That's nice and smooth Chris! The core is nicely tamed too
Its a good feeling when results go your way, especially when you have to remember how to do things after a couple of cloudy weeks
I actually have Pixinsight crunching away on some M42 data taken from Sunday /last night too. Sunday was great! Very clear as you say and quite cool - good for the 60da
Looks like the light box was a success, well done!
