This photo shows two nebulae in the constellation of Auriga: the Spider Nebula (IC417 or Sh2-234) and the Fly Nebula (NGC1931 or CED 43).The Spider Nebula is an emission nebula that is located about 10,000 light-years away from Earth and has a shape that resembles a spider. Its brightness is mainly due to the action of the ultraviolet radiation of a massive star of spectral class O, which ionizes the hydrogen and other gases present in the nebula.The Fly Nebula is a reflection nebula that is located about 7,000 light-years away from Earth and has a shape that resembles a fly. Its brightness is due to the reflection of the light of four young and hot stars of spectral class B, which are located at the center of the nebula. The Fly Nebula is also an HII region, that is, a zone of star formation, where you can observe Bok globules, clouds of dust, and gas that can collapse under their gravity and give rise to new stars.The photo was made using the Foraxx Palette, a color combination that uses red for the H-alpha band, green for the OIII band, and blue for the SII band. This palette is a variant of the Dynamic SHO Palette, which uses a processing technique that emphasizes the colors and details of the nebulae depending on their chemical composition and their temperature. The Foraxx Palette creates a very impressive and artistic visual effect.The acquisition was made from the garden of my house, under a Bortle 7-8 sky.

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.
