Ic5146 And Barnard168

Εν όψει της επερχόμενης εξόρμησης στον Πάρνωνα, έφτιαξα άλλη μια από τον Αύγουστο... η περιοχή έχει πολύ ενδιαφέρον, έχει απ' 'ολα γενικά - φωτεινά, σκοτεινά, αμυδρά και αυτό το ασύλληπτο αστρικό πεδίο. Σκέτη απόλαυση στην επεξεργασία! Ελπίζω να σας αρέσει

Description:

IC 5146 (also Caldwell 19, Sh 2-125, and the Cocoon Nebula) is a reflection/emission nebula and Caldwell object in the constellation Cygnus. IC 5146 refers specifically to the nebula and Collinder 470 to the star cluster. It is located near the naked-eye star Pi Cygni, the open cluster NGC 7209 in Lacerta, and the bright open cluster M39. The cluster is about 4,000 ly away, and the central star that lights it formed about 100,000 years ago the nebula is about 12 arcmins across, which is equivalent to a span of 15 light years. When viewing IC 5146, dark nebula Barnard 168 (B168) is an inseparable part of the experience, forming a dark lane that surrounds the cluster and projects westward forming the appearance of a trail behind the Cocoon.
