I wasn't sure whether I should post this one or not because it's not my data. I only did the processing. Then I thought "what the heck", people might like to see it.
I swapped some data with a colleague in the US. He got the Tarantula and I got the Whirlpool galaxy. It's always been one of my favourite galaxies and I enjoyed playing with it.
If people think that this isn't an appropriate post for this forum I apologize in advance.
Cheers
Steve
