hamburger Galaxy and the lower left, M66 came close to each other a long time ago. The disruption caused by gravity can be seen with a tidal stream coming off the Hamburger galaxy and the distorted spiral arms in M66 with intense star birth at its centre. The lower right galaxy, M65 seems calm, but it too will eventually experience crazy distortions as it is getting very close to M66. I imaged the Leo Trio over 13 moonless nights this past winter. I gathered 40 hours of total data using LRGB and hydrogen-alpha filters.
Equipment:
Telescope: Ceravolo300mm at f/4.9 (1470mm focal length)

NGC 3628, The Hamburger Galaxy or Sarah's Galaxy, is an unbarred spiral galaxy which lies about 35 million light-years distant in the constellation of Leo. Along with M65 and M66, NGC 3628 forms the Leo Triplet, a well known grouping of galaxies.

The Milky Way galaxy over some pine trees in Mount Laguna, California on Saturday June 22, 2019
This image is a noise-reduction stack of 5 frames each shot at 15 sec f/2.8 ISO 4000 with a Canon 6D and a Sigma 15mm EX DG lens. This is my first time experimented with aligning and masking multiple frames to reduce noise reduction. Due to the complex foreground - the intricate - details of the pine tree branches - lining up and masking the layers was a lot more challenging. This image isn't as sharp as I had hoped for, but I hope to improve upon this technique over time.
Weather conditions were perfect - no wind, clear skies, and pleasant temperatures.
Mount Laguna is a small census-designated place (CDP) in San Diego County, California. It is approximately 6000 ft above sea level in a forest of Jeffrey pine, east of San Diego in the Laguna Mountains on the eastern edge of the Cleveland National Forest (named after former president Grover Cleveland). The hamlet sits at the high point of a scenic drive on Sunrise Highway from Interstate 8 to Highway 79. Mount Laguna consists of a small general store, rustic lodge and cabins, local restaurant, rural post office, and campgrounds adjacent to the Pacific Crest Trail. The Laguna Mountain Recreation Area surrounds the village, and the visitor's center for the pine-covered area is located here. The mountain backcountry of San Diego County is high enough to receive snowfall in winter months, and the Mount Laguna region offers locally-unique winter recreation in the form of snow play, sledding, and cross country skiing for several days after larger storms.
