Preview: Comet 45P/Honda–Mrkos–Pajdušáková Brightens in December

And Comet 45/P is just one of the fine binocular comets on deck for 2017. We're also expecting Comet 41P/Tuttle-Giacobini-Kresák, 2/P Encke, C/2015 ER61 PanSTARRS Comet C/2015 V2 Johnson to break +10th magnitude next year... and the next great naked eye 'Comet of the Century' could light up the skies at any time.

Binoculars are the best tool to observe bright comets, as they allow you to simply sweep the star field and admire the full beauty of a comet, coma, tail(s) and all. Keep in mind, a comet will often appear visually fainter than its quoted brightness... this is because, like nebulae, that intrinsic magnitude is 'smeared out' over an extended area. To my eye, a binocular comet often looks like a fuzzy, unresolved globular cluster that stubbornly refuses to snap into focus.

Don't miss your first looks at Comet 45/P 45P/Honda-Mrkos-Pajdušáková, as it spans 2016 into 2017.
