Lagoon Nebula _ Messier 8

The Lagoon Nebula, Messier 8, NGC 6523, is a giant interstellar cloud in the constellation Sagittarius. It is classified as an emission nebula and as an H II region.

The Lagoon Nebula was discovered by Giovanni Hodierna before 1654 and is one of only two star-forming nebulae faintly visible to the eye from mid-northern latitudes. Seen with binoculars, it appears as a distinct oval cloudlike patch with a definite core. Within the nebula is the open cluster NGC 6530.

This was one of three of the first light images that was taken with the Mewlon250CRS and ZWO ASI094

Die sehnsucht nach sternklarer Himmel ist gross, leider ist es schon sein einigen Monaten immer bewölkt, obwolh es kleine lücken gibt die aber nicht lang genug sind das man sich richtig Installieren kann.

Der Lagunennebel, Messier 8, NGC 6523, ist eine riesige interstellare Wolke im Sternbild Schütze. Es wird als Emissionsnebel und als H II -Region klassifiziert.

Der Lagunennebel wurde vor 1654 von Giovanni Hodierna entdeckt und ist einer von nur zwei sternbildenden Nebeln, die aus den mittleren nördlichen Breiten für das Auge schwach sichtbar sind. Mit einem Fernglas betrachtet erscheint es als ein deutlicher ovaler wolkenartiger Fleck mit einem bestimmten Kern. Innerhalb des Nebels befindet sich der offene Cluster NGC 6530.

Dies war eines von drei der ersten Lichtbilder, die mit dem Mewlon250CRS und dem ZWO ASI094 aufgenommen wurden.

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.
