IC1805 Heart Nebula (Narrowband SHO)

A new version of the Heart Nebula.

Wanted to come back and give this one more time on target. I'm pretty happy with the framing and the color balance, particularly in the revised version which also has a bit better contrast and sharpness than the original version; I'm still figuring out how to process these things, so it's all... A process.

(Philosophically, I like to take a light touch to these things, so I'm willing to accept a bit of noise, etc., in contrast — pun intended — to introducing artifacts to remove it. But I'm still mostly struggling with getting a good luminance channel to work with in narrowband-only images. And I could certainly take more care to get cleaner stars, they really are kind of awful here.)

Description: Reprocessed using different methods; more contrast, better sharpness, and I actually prefer the deeper colors. Some darker detail isn't as prominent, though.

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.
