The monthly general membership meeting of the Cuyahoga Astronomical Association will take place March 9, 2020 from 7:30 to 9:00 p.m. CAA Member and Vice President Tim Campbell will present his talk, “Mauna Kea: Telescopes above the Clouds!” — his visit to Hawaii’s Mauna Kea mountaintop observatories (MKO). Several major telescopes are located there at 14,000 feet above sea level. Mauna Kea is one of the most important sites in Earth-based astronomy and Campbell will take attendees on a detailed tour!

The CAA’s monthly meetings are held on the second Monday of every month except December at 7:30 p.m. in the Cleveland Metroparks’ Rocky River Nature Center; 24000 Valley Parkway; North Olmsted, Ohio. Meeting programs are open to the public. Following the presentation and a brief social break, the club will conduct its membership business meeting.

Beautiful M42 in crystalline skies

Orion Nebula, M42, by Hayden Gill. February 2020

Hayden Gill, a member of our Cuyahoga Astronomical Association (CAA) braved a very cold but crystal-clear February night collecting image data to create this picture; it was also his very successful first effort at image stacking.

Gill wrote: “I shot it with a Nikon D7200 on a SkyWatcher EvoStar 80ED {telescope}, CGEM II mount. For guiding I have a 60mm ZWO scope and a ZWO 174 mono” guide camera. He used his Nikon for the data capture and Deep Sky Stacker to build the image. Each exposure was two minutes at ISO 800. He used 34 light images, 20 darks, 20 flats, 25 bias frames. Post processing was in Photoshop.

“This was my first attempt at astrophotography stacking. First time stacking and first time really putting all my gear to use how I have been intending to. Can’t wait to get back out!”

We will be eager to see Gill’s continued progress and images!

On Monday, February 10, at 7:30 p.m. the Cuyahoga Astronomical Association (CAA) will conduct its monthly club meeting. The meeting will feature a talk by CAA member Kai Getrost, a member of the special NASA teams that performed occultation studies in support of NASA’s New Horizon’s space probe to “Ultima Thule.” He is currently working in support of NASA’s Lucy Mission to explore Jupiter’s Trojan Asteroids. The Lucy spacecraft will launch in October 2021 and, with boosts from Earth’s gravity, will complete a 12-year journey to seven different asteroids.

As part of the NASA science teams in support of the New Horizons and Lucy Missions, Getrost has traveled to South America and to Australia to help gather occultation data used to help guide the spacecraft.

The CAA’s monthly meetings are held on the second Monday of every month except December at 7:30 p.m. in the Cleveland Metroparks’ Rocky River Nature Center; 24000 Valley Parkway; North Olmsted, Ohio. Meeting programs are open to the public. Following the presentation and a brief social break, the club will conduct its membership business meeting.
