Well after a summer of nothing but clouds we had a partially clear night at long last. I pointed towards M42 as a token effort.
Between wind and smoke despite being out for about 3 hours there is less than 1 hour of data in it. A token effort to say the least. As usually with the D800, bugger all Ha response and a very blue / purplish looking result. But a result none the less.
Glad I didn't pick a fainter target.
ISO400, 45 second subs, 8", f/6.3 and only pointed roughly south letting the poor autoguiding effort take care of the rest. Can you tell my heart wasn't really in it?
/EDIT: Any decent tips on how to process this one without cooking the centre? I tried in PI and every attempt to use HDR wavelet resulted in a flat looking rejected picture with a very grey centre.
