Sh 2-192, Sh 2-193, and Sh 2-194 form a small nebular group near the Heart and Soul complex of star formation regions.
Sh 2-192 appears as a classic Stromgren sphere. The others are irregular nebular patches. Avedisova places all three in the star formation region SFR 136.09+2.10
Russeil concludes that Sh 2-192, Sh 2-193 and possibly Sh 2-196 (but not Sh 2-194) are part of the same star formation region.

Sh 2-192, Sh 2-193 and Sh 2-194 are all near the W4 and W5 complexes. [2
