About this image

Aproximately 15 hours of narrowband data taken over 3 nights (17, 19 and 25th November). Wanting to improve on my previpous attempt at this faint target I pushed the gain up to 300 from unity gain at 139 and took 10 minute subs. It was particularly pleasing to see the Oiii data appear as the blue colour in this HOO image which was noticably missing from my last try.
