NGC 281 SHO & SynLum

Two nights of data on NGC 281 using RGB for stars and SHO for the nebulosity. I'm using ArchSinhStretch now for stretching the RGB images to highlight only stars. Then with a dark RGB for the stars, I blend this into the processed SHO using a screen blend in PixelMath. The narrow band is pretty much just SHO, but I used numerical factors for S and O to get the initial color balance more to my liking. I'm really starting to use Russel Croman's StarXTerminator and NoiseXTerminator tools, as like here, the star residuals were clearly less than StarNet2, and the noise reduction from NoiseXTerminator is so easy to use but super effective.

I had to work hard on this image to tone down the crazy oranges around the periphery of the nebula... lots of masking and curves transforms...

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.
