Cygnus loop supernova remnant (SH2-103)

The veil nebula (SH2-103), in the constellation Cygnus. This spectacular emission nebula is a supernova remnant, left over by the explosion of a massive star, about 2400 lights years away. This is my first attempt at a mosaic (2 panels): the exposure time of each panel was 3h20, with a dual band filter (Ha, OIII) and a small refractor (400mn focal length). Red and blue colors comes from hydrogen and oxygen ionized gas respectively.

From my backyard, in Herault (France).

-------------------
Les dentelles du cygne (Sh2-103) : nébuleuse par émission, qui a pour origine une supernova (c'est un rémanent), dans la constellation du cygne. Sa taille angulaire dans le ciel est particulièrement imposante (presque 3°). Sa distance estimée (sujette à débats) est de l'ordre de 2600 années lumières. L'objet résultant de cette explosion (étoile à neutron) n'a pas encore été identifié. Mosaïque de 2 photographies de 3h20 de pose avec un filtre dual-band (image HOO).

Depuis mon jardin, près de Montpellier.

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.
