I like this one the best. The Levels and Curves adjustment in PS hasn't blown out the cores in the Nebulas, and by un-checking the "Re-move Hot/Cold Pixels" under the Cosmetic tab in DeepSkyStacker has made the stars better.

The Orion Molecular Cloud Complex (also often referred to as simply the Orion Complex) refers to a large group of bright nebula, dark clouds, and young stars located in the constellation of Orion. The cloud itself is between 1,500 and 1,600 light-years away and is hundreds of light-years across. Several parts of the nebula can be observed through binoculars and small telescopes, with some parts (such as the Orion Nebula) being visible to the naked eye.
The Horsehead Nebula (also known as Barnard 33 in emission nebula IC 434) is a dark nebula in the constellation Orion. The nebula is located just to the south of the star Alnitak, which is farthest east on Orion's Belt, and is part of the much larger Orion Molecular Cloud Complex. The Horsehead Nebula is approximately 1500 light years from Earth. It is one of the most identifiable nebulae because of the shape of its swirling cloud of dark dust and gases, which is similar to that of a horse's head when viewed from Earth.

After I have spent hours to watch the starry sky, I tried to realize a image of our nearest neighbor galaxy : Andromeda M31.
Wihtout using a tracking mount, I took 64 images (+ 20 darks) that I superimposed with DeepSkyStacker software.
In order to improve the clarity of the photograph, I used lightroom. But the focus is not perfect unfortunately...

Stack of 23x 1 minute exposures of M51 to show the Supernova that recently erupted. (tagged, Approximate magnitude 14.5)
The supernova just looks like a small faint star, no brighter than most of the other faint stars in this image ... but keep in mind that it's in Galaxy M51, 31 Million light years away from us. The other faint stars are probably only thousands of light years away, and are within our own galaxy. The supernova could be 5000x further away!
Skywatcher Maksutov Newtonian telescope 190mm F5.3. LXD75 Mount. Canon T1i DSLR ISO800.
I took about 50 exposures mostly 1 minute each. Most of them are streaked too much to use even with my low standards, but I'm happy I was able to get some ok 1 minute shots, usually i can only do 30 seconds. I was setup on a cement patio tonight instead of in the grass which may have helped.
I stacked this using DeepSky Stacker, with a set of dark, bias, and flat field frames. I had stacked it in Pixinsight 1.7 but had some difficulties. after stacking I did some processing in Pixinsight and Gimp to make the galaxy and it's neighbours more visible.
Attempt to capture the Milky Way in the Summer Triangle with my shiny new DSLR. Stack of 9 twenty-second exposures with the kit lens at f/3.5, 18mm, ISO 1600.
I took this near Utah Lake (same place as my Andromeda photo). It was pretty hazy and I had difficulty separating the Milky Way from the sky glow.

I said my previous reprocess of this was my last - I lied! Having been inspired by Danny Lee (Danny_astro), I followed Anna Morris's excellent video tutorial on separating stars from DSO and processing them in separate layers. This is an excellent image on which to practice and, after several attempts, it seems to have yielded an improvement. The original star colour is retained, the stars are altogether better and the DSO is less forced, compared to my last process. I may be using this technique more frequently in future, as I need all the help I can get! :)

Inspirado pelo @galactic.hunter , eu resolvi tentar o meu mais longo projeto, diretamente de onde moro (bortle 8), em uma galáxia relativamente pouco brilhante, a M90 (NGC 4569 de 9.5 a 10.2 Mag). É possível ver muitas galáxias no lado esquerdo da galáxia ao centro. Foi um projeto que durou quase dois meses, entre vários dias de mau tempo ou de lua, os quais não fotografei. Remover os gradientes de poluição luminosa é bem difícil e acaba trazendo ruído pra foto. Embora tenha dado bastante trabalho, fiquei bem feliz com o resultado e irei com certeza ter mais projetos semelhantes, porque galáxias são simplesmente fantásticas!
Inspired by @Galactic.hunter , I did give it a try on my biggest project so far, directly from my house (bortle 8 city), in a galaxy not very bright, the M90 (NGC 4569 in sth between 9.5 and 10.2 Mag). We can see many more galaxies on the left of the main galaxy in the picture. It was a project that took almost two months and many days of bad weather or moonlight, which I couldn't do any pictures. Remove the gradients that I get from the city light polution it's really hard and brings the noise way up. It was not easy, but I'm really glad with the result and I'm definitey doing more projects like this in the future, because galaxies are mind blowing!

Comet c/2012 S1 ISON imaged from my front yard this morning! Note the faint cyan coloring of the comet.
Two "bonus" satellites crossed the field, one smack-dab through ISON's tail and a dim one in the lower left. Just above the middle of the dim one's track is a faint galaxy, NGC 3433. The brightest star is 53 Leonis.
The sky was brightening quickly as I was getting these images, hence the bluish cast in the lower part of the frame.

This was my first ever try at a proper RGB image. I used a set of Astronomik filters and took 10 x 5 minute images for each red, green and blue filter and then combined them to make this color image. I still need to take some luminance channel images and maybe some hydrogen-alpha and OIII images to combine with the color data to bring out more structure and fine detail.

The rock arch near White Tank campground in Joshua Tree. I shot a similar photo of the arch with my Rebel XT last year, but the noise and colors ended up out-of-control. Right after the sun set around 5 PM, the entire sky clouded up. We huddled around a small fire in freezing temperatures for several hours, constantly hoping that the sky would clear so we could shoot star photos. We finally decided to take turns checking the sky at intervals, and around 10:30 PM I went to bed. After half an hour, just when I had gotten warm and was drifting off to sleep, Matthew Saville informed me the sky had cleared. Michael Relich, Matthew, and I proceeded to shoot star photos and timelapse until around 6 AM, when we finally went to bed to catch a couple hours of sleep. After shooting this image, I set up my dolly and filmed timelapse of the arch.
Image Creation:
I shot 8 15-second exposures at ISO 6400 and f/2.8. These photos provided the data for the stars, and the exposure time was short enough for no star trails to appear. I also shot 4 30-second exposures at ISO 3200 and f/2.8. During these 30-second photos, I put a CTO (orange) colored gel over my headlamp and light painted the arch so it wouldn't be a silhouette. All images were shot on my tripod-mounted 7D with a Tokina 11-16mm f/2.8 at 15mm. The camera was not moved between images.
Processing:
I used DeepSkyStacker to align the 8 star images. Basically, this shifts the images so that the stars are always in the same place, in order to correct for the rotation of the Earth. I layered the aligned images in Photoshop using lighten mode, which reduces noise and brightens the image a bit. I also stacked the light-painted arch photos using lighten blend mode, which again reduces noise and evens out the light painting. I then flattened the stack of light-painted arch images and the stack of aligned star images. I blended together these two using quick masks. Finally, I massively brightened the image and enhanced contrast using Curves, increased the saturation, and sharpened with Unsharp Mask.

This is an image of Messier object 1, the Crab Nebula. Taken as a part of a test done in the back yard to check the way the PEC was working on the mount. I was also testing to see how well double stacking the Baader UV/IR filter with the Moon and Skyglow filter would work to give tighter stars.
I was pleased with the results of the double stack when using it on the SV4 refractor. On the Mak, it gave better results than expected. I was able to get better looking diffraction spikes for focus so it helped ensure good stars.
The stack is the result of 10 subs of 10 minutes each at 400 ISO using the full spectrum modified Pentax K10D camera on the 127mm Orion Maksutov Cassegrain operating at F13.1.
Only after taking these pictures and then looking at them a day or so later did I realize that there was something moving in the frames. It required a bit of work, but I believe that the object is identified in this list from the Minor Planet Checker:
Object (33078) 1997 WN35 RA 05 34 23.2 DEC +22 20 36 Magnitude 19.9 Motion in Arcsecs/Hr: RA 76+ DEC 0-
The finding of this object in the data meant that I had to get something out of the stack, which meant that I would work it over via trial and error.
Data was calibrated in Maxim using 77 darks, 15 flats, 256 bias. I had some flawed darks so I spent a long time chasing the errors. Stacking was done in DSS. Processing in PixInsight for DBE, background calibration, masked stretch, A Trous wavelets for de noise and sharpening, and a few more curve/histogram stretches before annotation. TIF files exported and then passed through LR3 for publish.

This is just a bit of fun really - my kit doesn't take images like this :)
Did my third recent session on the horsehead last night, and chalked up another failure! So, to get rid of the blasted Alnitak, I cropped the image by a ridiculous amount and played with it. This is just short of 3 hours of 60 second subs. Spikes were added to cover the horrendous ones that were already there :)
Gave me something to do with the data! :)

This is another attempt at getting an image of M81 & M82. It came out markedly better than last time, due to now having a (somewhat basic) tracking mount to use. I had some issues getting the equatorial wedge to work well, so this is just alt/az (baby steps), which limited my exposure to about 30 s before getting frame rotation. Still, it worked much better than when I was limited to 1.6 seconds on a fixed mount! It was also shot at 340 mm as opposed to 200 mm, with no drizzle applied. Additionally this one was shot in Texas with darker, calmer skies, although some of the stars still came out a little distorted. However there was an issue with my interval timer settings that caused half as many exposures (and dark frames) as I was planning, 12 minutes of total integration instead of 25. Annoying to wait around half an hour only to get 12 minutes of data. Ah well there's always next time.

The Milky Way is continually generating radiation in all directions, in the form of light; X-rays; infrared, ultraviolet; gamma rays & radio. When radiation at the wavelengths of visible light collides with the sensor in a digital camera, you get photos like this one, taken at the Telstra telecommunications station at Maddens Plains in New South Wales, Australia. The microwave dishes mounted on the tower are sending and receiving radio signals that carry voice and data communications traffic along the east coast of Australia. I thought it fitting to have these earthly and heavenly radiation generators in the same shot. Something I remember distinctly about capturing this image was that I had to lay on my back underneath the camera and tripod so that I could line up the shot and make sure the focus was sharp. I think it was worth the discomfort.
This photo was created from two nearly-identical images that were combined to reduce the amount of digital noise present in them, using a process known as “stacking”. Each photo was taken with equipment and settings as follows: Canon EOS 6D camera, a Canon 40mm STM lens @ f/3.2, an exposure time of 6 seconds @ ISO 6400.

I finally got to see and image Comet ISON (C/2012 S1). Used DeepSkyStacker to stack only on the stars showing the comet's movement and color better. The Zodiacal light was pretty bright right where the comet was, also the comet was moving very quickly so exposures longer than 2 minutes resulted in a oval shaped coma. Using a NEX-5 mounted to a C8 OTA, f/6.3 reducer, CG-5GT mount. Guided with a Orion SSAG and 50mm guidescope piggybacked on the C8.
Comprising NGC 869 (lower left) and NGC 884 (upper right). Photographed in poor conditions: although I took around 30 frames, I deleted all but 5 that were less affected by wind and passing cloud. There's still some mistyness here around the brighter stars due to thin cloud.
Just 5 x 2.5-minute exposures at ISO 1600, f/6.25. Modified EOS 600D & Sky-Watcher ED80 refractor, piggybacked on a Celestron C8 telescope for manual guiding.
Registered and stacked using DeepSkyStacker; initial curves adjusted in Canon Photo Professional; final curves and colour balance adjusted using Paint Shop Pro; noise reduction via CyberLink PhotoDirector.

Mein erster Versuch mit der Astrotrac TT320X-AG Nachführung.
Die Astrotrac wurde auf ein Manfrotto 055XPROB Pro Stativ montiert.
Die Ausrichtung erfolgte mit dem Manfrotto Getriebekopf 405 und die Kamera ist auf einen Manfrotto Kugelkopf 498RC4 montiert.
Das Fotos besteht aus 8 RAW Einzebildern (plus zusätzlich 3 Dunkelbilder) und es wurde mit DeepSkyStacker zusammen gestackt.
Daten zu den Einzelbildern:
Belichtungszeit: 50sec.
Blende: f4,5
ISO: 2500
Brennweite: 70mm
Für die Aufnahme habe ich meine Canon EOS 7D und das Canon 70-200mm f2.8 IS II USM Objektiv verwendet.
Zusätzlich wurde noch ein Astronomik CLS Clip Filter eingesetzt um die Farben etwas besser heraus zu holen. Zusätzlich wurde das Foto mit DPP etwas nachgearbeitet.
