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.

- www.kevin-palmer.com - I finally got around to processing the images of the Andromeda Galaxy from August. I inserted a picture of the moon taken with the same lens for a size comparison. In dark skies (like where this was taken) you can easily see the bright core of the galaxy with the naked eye. The crazy part is the galaxy is at least twice the size shown in this picture. I just don't have the equipment to capture the faint outer portion. There are two more galaxies in this shot if you know where to look. This is a stack of about 100 pictures taken with a Takumar 135mm f2.5 lens. All shot at 4 seconds, f2.5, iso 12800.
Pushing my astro gear to the limit: Messier 51 (a.k.a. Whirlpool Galaxy) is a 100 billion stars galaxy 23.16 million light years away from Earth (with a tiny size of only 11 x 7 arcmin)...
The Orion Nebula (also known as Messier 42, M42, or NGC 1976) is a diffuse nebula situated south of Orion's Belt. It is one of the brightest nebulae, and is visible to the naked eye in the night sky. M42 is the closest region of massive star formation to Earth. The M42 nebula is estimated to be 24 light years across.
