Here's the central region of the Heart nebula (IC1805) in Cassiopeia, also referred to as the Heart of the Heart! Despite being almost invisible to the naked eye, the Heart Nebula has an angular size of 1x1 degrees, about 2x2 full Moons! With short focal lenses, when the whole nebula fits the field of view, this object appears heart-shaped; with longer focal telescopes, the nebula does not fit inside the field of view, and it is only possible to image its core. Last Wednesday night, with the sub-zero temperatures that have hit the UK I literally froze to take this image! The picture that you see here is a false color HOO narrowband composite obtained by combining 3.5h acquisitions for both H-a and O-III filters.

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.
