NGC300 Galaxy in Sydney with 6” newt

I was probably stupid or desperate last night trying to Image a dim Galaxy with my little 6” f6 newt under a 50% waxing moon and Sydney Bortle 8 skies plus a 35km/hr westerly wind but here it is anyway
NGC300
32 x 2 minute dithered guided subs
15 x darks
6” f6 Bintel newt on a HEQ5 mount
Canon 600D with Baader coma corrector
Had my little home made DSLR cooling fan running and sensor temperature went from 22 deg C at the start down to 16 deg C , stayed around 16 to 18 all night ( hopefully it will help during summer nights )
PHD2 guiding ( 1.50 to 1.80 arc sec error , dithering was knocking the guiding around a lot and took up to 1 minute to fully recover even increasing the Dither settle to 0.65 )
Stacked in DSS
Processed in Startools
Subs didn’t even show anything , just a bit of the core
Heaps of noise
Focus was out to blazes
Larger stars hex looking probably due to focus
Lucky to get any sort of image at all !!
Thanks for looking , bad comments welcome
