Had yet another go at processing my ancient data. Slightly less aggressive crop than before and took a bit more time on curves adjustment in Pixinsight. Might have slightly overdone the star reduction as they look a bit sharper/more artificial than the nebula. Anyway I continue to be blown away with what can be dragged out of a mere four hours of integration on a 15 year old camera.

Re-edit of this mosaic using PixInsight 1.8
2-tile mosaic covering the Pipe Nebula and most of "The Kiwi", plus a bit of Sagittarius showing Messier 8 and 20. And as a bonus, Saturn is the bright one bottom centre. :-P
Later in the season I hope to shoot 2 more tiles above, below and to the left of this image, covering a nice big chunk of this amazing region of the sky.
Each tile is a stack of 10 x 180s images shot at 120mm focal length, F4.5 and 640ISO.
Humidity was very high, and for the last few shots I was in thickening fog moving down from the hills ...

The Pleiades, also known as the Seven Sisters and Messier 45, are an open star cluster containing middle-aged, hot B-type stars in the north-west of the constellation Taurus. It is among the star clusters nearest to Earth, it is the nearest Messier object to Earth, and is the cluster most obvious to the naked eye in the night sky.
The cluster is dominated by hot blue and luminous stars that have formed within the last 100 million years. Reflection nebulae around the brightest stars were once thought to be left over material from the formation of the cluster, but are now considered likely to be an unrelated dust cloud in the interstellar medium through which the stars are currently passing.

It's been a year since I have done astrophotography but the last 2 days of cold and crisp weather has provided a perfect opportunity to get out and image again. This image of the Rosette Nebula (also known as Caldwell 49) was taken from the garden in Aberaeron over two successive nights. The nebula is a H II region located near one end of a giant molecular cloud in the Monoceros region of the Milky Way galaxy. The open star cluster NGC 2244 (Caldwell 50) at its centre is closely associated with the nebulosity, the stars of the cluster having been formed from the nebula's matter. The cluster and nebula lie at a distance of 5000 light-years from Earth and measure roughly 130 light years in diameter (to put this in context, light from the sun takes just 0.000015561 light years, or 8 minutes, to reach Earth!) The radiation from the young stars excites the atoms in the nebula, causing them to emit radiation themselves producing the emission nebula we see. The mass of the nebula is estimated to be around 10000 solar masses.
This image comprises 88 x 3 minute images stacked and processed to generate a final image.

Looking back over some old data I wanted to see if I could improve on my last process from 2011. I used the new TGVDenoise process in Pixinsight and some great techniques from Gerald Wechselberger on how to push background dust and nebula without effecting stars.
You can watch the video here pixinsight.com/forum/index.php?topic=5384.0
This was 8.5 hours of LRGB data captured in September 2011 with my Orion ED80TCF and Atik 314l+, processed in Pixinsight and CS5.
A cropped widefield image of the Eagle Nebula, with the "Pillars of Creation" visible in the Nebula. The Eagle Nebula is catalogued as Messier 16, M16, or NGC 6611, and also known as the Star Queen Nebula and The Spire. M16 is a young open cluster of stars in the constellation Serpens.
The Eagle Nebula is part of a diffuse emission nebula, or H II region, which is catalogued as IC 4703. This region of active current star formation is about 7000 light-years distant. A spire of gas that can be seen coming off the nebula in the north-eastern part is approximately 9.5 light-years or about 90 trillion kilometers long.
Both the "Eagle" and the "Star Queen" refer to visual impressions of the dark silhouette near the center of the nebula, an area made famous as the "Pillars of Creation" photographed by the Hubble Space Telescope. The nebula contains several active star-forming gas and dust regions, including the Pillars of Creation.
The cluster associated with the nebula has approximately 8100 stars, which are mostly concentrated in a gap in the molecular cloud to the north-west of the Pillars.
The size, distance and age of the Universe is far beyond human comprehension. The known Universe is estimated to contain over One Billion Trillion stars, many with planets just like our star the Sun.

About Emission nebulae:
Emission nebulae are glowing clouds of interstellar gas which have been excited by some nearby energy source, usually a very hot star. The red light seen in this picture is glowing hydrogen captured in the Hydrogen-Alpha (Hα) Infrared wavelength of light at 656nm.

Hi,
Here is one of my first astrophotograph of the deepsky I took at prime focus of my newtonian telescope with my canon T3i camera (unmodded)
It is a 10-image-stacked picture of 30 seconds each.
Both staking and processing were made by a friend using PixInsight sofware. Thanks to him :)
It is actually an update of my previous version inwhich I had used Deep Sky Stacker freeware and lightroom. Click here.
So, how to find the difference between PixInsight and DSS/Lightroom ?
We clearly see the powerful process of PixInsight !
Thanks for reading ;)

The Elephant's Trunk Nebula or IC 1396 as it is otherwise known, but never with such a wide field of view, at a distance of around 2400 light years from earth and is mainly illuminated by a single bright star. It is thought that this region of space is home to a pretty young star forming region.

I followed a Siril post-processing tutorial and got more interesting results than my initial random effort. Siril is the poor man’s Pixinsight!
Astro-tech AT60EDP 60mm f/5 refractor; ASI533MC Pro; Antlia quad narrow-band filter with an UV/IR cut filter (making it essentially a dual band filter); iOptron HEC29. 61 two-minute light frames; camera cooled to 0-degree C. Gain 130; Offset 40. Processed with Siril with calibration files; tweaked with Photoshop.
Lots of stars. Cygnus is smack-dab in the middle of the Milky Way. It’s a sight to behold at a dark location on a clear, moonless night. The blue and gold binary stars at the “head” of the swan, known collectively as Albireo, are the unofficial stars of UC Berkeley. Go Bears!

We have all seen Messier 110 (M110 or NGC205) many times, and many of us have probably never realized it. It has always been hidden off to the side with its larger neighbor, the Andromeda Galaxy. This fuzzy elliptical ball hovering over (or under, depending on your perspective) Andromeda, is, in fact, another galaxy called M110. If you look close, you can see some dark patches near the central part of the sphere. This galaxy is classified as a peculiar elliptical galaxy because of these dark structures and signs of recent star formation. It is hard to think about this small fuzzy ball of a galaxy containing over 10 billion stars!
