IC5146 (Caldwell 19, Sh 2-125, nebulosa Bozzolo) è un ammasso aperto associato ad una nebulosa diffusa molto piccola a forma di Bozzolo nella costellazione del Cigno che dista circa 3300 a.l. A sua volta è connessa ad un sistema di nebulose oscure catalogato con la sigla B168 e reso visibile perchè oscura un fitto campo stellare.

Non pensavo che questo oggetto DS fosse così ostico. Malgrado un'integrazione di 3h 35min la profondità raggiunta non mi ha molto soddisfatto. Io penso che le condizioni ambientali abbiano influito negativamente, ma ho comunque voluto condividere il risultato raggiunto con il mio setup.

IC5146 (Caldwell 19, Sh 2-125, Cocoon Nebula) is an open cluster associated with a very small diffuse nebula shaped like a cocoon in the constellation Cygnus, which is about 3300 ly. This in turn is connected to an obscure system of nebulae cataloged by the initials B168 and made visible because obscures a dense star field.

I did not think that this DS object was so difficult. Despite integration of 3h 35min depth reached has not me very satisfied. I think that the ambient conditions have a negative impact, but I still wanted to share the achievement with my setup.

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.
