Description

SH 2-157 The Lobster Claw

First time with this object which proved to be somewhat of a challenge to process. The nebula is faint with a background saturated with fainter nebulosity everywhere. Numerous color channels were tried without satisfaction until a HOS combination seemed to work best. PixInsight Curves was applied several times until a final "lobster" type appearance was obtained. Since there are only two pages of this object available, others may have experienced the same issues.
