Astronomy meeting is behind the observatory






Affiliate of the NASA Night Sky Network 

APRIL 2018
The sun sets on Saturday, 14 April at 7:34 PM. We will meet at 8:00 PM at the Lewis Observatory.  
Dress for the weather. Lawn chairs are optional. If you have a telescope you wish to learn how to use or share, bring it to the meeting. Children must be accompanied by an adult.

It is fun to compare star colors through a telescope. We plan to look at brighter stars visible that evening. We’ll show you how to find them using constellations. We will observe nebulae, star clusters and/or galaxies as time permits. Venus will set at 10:06 PM.

If the meeting is cancelled due to weather, it will be posted here and on Facebook page


Bootes                          Arcturus  (reddish-orange; 3rd brightest star, cooler than our Sun)

Canis Major                  Sirius  (white to blue-white; brightest star)

Gemini                          Castor  (white to bluish-white stars and a few dim, red dwarfs; has 3-pairs of binaries revolving around a central point; 6-stars total!)

Gemini                          Pollux (yellow-orange giant)  

Orion                            Betelgeuse (called a red supergiant, it is orange-red)

Betelgeuse is a beautiful red star in our spring sky. You won't need binoculars to see the redness. It is 642.5 light years from Earth and the 10th brightest star in our night sky. It is 700-times bigger than our Sun.
Since it is in the constellation of Orion, it may be seen most nights of the year. When you look at Orion, Betelgeuse is the red star in the upper left corner.

APRIL METEOR SHOWER: LYRIDS on 22 April before dawn

Between April 16-25 the predawn skies will have 10-15 meteors per hour. This meteor shower is known for tantalizing surges which can have up to 100 per hour. Because of this, many people will rise a little early to check them out. The meteors will appear to come from the bright star Vega in the constellation Lyra. It will rise in the NE around 10:00 PM most April evenings. The peak viewing hours for 2018 are expected to be before dawn on Sunday, 22 April, when the Moon will not be visible.  See a short NASA video of a falling meteor at:

Black,Tabletop=Celestron-telescope-available-for-loanThe table top-Celestron telescope with clock drive, donated by club member Carl Matesich of Newark, may be borrowed for home use by club members for 1-2 months at a time. It will be on loan until May and available for another user at our May meeting.. If you wish to borrow that telescope in 2018 for a month or two, arrange to schedule the time with Irene ( ) That telescope is easy to carry and is supplied with a variety of lenses. When you see Carl, thank him for the donation. The telescope is pictured to the left.

The focus gear for the eyepiece on the Lewis Telescope has been damaged/stripped by use over the years. A new one is in the process of being made. Until then, we will use other telescopes, especially those brought by members. The 11-inch Celestron telescope donated by Dr. Hudnell Lewis should be available for our use beginning in April. Having been in storage, it is being transported to a designated area at the OUZ location.

If you see Mr. Todd Thacker, Director of Facilities Management & Campus Safety, thank him and his staff for their support to our organization. Since his arrival at OUZ, he has ensured our site is the darkest it has ever been during meetings and night sky observations. He has also provided safe storage for the Celestron telescope.Thanks also to the Leonard Hayhurst and the Zanesville Times Recorder staff for adding our monthly event in their newspaper. The NASA Night Sky Network and the Zanesville Astronomy Club appreciate the TR continued support in our community outreach efforts.  


Irene Baron and Chuck Bruckelmeyer will make a presentation at the John McIntire Public Library on 17 April 2018 beginning at 7 PM. The April presentation will be a hands on workshop about telescopes.


If you didn't get to see totality at the 21 August total solar eclipse, check out this NASA map for 8 April 2024. Most members of our club will live within 60-miles of totality!



Time will go fast, so plan way ahead to visit an eclipse area during the mid-day eclipse. The red line shows the area of the longest and greatest totality. If you are within the blue lines, you will see totality, but not as long of a time as you will within the red line. Cleveland will be the major eclipse city in Ohio. I imagine they will be making preparations for quite a while.

Meanwhile, plan way ahead for this. Arrange family time or time with friends to visit the nearest point you wish to visit that day.  Your current eclipse glasses will not be good at that eclipse as the material evidently can be used for only 3-years if it has no fingerprints or scratches. Mine aren't very pristine after this eclipse. The newer ones will most likely be better anyway.

I hope the NASA NIght Sky Network gives us free ones again.


Irene Baron and Chuck Bruckelmeyer of the Zanesville Astronomy Club made a presentation in Elson Hall at Ohio University Zanesville on 17 August 2017. If you were there, you saw it was standing room only with more waiting in the hallways.
uring the events leading up to the eclipse, 500-eclipse safety shades donated by Google & Berkeley University of California were distributed during the August club meeting and during the OUZ presentation..


During the presentation activities, persons signed in at the main desk, Many signed up to become a club member. They were from New Straitsville, Newark, Baltimore, Norwich, Quaker City, Glenford, Shawnee, Nashport, Frazeysburg, East Fultonham, Dresden, Adamsville, Minerva, New Concord, Roseville, Westerville and Zanesville. That geographic distribution shows how important Zanesville has become in astronomy family education.

Our club membership is currently 238. Not too bad after only 4-years of existence. 

We would like to thank the Muskingum County community and surrounding areas for their enthusiastic support of astronomy and the Lewis Observatory. To have Ohio University Zanesville support us and provide access to the observatory is deeply appreciated. Persons associated with the University have been active with working behind the scenes, including the facilities department who provides the Campus Center rooms for our use and turns off the lights surrounding the observatory. Thanks to our members who may not arrive for all meetings, but keep their interest.


Participants were introduced to the spring constellations and used the Lewis Telescope to view Jupiter's moons and atmospheric bands. To the left is the Trail Life USA-Troop OH 1722 members from Kennonsburg UM Church in Salesville, Ohio who joined us. It took them three cars and over an hour to drive to Zanesville. Members were from Quaker City and Senecaville, Ohio.

Plans are in the works to open the telescope more often for open viewing beginning about April 2017.

TELESCOPE AVAILABLE FOR MEMBERS:   We have a table top telescope members may borrow. If you have attended three meetings you may use it free for one month. Let coordinators Irene Baron or Chuck Bruckelmeyer know during one of our meetings if you are interested. Plan ahead for spring and summer viewing. Using it is great fun for all the family and friends.


June 2016 meeting: Two participants brought reflecting telescopes to share. We compared views through three telescopes of the Moon, Saturn, Jupiter and Mars. The Moon photo was taken by Irene through the Lewis Telescope using an iPhone4.

 Workshop: Identifying Conditions for Habitable Exoplanets - 9 January 2016
The Planet Hunting Workshop participants learned about citizen science, exoplanet detection methods, and learned how to determine whether an exoplanet can support life as we know it. 

Exoplanet-workshop-bookletThe materials for this first of many informative workshops about exoplanets were produced by the Adler Planetarium under a grant from NASA's Exoplanet Exploration Program at the Jet Propulsion Laboratory. The materials used during this workshop were supplied by the National Aeronautics and Space Administration.






 Boy Scout Workshop: In November 2015  there was an all day astronomy workshop conducted for local Boy Scouts wanting to earn their astronomy Badge. They were co-hosts as part of their Astronomy Badge that evening.






NASA Speaker Bryan Palaszewski made an evening presentation during the Ohio University Zanesville's "Third Thursday" community event on 15 October 2015 in Elson Hall at 7 pm.  Mr. Palaszewski made a presentation at Zanesville High School earlier that day. This NASA speaker was sponsored by the Zanesville Astronomy Club and Ohio University Zanesville.  MARK YOUR CALENDAR!NASA-SPEAKER-BRYAN-PALASZEWSKI Mr. Bryan Palaszewski has worked at the NASA Glenn Research Center at Lewis Field since 1989 and is currently directing research on high performance propellants and atmospheric entry. He currently conducts analyses for the NASA Office of the Chief Technologist investigating nanometer-scale propellant additives for metallized gelled fuels for many space mission applications. He recently led work related to human Mars entry, descent, and landing where supersonic retro-propulsion is planned for the final descent to the planet's surface. He is also investigating the mining of outer planet atmospheres and the challenges and benefits for future ambitious space missions. For 6-years he led many studies of advanced space systems for orbital and interplanetary travel at the Jet Propulsion Laboratory, Pasadena, CA. As the lead propulsion subsystem engineer on the Ocean Topography Experiment for 3-years, he was involved in other flight projects such as the Galileo Mission to Jupiter and the Cassini Mission to Saturn.


28 September 2015 Total Lunar Eclipse viewing at the Lewis Telescope

The total lunar eclipse was barely visible from Ohio on 27-8 September 2015. Totality lasted over an hour but didn't allow much clear sky for viewing. At OUZ we had less than a minute to see the Moon as a hole in the clouds passed in front of it. Those who showed up passed the time watching the NASA broadcast of the eclipse on electronic devices. There was much discussion by everyone about astronomy, so it was a fun time, even though we couldn't see the main event. Misting rain finally let us know the viewing was over a little after eleven. The Moon during that event is also called a "supermoon," and by the American Indians the "corn Moon" and/or "Harvest Moon."



Workshop September 2015- Telescope Construction presented by Chuck Bruckelmeyer

Participants from Nashport, Dresden, Philo and Zanesville created orbit scale models. They later viewed the Orion Nebula and Comet Lovejoy using the Lewis Telescope.

"Everything you want to know about the planet Jupiter but are afraid to ask" has been presented in addition to other planetary specialty events. An experiment was completed to demonstrate how varying sizes, angles and speeds of the meteorites create different types of formations. The objects impacting the material were dropped, thrown and propelled with a sling shot with immediate effects!

Amateur astronomer Chuck Brucklemeyer presented an informative program discussing how to grind and test a telescope mirror. He brought a mirror blank, a ground mirror, a Foucault tester and a spherometer. He proceeded to demonstrate how they worked. Participants were given the opportunity to use the Foucault tester in determining the accuracy of the ground mirror. He also let participants examine three of the numerous grits used in the grinding process. The 2-hour program was well received by those present. When asked if he would grind his own mirror, John Bowen who is owner of a Dobsonian telescope said, "Not at my age!" :-)





 During one past meeting after observing Mars, Jupiter and the gibbous Moon, solar spectroscopes, purchased from the Stanford University Solar Laboratory, were handed out to participants. Children at the event successfully made their spectroscopes with the provided materials. Images from the event are included below.

We were able to see Jupiter's swirling stripes and the four largest moons lined up in a row all on one side of the planet. Surprisingly, inside the observatory dome and out of the wind, the temperature was comfortable, even though outside it was below zero. Since winter skies are crisp and clear, the viewing was great. Irene cleared the sidewalk in front of the door of snow before anyone else arrived. Once Chuck arrived, he zeroed right in on Jupiter.

One of the discussions was the way modern telescopes were purchased with computers. If anything would happen to the computer, the user may not be familiar enough with the sky to find what they are looking for. Chuck had a set of over 100-index cards (3X5")created by another astronomer which gave information about all the Messier objects. The cards were printed with a diagram, location, etc. Chuck said there were several other sets of cards available for other objects. If an amateur astronomer had such cards, they would be able to locate objects in the sky easily when their telescope computer stopped working. He will discuss this issue of sky familiarization at a later meeting.

Below are included smartphone photos of the newly shoveled snow at the Lewis Observatory near sunset, and Chuck and John viewing Jupiter.

We are exploring options for an indoor meeting site during inclement weather since the university is locked and closed to our club on weekends. There may be an easy to find indoor site available to us. We will know once the Trustees of the site meet and hopefully approve of our using their facility. Keep your fingers crossed! :-)  


Winter meeting 14 December the university Subway Restaurant graciously let us meet and eat at their facility since the weather had deteriorated. Unfortunately, we're not allowed to meet inside the university as they are closed to weekend events. We had the Chandra X-Ray Observatory posters to distribute to participating members. Chuck Bruckelmeyer had his new telescope out for the first time. The telescope base was recently completed. What was impressive was his beautiful hand ground mirror. He stated he has mirror blanks to give away if anyone would like to try their hand at grinding a telescope mirror. See more photos at the Paparazzi link. Check out the group photo in the Paparazzi link!

The NASA Chandra X-Ray Observatory posters were absolutely beautiful. They were sincerely appreciated by everyone. Thank you NASA!

The Network provides information to the public such as local/state/national events, astronomy activities for ages pre-school through adult, videos, games and other astronomy resources.

The mission of the Zanesville Astronomy Club is to provide public outreach about astronomy. Monthly meetings are held at the Lewis Observatory located adjacent to the Rogge Pavilion on the Ohio University-Zanesville campus in Zanesville, Ohio.  The 17-inch Newtonian reflector telescope in the observatory is used for celestial observations. Club organizers Chuck Bruckelmeyer and Irene Baron invite community members of all ages to enjoy viewing the galaxies, stars, the Moon and planets. Baron said, “To have such a large telescope available for the community provides a unique resource for families and amateur astronomers. I would hope citizens will continue to take advantage of the free observational opportunities available.” Baron said she is available to open the observatory for school classes, scout troops and community/service organizations. She is also available as a public speaker to discuss past and current astronomy events, reminding that Comet ISON is arriving this winter.
