Here is a results with 95 subs (cropped and downsized by 50% to bring within file size limit). Outer details can still be improved with more data but I'm giving up for now as I kept getting 2-3 times more guiding errors in RA compared to DEC resulting in oblong stars and less sharp details in the centre compared to my earlier images with Quattro 10.
Cheers,

Thanks John,
Your image look impressive !!
Your Quattro scopes are at f4 so you have significantly more aperture and faster light gathering capability than my smaller slower 8” f5 Carbon ie: more detail for less integration time.
I’m currently gathering more Ha data so I can just do more experimenting with processing, hopefully I can improve SNR even if it’s only up to 5% or thereabouts
See how we go ……,
Cheers
Martin
