This is the a portion of the Milky Way, a section of our home galaxy, that can be seen at the zenith in mid-summer around midnight. The diffuse whiteness are millions of stars in one of the spiral arms of our galaxy. The dark areas are clouds of interstellar dust and gas along the plane of the galaxy between spiral arms. It obscures a multitude of stars behind it.
First attempt at stacking with DeepSky Stacker and 10 images of Andromeda. I used 10 lights @ 60 sec exposures, along with 5 darks @ 60 sec exposures all at ISO 400. Brought final stacked image into Lightroom and made some adjustments...used some radial filters to help the galaxies out a little. So much to learn.
Here's a partially successful attempt at stacking intended to reduce the visibility of the the light cloud that persisted all evening. There's still too much haze for my liking, however the final product is better than any of the individual 15 light frames. I limited the shutter speed to 10 seconds to reduce the visibility of the clouds, although in hindsight it may have been better to go longer so that the Milky Way became visible. Messier 4 is easily seen to the right of Antares at the lower left of the image. Only the brightest stars of Messier 80 are visible; M80 roughly forms an isosceles triangle with Antares and Saturn, the latter at the upper left of the image. A surprise guest is the open star cluster NGC 5897, a barely visible tiny fuzzy patch to the right of Mars on the right side of the image.
The exposures were taken with a Canon 70D using the long exposure noise reduction features, which negated the need to take separate dark frames. The stack, compiled using DeepSkyStacker, includes 10 flat frames and 10 bias frames. The camera was mounted on an iOptron SkyTracker and the camera was fitted with a Sigma 50mm ART lens. All exposures were shot at f/1.4, ISO 800 in RAW format. Taken in Lake St. Peter Provincial Park, Ontario, July 23rd 2016.

An unguided/untracked, short-exposure view of the Great Orion Nebula captured with a series of 1.3 second long exposures using a Nikon D5100 DSLR and a Nikkor 105mm AI-S telephoto lens.
This picture also recorded a series of tracks that may be from two geostationary satellites (these appear as blue, dotted lines to the left of the Orion Nebula, see the image notes for the precise location). The satellites appear as dotted lines because each one of the 33 images used to create this final stack of pictures was offset from one another to remove any movement in the stars caused by the earth's rotation. Thus, given this shift to align the star images any earth-stationary object will appear to move in steps between each exposure (thus the satellite images appear as dotted lines - one dot for each exposure).

The Heart (IC 1805) and Soul (IC 1848) Nebulae are emission nebulae i.e. clouds of ionized gas, that lie about 6500 light years away in the constellation Cassiopeia. Between them is the star cluster NGC 1027.
Not brilliant framing, but, as you know, it's difficult when you're pointing your camera at nothing - next time I'll try this at 175mm. Still, half a soul is better than being completely soulless. :) The Soul looks more like a pork chop to me, but I guess Pork Chop Nebula doesn't have the same ring ;)

First try with autoguiding using PHD2. Unfortunately the 3D printed guidescope mount was not nearly robust enough. 2/3 of the exposures were thrown out.

Aquisition time: 7.10.2013 between 01:00 and 02:00 MSK (UTC+4)
Equipment:
Canon EF-S 60mm f/2.8 macro USM lens and Baader Planetarium 2" UHC filter mounted in front of the lens via step-down ring attached to Canon EOS 60D running Magic Lantern 2.3 firmware override riding on Vixen Polarie tracking platform over photo-tripod (alltogether codenamed "Anywhere Is, SWANS configuration").
Aperture 21,4 mm
Focal length 60 mm
Tv = 30 seconds (I have aligned Polarie blindly - by latitude value and compass.)
Av = f/2.8
ISO 1600
Exposures: 12 (not enough) (plus 5 dark frames (badly not enough) and 5 offset frames plus 3 fake flat-field frames).
Processing: Images were converted to 16-bit TIFFs in Canon DPP and outputs were fed to DSS.
16-bit stacking result was processed in Photoshop.
Note: greed is bad. Instead of shooting Pleiades and rising Orion I should have concentrated on this target. And now I have three bad datasets instead of one mediocre :(

I finally managed to get some good data from my light polluted backyard. We have a long weekend starting tonight and clear skies every night. The moon rises late and it won't be too cold just after the end of twilight. So, here's a 30 minute (10 x 3 minute exposures + darks) stack of the Great Orion Nebula (M42), the Running Man Nebula, the Fire Nebula, and the Horsehead Nebula. This is a first go at the post-processing. I'm going to try a few other techniques later.

Thought I'd apply the new technique to this one, which is a bit tricky due to the number of stars (I haven't counted them, but there's a lot!). Good practice though - took several iterations before I came up with something that I think is an improvement on the last one. The fainter areas of the Heart are now just visible and the stars are more controlled.
Moon's back and I've run out of things to reprocess. Not sure what I'm going to do now :(
Did someone say work? ;)

The famous Double Cluster (a.k.a. h and Chi) in the constellation Perseus, with an alternative route of post-processing to digitally reduce chromatic aberation. Imaged with TAIR-3S @ f/5.6 on Samsung NX30 with Rollei Astroclear (anti-citylight) filter. 23 subs of 30 s exposure. ISO 3200.
Stacking with DeepSkyStacker. This time, I first used Adobe Photoshop to multiply the somewhat defocused Red channel with the sharp and crisp Green channel to remove some of the chromatic aberration. For the Blue channel, the defocus due to chromatic aberration was substantially less than for Red. Further post-processing was done with Aurora HDR 2018 (tonemapping, color corrections, HDR cosmetics) and ImageJ (2x2 binning). I would be glad to hear your opinion which version you like better!
The constellation Cygnus, the North America Nebula, the Milky Way, and the tops of my neighbor's ponderosa pine trees.
This is 2 images combined by DeepSkyStacker, and postprocessed in Gimp to accentuate the region around the NAN at the expense of the rest of the image. This is my first image with DSS, and I am very encouraged by the result. You can even faintly see the Pelican Nebula next to the NAN.
The stars were tracked with my hand-operated barn door tracker, and the exposure was somewhere between 15 seconds and 2 minutes. I was using a hand tape recorder to note the exposure data, but alas nothing is on the tape. I'm guessing 1 minute.

The ETA Carina Nebula is the brightest and biggest in the sky however it is less famous that the Orion Nebula as it is only visible from the Southern Hemisphere. The glowing pink is Hydrogen Alpha emissions from Ionized H2 gas. The massive star ETA Carina may die soon in a Hypernova that could be visible during the day.

Couldn't resist this. Only found out about this last night (tonight) and as it was clear I felt obliged!
For those that don't know - or don't care :) - a supernova is a star that has come to the end of its life and exploded
On the left is the image I took on 3 May, and to the right is the quick and dirty image I've just taken. The supernova is kind of obvious (more so with the yellow lines pointing to it!)
The "surrounding" stars are in our galaxy, probably just thousands of light years away. The supernova, equally as bright, is in M51, the Whirlpool Galaxy, and is about 31 million light years away. Which also means of course that it went supernova 31 million years ago. Fascinating stuff. :)

- www.kevin-palmer.com - On a rare winter night when it was both clear and above freezing, I headed out to Spring Lake for some astrophotography. I began to set up my iOptron Skytracker, when I realized I forgot my polar scope. That meant I could only do a rough polar alignment and was limited to about 1-minute subs. I was surprised how much detail was captured. This is a stack of 15 1-minute pictures, plus dark and bias frames taken with a 50mm lens. After stacking I processed it in Photoshop using the Astronomy Tools plugin to help bring out the nebulosity.
