C/2011 L4 is getting dimmer but easier to find as it approaches the Andromeda Galaxy (M31). Photographed at 8:18-27 pm on April 2 in Cambridge, MA, USA. Stacked from 109 frames of 3.2" exposure each at 190mm, F/5, ISO 1600 using DeepSkyStacker's comet mode. The color bandings in the background came from low clouds and my attempts to manually correct lens vignetting as I did not shoot flat flames for this.

After a long night at Joshua Tree last night, here's the first result! The open star cluster, NGC 2244 and the Rosette Nebula (Caldwell 49). A large star forming region in the direction of Monoceros. New stars are being formed and exerting radiation pressure scultping the surrounding nebula. :)

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.

Again, the stars are rather poor, with coma and bloating, but I was pleased with the spiral structure of the galaxy.

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.

M102 in Draco. There is some controversy over whether Messier actually observed this galaxy or it was an accidental duplication of M101.
This tiny galaxy is actually a spectacular edge-on galaxy with a magnificent dust lane as seen in professional images. I really only took this image as it's a Messier object I haven't imaged before, it's not very exciting at this scale!
