Barnard 150, a LRGB Seahorse in Cepheus

Revision title: 3rd try same data - I think I need about 10 more hours of luminance data!

The Seahorse Nebula is a dark nebula found in Cepheus. The surrounding interstellar Milky Way dust only partially obscures the colorful background of stars. This particular image was separated into stars and starless images using StarXTerminator in the linear state; nebulosity color was not manipulated during conventional histogram stretching, so I was surprised by the resulting richness of colors of both the background and the nebulosity. Finally, imaging was done approaching and at full moon, so I was additionally surprised by the nebulosity detail despite the lunar light pollution and wildfire smoke haze.

Title: Improved MureDenoise, Improved Luminance image

Description: I was never happy with the color or the amount of "noise" in the first version -the original was shortly after converting to mono. I know for a fact I was not using MureDenoise properly, and the previous luminance image was over-processed. The 2nd version used a "super-Lum" integrating the LRGB for use as the Luminance image, and then separated stars from starless and thoughtfully stretched both before rescreening together in the non-linear state.

Title: 3rd try same data - I think I need about 10 more hours of luminance data!

Description: Never really happy with the first two versions, and it came back to over-stretching with inadequate data. Still not satisfied, but a bit better compared to the 2nd version.

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.
