Andy,
Nice M83 out of your 6” newt and DSLR
Spiral arms have good detail and core is well exposed
Well done !!
Although one observation is colour seems a bit bland ?
Try Startools beyond just gradient removal , I think you’ll be surprised
Especially in the colour module using Scientific Aware , really works well with M83 gives it a lease of life in the spiral arms and core
Maybe if you image M83 again , drop your sub lengths to 3 minute and capture heaps more data , 10 minute subs IMO are way too long for a DSLR ( QE only 40% ) as your SNR will suffer greatly ( noise fest )
That 6” newt has plenty of light grab so don’t worry if your subs are a bit faint , just capture 50, 60 or 80 subs or more at 3 minutes and the detail will be there after you stack and stretch in Startools
I used my Canon 600D ( unmodded) for 4 years in my 6” f6 newt ( still use the newt ) and very rarely pushed 5 minute subs at my dark site
ISO 800 and 3 minute subs was the sweet spot for most dimmer objects , kept the noise floor down considerably ( except for summer nights )
Cheers
Martin
