Melotte 15 - Heart of the Heart Nebula

The Heart Nebula is a great target object as it is full of detail. While the Ha data is fairly bright, the S2 and O3 frames are pretty weak. This Hubble pallet image is composed of 8 subs in each SHO filter - 15 min Ha and 20 min S2 and O3.

Additional subs in January allowed me to improve the processing. I took the approach of doing more processing of the master S2, Ha and O3 subs before combining to make the color image. This helped make the overall color more "realistic" and reduced the noise in the final image.

Originally imaged in November of 2016, I reprocessed the image in Sep 2022 using a lot of new PixInsight processes. This resulted in a better image with some star reduction to make the nebulosity stand out a little better.

December 23, 2022 -- Applied BlurXTerminator and NoiseXTerminator to the "final" image. The resulting image's noise was noticeably reduced and the low leverl details improved.

Description: This third round of processing is based on obtaining additional subs. Now a total of 16 per SHO filter. Would like to get to 20 subs in each filter but will have to wait until next year.

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.
