This is NGC 45 located in the constellation of Cetus, approximately 22 million light years away. It is situated close to the celestial equator making it mostly visible from both hemispheres. It has a low surface brightness and lacks clearly defined spiral arms like our galaxy, The Milky Way.

It was a challenging image to process. That bright star has a massive halo around it, spreading into the NGC 45. A closer investigation will reveal many galaxies in the background. That’s the stuff I like, all those tiny galaxies highlighting the vastness of the cosmos.

Lovely image Terry. I really like the amount of detail and colour you’ve captured, but especially your natural processing that makes it such an enjoyable view. Great work!

PS- the detail you get on those background galaxies is extraordinary. I’m led to assume you’re imaging from quite a dark location?

Cheers many thanks :thumbsup:



Thank you for the comment on my processing style Dave. I love the tiny stuff in the background. It highlights just how large the universe is. Your assumption is correct, it's dark.
