Description

Trip to Atacama, Chile, May 2012

Shoot taken using a DSLR re-filtered camera @85 mm focal length f/4, mounted on an unguided Skypatrol mount, under a bright+++ setting Milky-Way.

I would have prefered Carinae nebula centered a bit more in the field of view ...

Object description

Wide-field view between the Running Chicken nebula (lamba-Centaurii) and the eta-Carinea complex.

Lying on the right-bottom part of the image, the open cluster IC2602, usually called "The Southern Pleiades".

Processing description

Pre-processing with DeepSkyStacker

Sigma kipping addition, 2 iterations, kappa=5

Processing with PixInsight

BackgroundNeutralization, ColorCalibration

StarMask production and stars size reduction using Morphology

HistogramTransformation

Masks production for nebula, stars, and LHE

HDRMultiscaleTransform to de-burn nebulae cores

LocalHistoEqualization for enhance contrast in the brightest parts of the image

Noise reduction using ACDNR with lightness mask, SCNR to remove remanant green

Saturation boost using CurvesTransformation, 3 steps : global (no mask), then nebula only, then stars only

Final Histogram correction (black point only)
