The nebula consists mostly of ionized hydrogen. It appears red due to ultraviolet rays coming from a giant blue star near it that does not appear in the image (Gamma Cassiopeia), and the light blue color is due to the reflection of rays from the dust in the nebula, the Abu Dhabi-based International Astronomical Centre said on X.
The image was taken using the main observatory telescope with a diameter of 36 cm.
It consists of a compilation of 156 images taken with a hydrogen filter, 153 images taken with a sulfur filter, and 155 images taken with an oxygen filter.
Each image has a duration of 3 minutes, which is a total of 464 images, lasting 23 hours.
