Sharpen up your telescopic Views with Atmospheric Dispersion Correction!

At the October 8, 2022 meeting of the Columbus Astronomical Society, secretary Don Leonard shares technologies to sharpen up your views of planets and the Moon with Atmospheric dispersion correction, something that cannot be done without special optics.
The Columbus Astronomical Society meets on the second Saturday of every month, usually at Perkins Observatory at 8:00 PM. All are welcome to attend and learn about astronomy.
