About this image

I really tried to get this done for the march observers challenge - sadly missed it

This was really tough from where I live in London - Bortle 8

I captured 26 hours total but there was so much noise and light pollution, my final stack was almost useless - and currently don't dither so there is walking noise as well

After trying to process it in different ways - the end result was far below what i would be happy with

I finally relented and decided to stack less hoping that the noise and light pollution would have some less affect

Luckily it did and here it is - 15 hours integration

Also found in this image are the galaxies NGC3134 @ 235 Million Light Years, IC591 @ 130Million Light Years, and NGC3153 @ 115 Million Light Years
