Here’s your chance to find Neptune – tonight only

Mars and Neptune

Mars and Neptune tonight only. Here is where Cartes du Ceil (Sky Charts) puts them at 7 p.m. January 19, 2015. They will be low in the southwest. Mars is second magnitude, Neptune is 8th.

The outer red circle matches that of the popular Telrad telescope finder and is a bit smaller (4º) than 7 or 10 power binoculars.  The smaller circle is a 2° circle.  It will take binoculars at least and a clear sky to spot this outermost planet.

Galileo actually recorded Neptune with his primitive telescope when Jupiter passed it.  But to Galileo it was simply a background star.

Note:  The 7 p.m. time in the caption is local to western lower Michigan.  My location is 43 minutes behind Eastern Standard Time.  If you are near your time meridian the time is more likely 6:15 p.m.  This normally isn’t a big deal, but These planets are close to setting.
