Description: Pretty bright planeteary nebula which is divided to two parts. W-part (NGC 2372) is brighter and it has a stellar nucleus but its not a central star which should be in the middle. I didn't see the c*, which is 12,5 mag. E-part (NGC 2371) is much fainter and larger than W-part. It has also a brigher nucleus surrounded with a fainter halo. Hourglass structure is clear and nebula minds me of M76. Pretty nice plantetary for these skies. I think OIII or UHC would help a lot.
