This image is a Ha- RGB combine with Luminance layering. Color
saturation in LAB color; H-Alpha exposure stacks were used for the luminance
layer. Final Image size is approximately 2800 x 2100. North is up in this
image. In this image the Sharpless 235 is the small bright emission roughly
central in the image. The large dominating emission nebula toward the upper
right is Sharpless 232. in the visual center of this object is a small
planetary nebula G137.5+03.2 it is barely detectable in this image. Also in
Sharpless 232 toward its upper region is a dark nebula known as LDN 1523. Two
other emission nebulae are Sharpless 231 and 233. Sharpless 235 aslo have parts
A, B, and C trailing off just below. These emission nebulae also have LBN
designations. These
objects as well as some of the brighter stars are identified in the annotated
image. This image replaces an earlier image that can be seen in the Archives
