This cascade of stars shrouded in smoky wisps of nebulosity caught my attention as I made the star hop from Gamma Cygni to IC 1318(b). The cascade ends at the sparse open cluster Collinder 419, whose brightest star is a close pair known as Struve 2666 (6.0, 8.2; 2.6"; 245°). Just northeast of this cluster the narrow stream of nebulosity blossoms into a hazy morass of delicate nebulosity – this is IC 1318(c). Fifth magnitude HD 193092 blazes with a reddish-orange light to the south.


Sketch Info: Nebulosity sketched with graphite applied with artist chamois and blending stump on 24# paper in 7˝" circle. Stars with pencil and ink, cleaned up digitally (and colorized) in Microsoft Picture It!
