If I can make some critique (?) I am confused as to whether the detail in the galaxy is indeed real or instead been influenced by your processing..? At first glance there is certainly what appears to be some fine resolution but on closer inspection it doesn't look natural to me . Did you use deconvolution or perhaps wavelet like proicessing by any chance? Something in your processing has imparted a minimum filter/overdeconvoluted appearence to the finished result..?

The detail in the little companion galaxies is the best I have seen though and does look real.

Great work and long live the APO's

Thanks Mike - critique away mate - no probs at all!!

Yes, I enhanced the lum selectively with wavelet - the central region mostly to tease out some additional contrast. I normally do some selective wavelet or deconv to the lum - when the data is good. I'm always careful not to add or subract detail though (by referencing images from large scopes) but changing the detail a bit is generally unavoidable if you do any kind of sharpening. You could argue that I overdid it though - I'll have a look when my eyes are fresh - perhaps I'll also post the completely unsharpened version FYI.

I was quite surprised at the detail in the raw (stretched) image ... the smile on my face grew by the minute as I started processing. Definitely a testmanent to good optics (and good seeing).

Thanks for the feedback!

Cheers, Marcus
