Description:
Interestingly IC 2003 looks brighter than its neighbor IC 351 which has a
catalogued brightness of 12,0magv and should therefore be half a magnitude
brighter than IC 2003! At 342x the PN shows a 7" disk that is brighter in the
center. No central star seen. I did not see any color either.
