The Ring Nebula (M57) from the backyard
Canon 5D through a Celestron C8-SGT
I reprocessed the M57 images in DeepSkyStacker (rather than Nebulosity) with improved results. Also spent a bit more time playing with curves in Photoshop.
I decided not to crop the image, so check out the larger sizes for a better view of the actual nebula.
Stack of 31 x 8 sec. exposures of Orion area beginning at 05:47 EDT during morning twilight, Rochester, NY. The track of the International Space Station can also be seen. Processed with DeepSkyStacker.
This is my first attempt to get a decent result out of the free software #DeepSkyStacker with a stack of 5 raw images (with Canon 5D Mark IV with Walimex 14mm f2.8 at 30 seconds ISO 2500..) over #Scheyern monastery (#klosterScheyern). With the light polution heading south, I was hoping to get more Milky Way to be visible, but it only gets visible after monstrous post-processing in Photoshop and Lightroom.
Given the fact that the road was almost pitch dark, I think the result is not too bad after all. To get a darker sky I would need to drive quite a bit. The nice thing is that the obvious noise at ISO 2500 is almost gone with that many stacked shots. #MedianStack

histogram tweaks, curves
i had taken about 90 minutes worth of 60s exposures intending to make a movie. i'm still struggling with doing a histogram transformation on these 90 images in some automatic way. so i thought i'd stack some of them and see what i could get out of them in a still image.
This is a shot of the nebula around the star Sadr in Cygnus, sometimes known as the 'Butterfly Nebula'.
This shot was taken in November 2011 but I've been re-editing and tweaking it the last month or so.
This shot was taken from my imaging site in a lowly car park in Ispwich, Suffolk... full details are:

This is M20, the Trifid Nebula. It's interesting because the pink and blue colors are very distinct when imaging this target. This lies in the dense star fields of Sagittarius and lies close by to M8, the Lagoon Nebula, and at the top of the image, M21, which got cut off when I cropped it. This is a result of over 30 minutes of exposures.

Stacked from 2 frames at 4 seconds each taken with 50mm f/1.2 Ai-S Nikon manual focus lens. Taken wide open at f/1.2, results in weird shape on bright stars near the corners. Open star clusters M36, M37, and M38 are visible with locations noted in the standard view page. Surprised how much detail came out at 50mm, will have to check them out with the telescope soon.
My first somewhat successful deep sky image. This is M45 or "Pleiades" Star Cluster. I learned a lot from this experiment and hope to have better success in the future. I was only able to pull part of the dust cloud due to the extreme light pollution where I live. I will be investing in a good light pollution filter in the near future.

The Dumbbell Nebula (M27) from the backyard.
This was from my first night of (attempted) astrophotography, so it's not much to look at. It does show a bit more detail in the larger size, though.
Canon 5D through Celestron C8-SGT.
4 x 30min exposures stacked with DeepSkyStacker.
Canon 5D3 with CGEM 1100HD. ISO 1600 with stack of 5 shots at 10 minutes exposure and one shot at 3 minutes blended in the center for washout. Seeing was excellent. Prime focus, manually guided with a dark frame for each shot. Celestron Off-Axis Guider was used with Orion's 12.5mm illuminated reticle eye piece. Processed using Deepskystacker.
Probably the best of the globulars. Here the excellent seeing allows nearlly pin-point stars. Even with only five shots the noise is very good for ISO 1600. We see a lot of the dimmer stars at the edge of the cluster. I used to run 15 minutes at ISO 800 with the 550D so (with manual guiding) this is easier!

What does the Andromeda galaxy really look like? The featured image shows how our Milky Way Galaxy's closest major galactic neighbor really appears in a long exposure through Earth's busy skies and with a digital camera that introduces normal imperfections. The picture is a stack of 223 images, each a 300 second exposure, taken from a garden observatory in Portugal over the past year. Obvious image deficiencies include bright parallel airplane trails, long and continuous satellite trails, short cosmic ray streaks, and bad pixels. These imperfections were actually not removed with Photoshop specifically, but rather greatly reduced with a series of computer software packages that included Astro Pixel Processor, DeepSkyStacker, and PixInsight. All of this work was done not to deceive you with a digital fantasy that has little to do with the real likeness of the Andromeda galaxy (M31), but to minimize Earthly artifacts that have nothing to do with the distant galaxy and so better recreate what M31 really does look like. via NASA ift.tt/33xOKAd
