Western Veil & Pickering's Triangle

This is a large supernova remnant, an expanding cloud of shocked gas, born of the death explosion of a massive star. Light from the original supernova explosion reached Earth over 5,000 years ago. This is the western section of the veil nebula complex which spans over 3 degrees of sky.

 

The weather has been pretty miserable here lately so thought I'd rework this data from last year a bit and added some star colour from the Canon 450D that I didn't get around to doing last year. Its based on the right hand panel from the original mosaic at:
