A Quick M42 under Moonlit Sydney Skies

Last night shaped up to be one of the best nights for imaging in the past 6 months or so with fairly good seeing conditions ( I could actually see quite a few stars for a change under Bortle 7/8 Sydney skies) and not much dew around either. Unfortunately a big old 90% waxing Moon overhead meant choosing a an emission nebula using narrowband.
I missed M42 last year so sneaked in a few hours this morning between 12.30am and 3.30am whilst skies were clear and relatively stable.
Really enjoyed this quick session
