IC 1795: A Colorful Fish Swimming Through Cassiopeia (John Hayes)

IC 1795: A Colorful Fish Swimming Through Cassiopeia

The Fish Head Nebula is a bright emission nebula with complex regions of dark nebula attached to the Heart Nebula complex located at a distance of 6,000-7,500 ly. This image was made using Ha, OIII, and SII narrowband filters and combined using the Hubble palette.

I struggled a bit to grab all of the data I needed to process this image through periods of wind and mediocre seeing. I wound up processing this data using 64 bit integrated data to insure that the processed data remained above any quantization limits and it worked out pretty well. I always struggle a bit deciding how to control the green cast in any HSO composition and this image was no exception. In the end, I went with with the green component dialed way back to produce the blue/yellow/orange variation presented in this image. Hopefully it works for you folks.

As always, C&C is welcome so feel free to let me know what you think...

John

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.
