This is the Pinwheel Galaxy, M101, in a wide-ish field LRGB composite. Usually one would image this beauty at a slightly larger focal length, but this wider field puts the galaxy into a nice context. M101 is a large galaxy, quite comparable to the Milky Way. With a diameter of 170,000 light-years it is about […]
This is a HaLRGB composite of M106 with its companion NGC4217 and many small neighbours. Have a look at the full-size image to discover all the tiny galaxies in this field. The image is composed of 25 x 900 sec luminance, 16 x 600 sec RGB, and 19×1800 sec Ha exposures taken at the Deep […]
Following the plain H version, here the false-color HSO image of the Orion Nebula, M42. I went for a unconventional color scheme, which highlights the structure of the nebula outside of its main part… lots of dynamics. Exposure: H 16x60sec + 14x300sec + 8x900sec, S 11 x 1800sec, O 18 x 1800sec Date: 2016-1-17 Setup: […]
