Further to my recent SHO version of NGC 2070 Tarantula I decided to process a synthetic LRGB version from my recent SHO data set using Startools.
Here the workflow to set up and load the SHO data set into the Compose module to create a synthetic LRGB image if anyone is interested…….,
Startools - SHO data set to Visual Spectrum Synthetic LRGB
Open Compose module. Set Luminance Color to L + Synthetic L from RGB, Mono.
Create a Luminance channel by loading Sii into R , Ha into G and Oiii into B.
Press Keep then Linear then Save into your nominated location and save as a tiff file ( eg: SHO Luminance.tiff )
Close Compose module.
Open Compose module. Set Luminance Color to L + Synthetic L from RGB, Mono.
Create a Red channel ( Sii + Ha ) by loading Sii into R, load Ha into G.
Press Keep then Linear then Save into your nominated location and save as tiff file ( eg: Red Sii +Ha.tiff ) Close Compose module.
Open Compose module.
Set Luminance Color to L, RGB. Load saved SHO Luminance file into Luminance channel. Load saved Red Sii + Ha file into Red channel. Load existing Oiii file into Green channel. Load existing Oiii into Blue channel.
Press Keep then Linear. Open image in AutoDev or Film Dev and process as normal When you hit the Colour module select the following Color luminance style - Style - Artistic Not Detail Aware LRGB Method Emulation - RGB Ratio CieLab Luminance Retention. Adjust saturation and colour bias to taste. Leave Matrix ( presets ) identity Off Save then move onto final modules and Tracking Noise Reduction
Its definitely not a bonafide LRGB image but Startools does a pretty good job to create a synthetic version.
