NGC 3324 is a star forming region at the northwest corner of the Carina Nebula. It is called the Gabriela Mistral nebula, because of the resemblance with the Nobel Prize winning Chilean poet. It’s shown in the center of this image, with Eta Carina Nebula to the left and NGC 3293 upper right.
This is my 1st attempt at imaging & processing L R G B with the QSI683wsg-8. Here’s my PI workflow, I’m sure it needs much improvement but it’s a start… Comments and advice appreciated. (based on a sample workflow by Rogelio Bernal Andreo www.deepskycolours.com) Or comment on Astrobin:
Calibration of L / R / G / B with flats, darks & bias. Each channel calibrated individually
Dynamic crop
DBE of L / R / G / B
Star alignment of R / G / B to L
MMT of L to reduce noise
MT on B
Non-Linear transform of L
ChannelCombination of R / G / B to get RGB image
Same Dynamic crop to RGB as to L to preserve alignment
Background Neutralisation of RBG
Colour Calibration RGB
Non-Linear Histogram transform of RGB
SCNR to RGB
LRGB Combination
Morphological Transformation to reduce stars
Curves transformation / Saturation & contrast
Histogram Transform
AtrousWaveletTransform for noise / sharpening
Curves Transformation.
4:20Hrs LRGB

It amazes me when you say this is your first LRGB attempt! This has always been one of my favourite regions of the southern sky and I love the reflection nebulosity around the Gem Cluster, which is sometimes washed out in Ha composites. I could look at this forever!
