Description

Astrophotography newbie experiment of the day.

60 best subs from previous attempt (approx 1hr).

Preprocessed in LR to apply lens profile corrections and worst of CA. Idea being that proper Nikon profile data is going to do a better job of flattening out image and removing vignetting than guesswork in PI.

Output from LR as TIFs and stacked in DSS (tried NEF and DNG but DSS doesn't seem to pick up applied corrections - just loads original raw data).

Turned off calibration in DSS to see if PI would do it better.

Processed stacked image in PI. Began as an alarmingly red image due to light pollution (DSS calibration disabled) but mostly DBE sorted it.

Applied some ACDNR in PI - quite like this over LR's noise reduction as easy to apply a mask to protect nebulas etc.

Used PI SCRN to strip out green pixels (not that there were many - red being more of an issue).

Dumped image back to LR as 16bit TIF (LR4 loads 32bit TIFs but not correctly it would seem).

Did final curves and levels adjustments in LR.
