| Notes: |
These dark nebulae are two of several dark patches just North and East if IC 1396. B 170 is to the West of center (right), and B 171 to the East (left) of center. All three of the fields I imaged were taken mostly in heavy moonlight. See B 173 and B 174 taken during this moon period. First image presented as a reduced size option (1024 pixel width) |
