Beating in the body of the mythical queen of Aethiopia, Cassiopeia, is the Heart Nebula. Nearly 200 light-years across and 7,500 light-years from Earth, this bright emission nebula spans about 2 degrees of the night sky, an area about four times the diameter of the full Moon. The young, massive star cluster at the center of the Heart energize the surrounding gases dominated by hydrogen, with lesser measures of oxygen and sulfur.

As a bonus in this project, the planetary nebula, WeBo 1, is also present beneath the Heart in the bottom right of the frame. It is a peculiar object with a young barium star surrounded by a ring-like planetary nebula.

The night sky has been blanketed by marine overcast for the last two months. While I know that it is coming every summer, I still find the inability to collect data frustrating. Fortunately for me, I am a “packrat” and have a 5-terabyte drive filled with data collect over the last few years. This image came from those data, collected in the fall of 2019. I was fortunate to have three night in a row of clear skies and collected nearly 30 hours of data in total, 20 hours of which was excellent Ha data with HFR ranging from 1.8 – 2.2.

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.
