I love the detail of narrowband imaging!

I don't love deciding color palettes and blending methods!

In this image, I have uploaded both my custom HOS palette, as well as SHO palette.    I chose HOS because it provides a unique look into the Sulfur structure of this area that can easily get overlooked with SHO. These areas that particularly pop are to the right of the Bubble nebula, 3 or so filamentary structures jutting out towards the right.   There is also similar structure near the top of the base of Lobster Claw.     When you roll over the image, you will see the SHO revision mutes those structures.   Unfortunately as a byproduct of this blend, the Ha and Oiii structure do not blend as well.    You can notice this when you glance at the depth of the Oiii and Ha in the claw in SHO.    This depth is not nearly as significant in the HOS version.

The moral of the story is different palettes provide unique looks on the same data. I had an incredibly hard time deciding how I wanted to present this dataset, so I leave you with BOTH versions.    The differences in structure really stand out thanks to the rollover feature.

Let me know which one you enjoy more! SHO narrowband, while simple, is my weakness when it comes to astro.

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.
