Here is a panoramic wide-field age of what I think is one of the most fascinating objects in the summer sky, the Cygnus Loop (kno wn as radio source W78 or Sharpless 103).Located in the constellation Cygnus, visually between e and z Cyg (the stars representing the eastern wing of the constellation), the Cygnus Loop is a Supernova remnant (SNR) nebula. Due to the wide portion of sky covered by the nebula (about 3 degrees in diameter), we often have a partial representation of that. Several portions of the whole object are individually classified in different catalogs.Some words can be spent about its distance from the solar system. Measuring the distance of this nebula (and also of similar objects) is very difficult, due to its large and increasing dimension and to the presence of interstellar dust between us and the SNR.According to the most recent and accurate Gaia measurements, the Cygnus Loop is about 2.400 light years away from Solar System; it is 130 light years wide in diameter and is expanding at about 1,5 km/h. The visible portion of the Cygnus Loop is named Veil Nebula; it's a cloud of ionized gas (typically hydrogen, oxygen, and sulfur).When a star dies, it can go out silently or in a spectacular explosion as a Supernova. It depends only on its mass. The supernova explosion scatters most of the star’s matter in space; it is the “supernova remnant”. This matter is also composed of heavy metals such as gold, magnesium, etc.; those heavy elements can be reused in stellar formation processes and contribute to the creation of planetary systems. So, we can say that the Earth, and ourselves, are made of stellar matter.The picture was taken in 5 nights in 2023, June in my home garden in Cordenons, under a sky Bortle 7-8 (sqm max 18.25).Total integration 9h20m of 32x600” narrowband shots (H-alfa + OIII) and 48x300” broadband shots (R+G+B)

Title: Cygnus Loop Eastern Veil starless

Description: This starless version includes the nebula's east shield, cropped from the wide field image.
The Bat Nebula is one of the objects that led me to get passionate about astrophotography. Known as IC1340 is part of the Veil Nebula’s Eastern shield (also named Eastern Veil). The Eastern Veil includes IC1340 and NGC 6992-6995.

Title: Cygnus Loop Pickering's Triangle starless

Description: In this picture (a crop of a wider field), we can see Pickering’s Triangle and the two brighter knots known as NGC6974 and NGC 6979. The triangle is relatively faint and was discovered photographically in 1904; it shows the typical filamentous structure of the whole Nebula.

Title: Cygnus Loop Western Veli starless

Description: This picture is the last of a portion of the Cygnus Loop. The Western Veil, consisting of NGC 6960 (The Which’s Broom, or Lacework Nebula, or Filamentary Nebula), lies in perspective near the foreground star 52 Cygni; this is a giant star with an apparent magnitude of 4.22, at about 291 light years away. 52 Cygni is probably a Horizontal branch star (a star having a mass similar to the Sun that’s going to the end of its life).

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.
