In the Perseus arm of our galaxy we find two spectacular nebulae, the Heart (IC 1805) and Soul (IC1848 ) nebulae. Located around 7,500 light years away from us both cover a wide region of the night sky, in the Cassiopeia constellation. Several full moons could fit inside this image.

Both nebulae have high emission on the red spectrum and especially in the H alpha line. With the use of this filter we can capture its structure.This image shows the Heart Nebula and is the result of combining a 12 pane H alpha mosaic and a 8 pane RGB mosaic. All the data was captured back in 2017 and I have been working with it for several years until I got this result. The new processing techniques and programs have played a relevant role in the high definition achieved. Faint planetary nebulae can be seen in the details of this image. I hope you enjoy the image as much as I've done. Thanks for taking your time on this site.Image details:

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.
