Description

The Canon T3i sometimes gathers more noise than proper signal... Even though it was decently cold (-5C). So much that PI tools (TGV, ACDNR, MLT, etc) seem to be of no use as default values yield negligible improvement and forcing the parameters generates science fiction artefacts

So, just like Markarian's chain, this image is heavily processed (ahum ahum).

Short exposures as I did not guide (some kind of PC problem). And I assume my PA was so and so....

Wide angles are very nice. But do show limitations. Not sure 400mm focal length is ideal for this target. A full frame sensor with 600mm FL would probably give nicer results

(And thanks Ruben for pointing out that the first version was very bluish. I do love the blue but I admit it was exgerated :-). I straightened out the histogram somewhat)
