Heart Nebula Bicolor

Here's the first color image that I've produced with my mono camera since buying it in March 2017. We had a decent amount of clear nights here in NJ during the past month so I have actually had time to get enough Ha and OIII to make an image worth processing. I had been working on the Elephants Trunk and Crescent Nebula but since we got hit with a bad string of clouds I didn't even have time to get data on them before they started setting early. So that left the Heart as my object of choice and I'm quite glad I chose it.

I've been mostly following Kayron Mercieca's tutorials on Light Vortex Astronomy for mono data processing. As such processing was done entirely in Pixinsight. I've developed a real appreciation for PI doing this project. There are many processes I could still apply to this, namely deconvolution and tone mapping, but those will have to wait for now until I have a chance to sit down and really dig into this data. I used Jon Rista's Pixel Math tutorial for the HOO color blend and eventually settled on this one after experimenting with several different combinations. My biggest complaint is the blue gradient in the corners and the noise the black background areas. I could just not figure out how to get rid of those.

C&C very much appreciated. Thank you for looking.

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.
