IC1805 & IC1848: Heart and Soul Nebula

Mosaic of the Heart and Soul Nebula. This is my first time doing a mosaic, but I think it actually came out really good and was surprised at how easy PI made it. I didn't originally plan for a mosaic, but I still had some time after capturing the Heart Nebula so I decided to manually align the Soul Nebula too. It ended up being about a 60% overlap between the two targets.

Pre-processing each panel in PI:
- WBPP for calibration, cosmetization and debayaring
- StarAlignment
- LocalNormalization using best image by PSF
- ImageIntegration using best image by weight as reference
- DrizzleIntegration using scale of 1 as anything else generates artifacts in the stars

Creating mosaic:
- DynamicCrop and DBE on each panel
- ImageSolver
- MosaicByCoordinates
- dnaLinearFit
- GradientMergeMosaic with CloneStamp to remove pinched stars

Processing in PI:
- DynamicCrop
- DBE
- PixelMath to split into Ha and Oiii layers
- EZ denoise on Ha
- LinearFit Oiii using Ha as reference
- StarXterminator on Ha and Oiii
- PixelMath to combine into HOO image
- EZ soft stretch Ha and HOO images

Postprocessing:
- LRGBCombination using Ha as luminance
- TGVDenoise
- ACDNR
- MLT to slightly sharpen image
- CurvesTransformation
- LocalHistogramEqualization with RangeSelection masks
- DarkStructureEnhance
- PixelMath to add stars back
- EZ star reduction
- final CurvesTransformation

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
