Comet, Galaxies, and IFN Nebula

Comet C/2017 T2 PanSTARRS, dragging two long and straight dust tails, passed by near the galaxies M81 and M82.

In this long-exposure photo, some nebulae can also be seen filling the entire field of view. They are Integrated Flux Nebula. Unlike ordinary nebulae illuminated by nearby stars, IFN is far away from the Galaxy disk and is illuminated by the stars in the entire galaxy.
