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.
