Unfortunately my focus was of a bit.
Nothing fancy here, just a simple stack of three unguided images without calibration frames. There was a lot of cloud at Lake St. Peter that evening, so I didn't bother setting up my SkyTracker and just took a few wide angled shots with my camera mounted on a tripod. Each image was shot at ISO 3200, f/1.4 @ 5 seconds on a Canon 70D and a Sigma 100mm ART lens. Images stacked with DeepSkyStacker.
Some quick test images taken from my backyard.
It's nearly that time again for the webinar: Astrophotography 101: Getting Started Without Getting Soaked

This is a restacking of the previous image processed on just a portion of the overall image so that I could use the 3x Drizzle setting in Deep Sky Stacker to try and improve the resolution of the nebula.
Also tried a couple new tools in The Gimp for cleaning up noise, setting the black point etc.
The photo consists of 30x 20 second exposures at ISO1600 on a Canon T1i DSLR at prime focus on a 10 inch SN-10AT telescope using a light pollution filter. 10 minutes total exposure time.

This is the same stack of photos from my last star trails effort. 40 pics, this time the stars are aligned so the foreground seems to 'move', the tree branches as a result are blurred. Next time I'll try it without the foreground.

i used the software DeepSkyStacker to combine all the comet images into one; it lines up the stars, but that means the comet comes out as a streak.
First attempt at photographing things like nebulae. This was done with a K-1 with astrotracer on, 8 frames of 20-40 seconds with the lowly pentax-M 200mm/4 at 5.6. Processed in deepskystacker and rawtherapee
On some parts of the frame something seems to have gone wrong with the alignment.

A stack of 12 light frames at 10 minutes 800 ISO done by DSS as a 2002 pixel square crop via a custom frame to remove the annoying amp glow at the edges of the frame. The only PP was done via an auto stretch in AIP4WIN. I'm sure that I could do more processing, but I'm happy enough with this result. I will need to do some more reading on what I can do with the software before going back to it.
Something to note: Using PhotoMe software, I can see that the camera temperature ranged from 18C to 25C over the course of the session. I'm still not sure what to do about darks, as it seems the amp glow is always present, even after DSS is finished.
I have made a different image from this data with a custom rectangle on the nebula. See it here.

M81 and M82 are two galaxies that interact gravitationally. This interaction has triggered a star burst activity in M82 and NGC 3077.
Both M81 and M82 are spiral galaxies - although M82 was previously believed to be an irregular galaxy.
M81 is also known as Bode's galaxy and is situated 12 million light years away in the constellation Ursa Major.
M82 is known as the Cigar galaxy (due to obvious reasons) and situated at about the same distance from us as M81 in the Ursa Major constellation.
In this image we can see:
M81 / NGC 3031 : spiral galaxy (App Mag:6.94 \ App Size: 26.9' × 14.1')
M82 / NGC 3034 : spiral galaxy (App Mag:8.41 \ App Size: 11.2' × 4′.3')

The two largest asteroids, Ceres and Vesta, are heading for a close conjunction in mid July 2014. They are both too faint to see with the naked eye, but are easy targets in binoculars, near the fairly bright star Eta Virginis (which currently forms a nice triangle with Mars and Spica, as shown in this image). The asteroids will continue to move closer to each other over the next few weeks.
Incidentally, NASA's Dawn spacecraft is currently on route from Vesta to Ceres, where it will arrive in 2015!
For this image, I stacked 20 x 2.5 sec exposures (plus 10 corresponding dark frames) taken with my Canon 50D and EF35mm f/2 lens at f/2.8 and 1600 iso, using DeepSkyStacker.

This is a mix of two images, one with the nebulosity and the other with the colors.
The suburban skies of the Burlington, Ontario were cold, stable and reasonably dark on the evening of December 4th, 2018. The combination of good viewing conditions and a better-than-usual polar alignment on the tracker permitted me to capture and stack forty 30-second exposures of the Orion Nebula. I need to process this more, however I'm happy with the first cut.

Alrighty, here's another one from last night. The Pleiades star cluster. (M45). It's easily visible even to the naked eye, but imaging the object is usually required to bring out the whisp-like nebulosity.

The Rosette Nebula is a beautiful nebula shaped like a christmas wreath or donut by the stellar winds of the massive stars in the cluseter at its heart. The glowing pink is Hydrogen Alpha emissions from Ionized H2 gas.
It's a planetary nebula located about 1000 light years away in the constellation of Vulpecula. Like M57, it was created when a star similar to our own hit old age and puffed off it's outer layers.
Without a camera, just looking through the telescope, no colour is apparent. It just looks like a fuzzy patch faintly dumbell shaped, no sign of the outer shell.
The photo consists of 30x 20 second exposures at ISO1600 on a Canon T1i DSLR at prime focus on a 10 inch SN-10AT telescope using a light pollution filter. 10 minutes total exposure time. Photo stacked with Deep Sky Stacker. Cleaned up a little with Gimp.
I tried to take more care with this one, limiting the exposure length to try and keep the stars looking sort of like stars, although they are still kind of squiggly.
Stacked a series of 19 20 second images using deepsky stacker, Photoshop to stretch using levels adjustment and a removal of a gradient. Jupiter is the bright object, Antares is to the lower right. Images from Big Bend National Park August 2019.
Canon 50mm EF lens (MK I), at f/2.8, ISO 800. Five hand-tracked exposures (total exposure time 3m 15s), stacked in DeepSkyStacker and processed in Photoshop.
The colour gradient is caused by light pollution, which almost washes out this part of the sky from where I am.
