NGC 7380 (Wizard Nebula) October 2023 HaRGB

Not only is this my first attempt photographing the wizard nebula, it is also my first attempt at creating an HaRGB composite image. I did not use the traditional method of combining Ha data with full color data, where a monochrome blend between the red channel from the RGB and the Ha image is created, and then pasted onto the red channel in the RGB image.

To combine the two datasets, I instead set the Ha image to luminosity blend mode over the stretched RGB image with dust and scratches applied, then to get my color information back set another copy of the Ha image on top of those two layers and set the blend mode to lighten.

I'm not sure if the method to create an HaRGB image is the right way, however it still achieved the end goal of retaining RGB stars whilst adding the enhanced luminosity of the nebula structure which was almost non-existent in my full color image despite several hours of integration.

It will be interesting to see moving forward how hydrogen alpha data combines with full color data on other deep sky objects.

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.
