Barnard 72, the Snake Nebula
A new image produced as a collaboration with me and Eric Recurt. The data is shot from his observatory at Tenerife. The Observatory locates at 2400 m altitude and at 28 degrees North. The site has excellent seeing conditions, 0.8 " on average and can be below 0.3 "

INFO
The Snake Nebula (also known as Barnard 72) is a dark nebula in the Ophiuchus constellation at a distance of about 650 light years. Barnard 72 lays at front of the Milky Way star clouds from the north-north-west edge of the bowl of the Pipe Nebula.

A new image, the Witch's Broom Nebula
This is my second photo for this season from my observatory. It's a detail of the veil nebula supernova remnant, as was my first light photo for this Autumn season, the Pickering's Triangle. This is a two frames mosaic image, exposed on several nights between September 10. - 27. 2015. Total exposure time is about 11h.

Astro Anarchy gets published
The Cnet published an article about Messier 31, the Great galaxy of Andromeda, photo.
Photo of Messier 31 is produced by collaboration between David Lane and me.

Messier galaxies, M81-M82, with integrated flux nebula
A new collaboration image with David Lane. Beside beeing a deep sky astrophotographer he is also a master of landscape astrophotographing, please, have a look at his homepage: http://www.davelaneastrophotography.com/
Image acquisition is made by David Lane. He sent a massive amount of data to me to process and here is the result, Messier galaxies 81 and 82 with a large amount of dim integrated flux nebula at front of them.
Total exposure time is around 40 hours with the William Optics GT81 telescope and SBIG STL-1100 3 CCD-camera.
