Ephemeris: 01/03/2025 – GTAS Telescope Clinic tonight

January 3, 2025

This is Ephemeris for Friday, January 3rd. The Sun will rise at 8:20. It’ll be up for 8 hours and 55 minutes, setting at 5:15. The Moon, 3 days before first quarter, will set at 9:37 this evening.

Did you or someone in your family get a telescope for Christmas, or have one in a closet or attic because you don’t know how to put it together or how to operate it? Or maybe you are trying to figure out which one to buy. Well, tonight’s your night. The Grand Traverse Astronomical Society (GTAS) will host the annual Telescope Clinic starting at 8 pm at Northwestern Michigan College’s Rogers Observatory. Professor Jerry Dobek will demonstrate the types of telescopes and how to use them. He and other members may be able to help particular problems by seeing participants telescopes, so “bring ‘em if you’ve got ‘em.” This is interesting to say the least. Go to gtastro.org for information and a Zoom link for the meeting.

The astronomical event times given are for the Traverse City/Interlochen area of Michigan (EST, UT – 5 hours). Times will be different for other locations.

Addendum

Telescope types
The three basic telescope tapes: Refractors use lenses to form the image, reflector telescopes use mirrors, and catadioptric telescopes use both. The three types are shown with the path of the light takes through them to the eyepiece.
