The sky was pretty transparent such that a camera can just record the Milky Way in an urban sky. This is three 1-minute exposures stacked with DeepSkyStacker

Comet Lulin from my driveway. This version used the comet's coma for alignment, so the stars are trailed by the comet's motion. Focus was a bit off, too.

The same 12 exposures, but this time I got hold of Deep Sky Stacker and used that to register and stack all the images. It chucks out a 32-bit TIFF, which I tweaked a bit to produce this image. I'm impressed - pretty sure that's a dust lane just above and right of the nucleus.

M13 - The Great Hercules Cluster. This 11.65 billion year old formation of stars is one of the most impressive globular clusters in the northern hemisphere. Containing over 300,000 stars packed into a 145 light year sphere, the center of this object is 500 times more concentrated than its outer perimeters.

Did another round of shoots after midnight. The earlier shoot ended prematurely by clouds. At the time I was shooting this series of shots, Sagittarius was about 60 plus degree in the sky and night sky is reasonably clear of clouds & haze. The camera was titled towards the zenith region.

Seen over Otmoor (UK) on the night of Sunday 19 July.
This is a stack of 68 frames at 100mm f4.5 and 2s - using DeepSkyStacker.
You (well, I!) can just make out the ion tail going straight out, slightly to the left of the diffuse, curved dust tail. The sky doesn't get super dark around here, so it was hard to get enough signal - plus on reflection I should really have used my f2.8 100mm lens rather than the 100-400mm!

A wide-field view showing the area between delta and epsilon Cassiopeiae that contains the open star clusters M103, NGC663, and NGC659 (see the image notes for locations). The bright star to the lower left is delta Cas, while epsilon Cas is out of the field of view to the upper right (celestial north is off toward the lower right). M103 is one of the smallest and most distant open star clusters in the Messier Catalog and was the last object that he added to the list.

I wanted to see how much detail I could capture in Orion without a tracking mount. I was surprised to find 5 seperate nebulas in this image. This is a stack of about 105 pictures each shot at 4 seconds, f4, ISO 8000 with a Takumar 135mm f2.5 lens. It was then cropped about 50%. One of these days I'll get an astrophotography mount so I can capture even more. To give you an idea of what else is in that constellation, check out this picture with nearly the same field of view: www.flickr.com/photos/28192200@N02/5776855550/
100x 15 sec exposures using ZWO ASI1600MC camera and AltairAstro ED triplet refractor. Stacked in DeepSkystacker and processed in Adobe Lightroom. No calibration frames or autoguiding.
The first picture taken through my AltairAstro 3" refractor on 30 Nov 2017. 70% moon so well pleased !
M42 is a diffuse nebula in the Milky Way approx. 1350 light years away and is the archetypical stellar nursery with stars emerging from clouds of hydrogen gas and dust. The bright area consists of a cluster of young stars called the Trapezium (overexposed in the photo in order to bring out the surrounding nebulosity).
This is M33 after a long time of processing. You can see more about this galaxy on Wikipedia.
The original lights came from the evenings of September 18 and the night of September 23-24, 2009
Taken with my Pentax K10D camera with the Stellarvue SV4 scope, operating at Prime Focus. A field flattenter was also used as well as a Baader Moon and Skyglow light pollution filter. Tracking was done with the Orion Starshoot Autoguider using a Stellarvue SV 70 ED. The DLSR in-camera noise reduction was turned off. Most shots were done with using the Pentax remote control software to do bulb interval shots. I allowed about 2 minutes of time between shots to give the camera a chance to cool off and for the batteries to recover.
Most of the darks were recorded well after the lights in an effort to help understand and control the noise that is generated by this camera. I learned that I had to be vigilant regarding IR light getting into the camera when making this library of darks. Also, it appears that the telescope body itself seems to act as a heatsink for this camera, making collecting darks requiring connecting the camera as if it was in the field.

Processing was with PixInsight LE 1.0 using the instructions provided by Rogelio Andreo regarding gradient subtraction:
blog.deepskycolors.com/archivo/2010/05/
Further processing was done via the tutorial at this page from David Nash's website:
www.davesastro.co.uk/techniques/pixinsight_tutorial/index...
I'm extremely happy with how this image turned out. I know that there are a few gradients still showing up. Still, this is much better than I've been able to get from what I've always known was good data. The missing bits were getting a library of decent darks and flats and bias frames to give DSS some meat to chew on.
Finally being able to follow what is happening in PixInsight really helps as well.
Now I'll try to fill in the holes in my other data from last year and I'll see what I can get!
Quelques tentatives réussies de capturer la comète C/2012 S1 ISON. Malheureusement, la queue ne se détache que très mal du fond du ciel. Les raisons peuvent être le début de l'aube et la présence de la Lune presque pleine, bien qu'à l'opposé. Je tenterai de combiner les 17 fichiers d'assez bonne qualité avec Deepskystacker ou IRIS.
Some attemps of capturing Comet C/2012 S1 ISON. Unfortunately, the comet's tail doesn't detach that clearly from the background sky. Reasons can be the approaching dawn and the almost full Moon, although it was far in the sky. I will try to stack the 17 good files I made in Deepskystacker or IRIS.

I've recalibrated and stacked and worked this image a few times since I first attempted it. Each time I come back with one more bit of knowledge.
This time, I'm still calibrating with Maxim. What's new is that I'm calibrating with 2C increments. Thus, for the 10 lights, there's two sections for calibration. This significantly reduces the over and undercorrection that I was seeing before. Also, it makes the post process a lot easier to manage.
Same details as before:
10 lights total, each at 600 seconds and 400 ISO.
