Astrophotography – Imaging the Owl nebula and galaxy M108

The Owl Nebula (M97) (the little blue circle) is a planetary nebula located approximately 2000 ly away in constellation Ursa Major. It has already been discovered in 1781 by Pierre Méchain – a French astronomer. The cool thing about it is that there is a spiral galaxy M108 which is “close” to that nebula – at least from our perspective.

Total exposure~3h56min.

In a clear night I was able to shoot this image. With 3j56m the total exposure time is relatively long compared to other images. I did not use any flatfield images for the post-processing. Based on that fact I am quite satisfied with the result.

The image is also available in full resolution.

Clear skies!
