HORSEHEAD NEBULA IC434 IN RGB w/10% HA LUM

This is an RGB image project with a 10% HA blended in with the PIXINSIGHT LRGB Combination Module.

After getting my lunch eaten on the Pacman Nebula, I went back and revisited my data collection methods. I live under 19 to 19.5 skies and my color has never been good.

This target was nice and bright. Shot Lum, HA, Red, Green, and Blue. Combined as RGB, HaRGB, LRGB. Finally tried 10% HA Lum in the Pixinsight LRGB combination and that looked just right.

HA = 7 * 5 MIN, used as 10% LUM

RED = 45 * 2MIN

GREEN = 45 * 2MIN

BLUE = 45 * 3MIN, Only 29 passed the RANSAC combination in PI.

My dithering settings need to be set highter to get past some column defects.

Image was shot with a NAB SBIG 1603ME, hence the blooms.

Feel this was good progress and was able to apply the lessons learned on my NGC281 Narrowband Project.

NGC 2023 showed more than just blue with the RGB technique.

Will probably shoot my HA and try another version of this image now that I have some nice color to work with.

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.
