01/07/2016 – Ephemeris – The Orion entourage

January 7, 2016 Comments off

Ephemeris for Thursday, January 7th.  The Sun will rise at 8:19.  It’ll be up for 8 hours and 59 minutes, setting at 5:18.   The Moon, 2 days before new, will rise at 6:42 tomorrow morning.

The whole Orion entourage is now visible in the southeast at 9 p.m.  Orion the hunter with stars at his shoulders and knees and has a belt of three stars in a straight line.  He has one arm upraised holding a club from the reddish star Betelgeuse and in the other arm he’s holding a lion skin shield fending off an attack from Taurus the bull above and right of him.  Following the belt stars to the lower left we come to the brightest night-time star Sirius the Dog Star in the heart of Canis Major, his great hunting dog.  Making a nearly equilateral triangle with Sirius and Betelgeuse is Procyon the little dog star in Canis Minor, Orion’s other small hunting dog.  Hunched at the distracted Orion’s feet is the small constellation of Lepus the hare.

Times are for the Traverse City/Interlochen area of Michigan. They may be different for your location.

Orion photograph

Orion and the head of Taurus photograph by myself January 4, 2016 at 11:30 p.m. It’s a stack of 5 untracked 20 second exposures.

Limiting magnitude is about 8, so you’re seeing stars you’d see with binoculars.  The glow off to the left s from Traverse City, the center of which is 6 miles away to my northeast.  I’m looking south here to get out of the glow, so Orion is more upright.  I didn’t quite make it.  My southwest through northwest is the darkest.

As you can probably guess I’ve got a new camera for my birthday/Christmas, a Canon EOS Rebel T5, and I’m investigating its astrophotographic capabilities.  So expect some more “new” actual photographs on these posts.
