G'day Mike,
A superb image, one of many in your fabulous collection.
I'm so glad you finally joined us here on IIS.
We met recently at the SPSP if you remember.
I was wondering the reason why you used two different scopes for your Lum and RGB data?
I must say the core of NGC 4945 looks like it fluoresces with light in your image, obviously using the starfire for the Lum data helps enormously.
Just wondering why you didn't use it for the RGB data?
Once again welcome to IIS and I'm looking forward to many more wonderful images from you.
