Helix Nebula NGC 7293 NB HOO

The Helix Nebula (also known as NGC 7293 or Caldwell 63) is a planetary nebula located in the constellation Aquarius.
The distance, measured by the Gaia mission, is 655 light-years.

The photograph was taken by Hugo Landolfi, in a backyard site, from an urban area near the city of Buenos Aires, called San Isidro, with a Bortle 8 sky and narrow band technique.

The data set that compose the image was taken with two cameras: a ZWO ASI 1600MM Pro and a ZWO ASI 294MM Pro in the months of July 2021 and February and March 2022.

Reprocessed in November 2022 using dynamic integration technique for narrow band.

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.
