Description

Late season M8 from lockdown central - My light polluted suburban backyard, Bortle 7 -Melbourne Australia.
A return to my narrowband roots, just 5+ hrs of data processed with the usual J-P Metsavianio tone mapping and a tweak or two inspired by Eric Coles Histogram balancing method.
Fortunately, it's a very bright target!
