The September 2019 meeting of the Cuyahoga Astronomical Association (CAA) will feature a presentation by Dr. Stacy McGaugh, Case Western University Professor and Chair of Astronomy. In “Dark Matter and Gravity in the Universe,” Dr. McGaugh will discuss his work on the search for dark matter and the possibility that it does not exist and we simply do not understand gravity! He has co-authored several papers outlining this controversial view.
The CAA’s monthly meetings are held on the second Monday of every month except December at 7:30 p.m. in the Rocky River Nature Center; 24000 Valley Parkway; North Olmsted, Ohio, in the Cleveland Metroparks. Meeting programs are open to the public. Following the presentation and a brief social break, the club will conduct its membership business meeting.
A nighttime visit to Lake Erie’s Marblehead Lighthouse provided the perfect opportunity for the Cuyahoga Astronomical Association’s Alan Studt to create this beautiful image. This nightscape isn’t a simple, single-exposure image as done in the old film camera days.
Here’s what went into making this picture:
Shot an approx. 22-minute star trail between 11:30 and Midnight (100 – 13 second shots at ISO 3200).
Edit out dozens of airplanes – probably all but a handful of the shots had multiple planes flying by.
Foreground is made of 45 images median stacked equaling about a nine-minute exposure.
Tamron 15-30mm @ 15mm, f /2.8

“Beautiful evening!” says Studt. We agree, and thanks for sharing!
The Cuyahoga Astronomical Association (CAA) was well-represented this year at the annual Lakewood Solstice Celebration held on the shores of Lake Erie. CAA members brought 11 telescopes to help support a successful annual Summer Solstice program at Lakewood City Park.
Lakewood Park features an amphitheater-like Solstice Steps facility where visitors are able to view the Great Lake. The evening event draws thousands and boasts food, music, activities and, thanks to the CAA, safe solar viewing and after-sunset astronomy.
Attendees enjoyed clear, sunny skies for most of the day right up until just before sunset. Safe solar viewing was offered through a variety of telescopes and filters though, because Sun was at Solar Minimum, there wasn’t much to see on old Sol’s face.
A group of clouds moved across the Lake Erie horizon from the northwest covering the Sun and obscuring Mars and Mercury, which also should have been visible at sunset.
After sunset, however, Jupiter rose above the trees in the east, providing an opportunity to show visitors Jupiter and a few of his Galilean Moons.
CAA member Jay Reynolds again organized and coordinated the Solstice astronomy program with the city of Lakewood. Reynolds passed along compliments from the city for the timely and organized manner in which members arrived, unloaded, and kept the flow going as members set up their telescope systems.
Lakewood city officials and staff welcomed and supported CAA as part of their annual event. Lakewood Mayor Mike Summers and his wife, expressed how much they enjoy coming to the event and this (telescopes) was their favorite part!
The Lakewood Solstice Celebration is one of several public events in which CAA members provide astronomy outreach programming. “It’s what we do.”
This report by CAA President William Murmann and others.
Come see deep-sky objects, planets, and the Moon up close using the Cuyahoga Astronomical Association’s (CAA) telescopes, from 9:00 to 11:00 PM, Saturday, June 8.
The CAA Observatory will be open for public viewing, and members will be available to answer your questions. Activities and/or displays will be set up inside the barn for further interest on cloudy nights. Given clear enough skies, visitors may view Earth’s Moon, planet Jupiter, and star clusters through a variety of member-owned telescopes.
This is an outdoor program so attendees should dress appropriately for conditions; use of insect repellent is also recommended.
