M42 Orion Nebula Sydney (Additional Data)

November has delivered so far with 10 clear nights and seeing generally ok.( The most out of all months this year in Sydney with a week to go )
Captured more data on M42 last week to add to my existing image ( a total of 7 hours now over 3 nights )
Definitely some subtle improvements but there is a point of diminishing return especially with OSC under Bortle 7/8 skies ( A Mono and 3nm filters, totally different story I suspect regarding data )

Managed to expose more of the Trap without short subs and fiddling around with Masks and Laying etc… ( Startools is magic )

Really get the most out of Spatially Variant PSF Deconvolution ( SV Decon ) , brilliant module and I believe Ivo is working on a further improvement for version 9 where sampling stars will be easier.

6” f6 GSO Bintel Newt
Skywatcher EQ6-R pro mount
ZWO 2600MC cooled to -10C , Gain 100
TS GPU coma corrector
Antlia ALPT OSC 5nm Duoband NB filter
142 x 3 min dithered guided subs
40 x 3 Flats ( new flats each night )
60 x Bias
EQMOD, Stellarium, APT
PHD2 Multistar guiding ( 0.55 to 0.65 arc sec total )
Stacked in DSS ( multiple nights stacking using reference frame )
Processed in Startools V1.8 Compose OSC Linear data sets

Synthetic Luminance version
Some OSC SHO versions using matrix

Thanks for looking
Comments welcome
