2 Color Mixes on IC1795, the Fishhead Nebula

Here is the Fishhead Nebula, in classic SHO, and then a modified SHO with the Ha tamed down a little and the green supressed. I think I like the modified SHO version better, but it is a near thing for me, so I am posting both versions. This was taken over the new moon period in October. There was what seemed like a little less contrast in the sky for many of the nights, almost certainly due to fire smoke. But I am thinking that based on these results, still worth imaging.

The Fishead Nebula is a star forming region located right next to (or maybe as part of) the Heart Nebula, in the constellation of Cassiopeia.

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.
