NGC 2403 Intermediate Spiral Galaxy

NGC 2403 - is a spiral galaxy spanning 80,000 lightyears across, located 10 million lightyears away. (Our Milky Way is 100,000 lightyears across).

 

The galaxy can be found in the constellation Camelopardalis, close to the celestial north pole.

 

The image reveals pink regions of glowing gas that are active star-forming regions of ionised hydrogen.

 

New-born stars glow scorching bright blue among the dark dust lanes of the galaxy's spiral arms.

 

This picture was created by integrating two and half hours worth of two-minute exposures using my Celestron C11 telescope.
