Good to see some shots from you Brendan, had been wondering where the data had been going
Omega Cent looks good. A bit soft and illongated on the edges, typical of WO gear from my experience. Centre is nice and sharp. Guiding looks perfect as per usual.
Not sure how you've ended up with the colour gradients so extreme in M83! .. the centre being more netural-green, then going through red-orange to the edge which is blue-violet! Bizzar, I've never seen such gradient of colour before?
.. quite an accomplishment perhaps
Detail in M83 its self looks great. How about a crop image showing more detail in M83? Looks like there's plenty of detail there to show.
