M17 Omega Nebula

M17 Omega Nebula The Omega Nebula (also known as the Swan Nebula, Horseshoe Nebula, Lobster Nebula or with the catalog codes M 17 and NGC 6618) is an emission nebula, discovered by de Chéseaux in 1746 and rediscovered by Charles Messier in 1764, located in the constellation Sagittarius. Thanks to its luminosity, the Omega Nebula is quite easy to locate: it is located 2° southeast of the star γ Scuti. it can be identified quite easily even with 10x50 binoculars or even smaller, if the sky is dark and clear: in these instruments it appears as an elongated spot; through a 114 mm instrument, equipped with a UHC filter, it reveals a good part of its nuances and plays of light. From 200mm onwards the vision is exceptional, and it is advisable to take a long exposure photo to capture the rosy colour. Constellation: Sagittarius Right Ascension :18h 20m 26s Declination : -16° 10′ 36″ Distance : about 6000 a.l. Apparent magnitude: 6.0 This magnificent nebula was taken by my friend Gianni Lacroce. There are just under two hours of shots taken with a zwo ASI 2600 MC camera, a camera given to Gianni by a shopkeeper near Rome to test it. The owner had the doubt of a malfunction (later revealed not to be present). Talking about his performance, I asked him if I could elaborate these few shots and he kindly granted me the integration master.

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.
