Here we go again, two versions, first for Parallel Vision and
second for Cross Vision method.

Image info in the original Sh2-157 post.
From Sharpless Catalog, Sh2-142
Last night, after long cloudy period, there was three hours opening
in the clouds, so I continued the Sharpless catalog object hunting.
I managed to shot H-alpha channel for Sh2-142 object, seen
in midle of image, hence B&W version.
I'll shoot S-II and O-III channels, when weather up here allows.
-
I made a small mosaic with the previous targets H-alpha
channel to show Sh2-142 and Sh2-157 relative positions to each other.
