Fish Head Nebula (IC 1795) - Bortle 2 - Animas, NM

Revision title: HOO - Hubble Palette

Getting after the winter Nebula from DSP Remote in Animas, NM. The Fish Head Nedula is one I've wanted to photograph for a while - got a few good nights in with the Askar 130PHQ and ASI 2600MM. Then had some fun playing with different combos of HSO, SHO and HOO + Hubble Palette. Which version do you like the best?

The goal here was to play with the different palettes and get a sense for how they mix a nebula like this. My general process:

PixInsight WBPP to stack data from the three different filters
LRGB Combination with the different color/filter choices
PixInsight Spectrographic Color Correction w/ narrowband parameters
EZ Processing Suite Soft Stretch
Russel Croman's BXT and then NXT
Russel Croman's SXT and extract the stars luminance channel for later
Optional: Narrowband Normalization if processing for Hubble (e.g. HOO -> Hubble)
Curves to taste (no masks, just saturation and then per channel)
Recombine the stars and starless images
EZ Processing Suite Star Reduction (using the stars luminance channel)
Save as PNG

Title: SHO

Description: After working on the HSO initial draft, I tried doing a SHO pass (more like hubble palette). This was the result after a bit of time with curves.

Title: HOO

Description: After playing with SHO and HSO, decided to try good old HOO and see what it gave me.

D

Title: HOO - Hubble Palette

Description: And finally I tried the NarrowBandNormalization process in PixInsight and did an HOO -> Hubble Palette conversion. In addition, I did a HDMRT on this version to get the middle of the nebula to be less washed out and more scaly (like a fish!).

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.
