The Cocoon Nebula and Clusters
IC 5146 Cocoon Nebula and Clusters (Draco62 RMod).jpg
This is a wide-field framing of the dusty region of sky in northern Cygnus containing the small magenta and blue Cocoon Nebula, aka IC 5146, at centre, which appears at the end of a long dark nebula catalogued as Barnard 168, but sometimes called the Cigar Nebula. But the entire field is permeated with yellow-brown dust, as well as diffuse red emission nebulosity, contrasting with the bluer dust-free regions of the Milky Way.
Two open star clusters flank the Cocoon/B168 complex:
-- at lower left is the sparse and large NGC 7209 in Lacerta,
-- while at upper right is the bright and large Messier 39 open cluster, in Cygnus
The yellow star at lower right is Rho Cygni. The blue star at top is Pi2 Cygni.
The field is 8. 2º by 5.5º .
Technical:
This is a stack of 30 x 3-minute exposures with the Founder Optics Draco 62 astrographic refractor at f/4 with its Reducer/Flattener, and the red-sensitive astro-modified Canon R camera at ISO 800. No filter was used here.
The scope was on the Star Adventurer GTi equatorial mount autoguided with the ASIAir and ZWO guidescope. Taken from the Quailway Cottage in southeastern Arizona in October 2024.
