      Description

      Yerkes-McDonald-16 or RCW181
      I recently saw some images of this faint planetary in Serpens and thought it would make a good narrowband target while the moon is up.
      It is really faint at  Magnitude 14.4 and the moon didn´t help either, luckily the seeing was great, the worst frame was at 1.3"
      This is a plain Ha OIII bicolor and the OIII signal of the planetary is pretty weak although present.
      Hope you like it.
