NGC 1999 is at the centre of the nebula region right beside the Orion Nebula.
Telescope: William Optics ZenithStar 61 / ZS61
Camera: ZWO ASI533MC Pro
Mount: Sky-Watcher EQ6-R Pro
Filter: ZWO UV IR CUT 2″
Imaged over two nights from Brisbane, Australia. 280 x 180 sec subframes for a total imaging time of 14 hrs.
All processing in Pixinsight.
1. stacked with WDPP
2. dynamic crop
3. image solved for astrometric solution
4. removed gradient using Gradient Correction
5. correct colours using Spectrophotometric Color Calibration
6. initial noise reduction using NoiseXterminator.
7. Stretch using Multiscale Adaptive Stretch.
8. Remove stars with StarXterminator
9. S curve adjustments with Curves Transformation
10. Boost colours using masks, Curves Transformation
11. Removed any remaining green with SCNR.
12. Final noise reduction using NoiseXterminator.
13. Screen stars back in using pixelmath.
14. Final adjustments using Curves
