Forming part of our local group of galaxies, M33 is approximately 3 million light years from earth. The central core of M33 is ringed with red star forming HII emission nebula and young hotter blue stars towards the outer arms.

 

Consisting of data collected over 3 years and of just over 22 hours of imaging time, this image was captured with an Altair Astro 6" RC and Atik 460ex camera.

 

Image acquisition in SGPro, calibration in Pixinsight and processing in CS5.
