IC1805 Heart Nebula in SHO (Adding another nights worth of integration time + reworked process for better colors (less is more))

Revision title: reprocessed with arcsinh stretch and blend star reintegration

process:
- 1x drizzle during WBPP stacking
- ABE, LinFit and EZ Softstretch on S,H,O Channel subs
- RGBCombination into SHO
- BlurXterminator, NoiseXTerminator and StarXterminator on SHO
- Starless image
.Luminance Channel: sharpen and increase contrast with BlurX, Curves, and NoiseX
.Ben Blanchan's SHO normalization script
.RGB Channel: Curves for gentlecolor shifting to more red and increasing brightness + saturation
- Merge L and SHO to LSHO
- Stars Image
.stretch via STF+Histogram (very bloated stars)
.then shift midpoint to very right to dim the stars
.curves reduction of bightness
- Merge LSHO with stars image and increase brightness again

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.
