Sh 2-255 and Sh 2-257
This image of 21x23arcmin, made from the DSS-colour with Aladin,
is centered on IRAS 06099+1800,
with the contour lines following the low-resolution IRAS 25µm image.
The three Sharpless HII regions, clearly visible in the red band, are, 
from left (East) to right (West):


IRAS 06099+1800 is therefore a blend between Sh 2-255 and Sh 2-257.
