Description:
138X - NGC6857 appears as a small faintly glowing patch surrounding a star located a little to the west of the center of the nebula. The nebula appears elongated E-W, uniformly diffuse. Easy with direct vision even though the surface brightness is low. SH2-100 overlapping and mostly to the W of NGC6857 was not detected. Note the interesting trifed asterism 3.2' almost due S.
254X - NGC6857 appears much the same as with 138X. No other DSO's detected in the FOV.
