NGC 6914 is a reflection nebula embedded within the diffuse emission
nebulosity of the Cygnus region. The region represents an immense
collection of young stars, most of which are hidden by surrounding
dust. The blue reflection nebula to the right is known as NGC
6914A (vdB 131), and the one on the left is NGC 6914B (vdB 32). I
found this to be a difficult region to image with an 8" scope- it is a
relatively faint area, and the detail within the reflection nebula is
difficult to resolve at this aperture and image scale (1.14 "/pixel),
especially given the typical seeing at my imaging site (around
3"). Here is what is achievable with a 20" aperture
scope, and here is what can be captured with a 24"
aperture scope, both obtained a dark sites with good seeing.
