06/04/2021 – Ephemeris – Zoom astronomy meeting and possible star party tonight

June 4, 2021 Comments off

This is Ephemeris for Friday, June 4th. Today the Sun will be up for 15 hours and 25 minutes, setting at 9:23, and it will rise tomorrow at 5:58. The Moon, 2 days past last quarter, will rise at 3:49 tomorrow morning.

The Grand Traverse Astronomical Society hold a virtual meeting and program at 8 pm tonight via Zoom. For the program Jerry Dobek, professor of astronomy at Northwestern Michigan College will present an illustrated talk on astroimaging. The pandemic has inspired Dr. Dobek to find a solution. It turned out to be a relatively inexpensive imager for the telescope. The virtual star party will start around 9 pm, hosted by Dobek, with his imager, but only if it’s clear in Traverse City. It will feature a look at Venus to start, possibly before sunset. There will be other objects visible in the twilight such as binary stars and a pair with differing colors. Instructions to join the meeting and a link can be found on the society’s website,

The astronomical event times given are for the Traverse City/Interlochen area of Michigan. They may be different for your location.


Here are some images that Professor Dobek has produced during the GTAS virtual Zoom star parties that I screen captured and minimally enhanced:

M46 with planetary nebula

The planetary nebula that is probably within star cluster M 46 in the constellation Puppis. Created from a screen grab from an image by Jerry Dobek January 8, 2021 during the GTAS virtual star party. The image was enhanced to reduce the background and increase contrast by Bob Moler

Globular Star Cluster M 3.

Irregular galaxy M 82 is very strange. Image created by Jerry Dobek and enhanced using GIMP.

01/04/2019 – Ephemeris – A talk about astrophotography tonight at the GTAS by Dan Dall’olmo

Ephemeris for Friday, January 4th. The Sun will rise at 8:20. It’ll be up for 8 hours and 55 minutes, setting at 5:15. The Moon, 1 day before new, will rise at 7:55 tomorrow morning.

Tonight’s first meeting of the year of the Grand Traverse Astronomical Society at Northwestern Michigan College’s Rogers Observatory starting at 8 p.m. will feature an illustrated talk by Dan Dall’olmo who has been quite successful in the field of astrophotography, or photography of the heavens. My own introduction to astrophotography was as a teenager in the day of file and darkroom chemicals. Things have changed a lot since then. Starting at 9 p.m. if it’s clear there will be a star party featuring the dark winter sky wonders including the Great Orion Nebula, a star nursery. Our next meeting, February first will be our annual telescope clinic to help new and otherwise frustrated telescope owners understand and use their telescopes.

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