Description

Comet C/2017 O1 ASASSN, down left, is observable by binoculars now while approaching to perihelion showing a greenish coma of diatomic carbon and a small ionic tail. At same time comet C/2015 ER61 PANSTARRS, up right, moving away since four months ago and twice as far from Earth, can be still imaged with a long and narrow tail. Between both is glimpsed a shred of IFN (Integrated Flux Nebula) very near to Pleiades located next to field toward the top right.
