Heart & Soul Nebulae (Mosaic) in HST* Palette

This is a shot of IC1805 (The Heart Nebula – also Sh2-190) and IC1848 (The Soul Nebula – also Sh2-199, LBN 667). Located between 6150 light years for the Heart and 6550 light years for the Soul nebula from earth, the complex is located in the Perseus Arm of the Galaxy and can be observed in the constellation Cassiopeia. Both objects are emission nebula made of glowing gases and dark dust lanes.

*HST palette is accomplished by combining sub frames using three narrowband filters that capture light produced by glowing hydrogen (Ha), oxygen (OIII) and sulfur (SII) present in the nebula. Green is assigned to hydrogen, blue to oxygen and red to the sulfur.

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.
