Description

An image I would never have thought possible from my light polluted Manchester UK garden. I also included OIII & SII data to see this galaxy in a different light to those normally seen.

I have given the average sub exposure times above as they varied a bit. The average SQM-L for the whole 2 year period was 18.6 and never got better than 18.98 which is very rare. So I hope this gives some inspiration to those who image from poor sites to give it a go.
