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.
