M33 - Triangulum galaxy

Embergeralm, Austria

Here the galaxy M33 with many HII-regions of its own could be seen in the border of Triangulum and Pisces. The image was taken with an SBIG STL11000 and a TEC Apo refractor (140mm/f7 focal length 980mm). RGB filters were used from Astronomik. Exposure times were 6x10 mins with the red filter. The green images were exposed 4x10min. The blue component was artifical added afterward with help of software in form of doubling the green layer. Additive exposure time is therefore 100 mins.
