TWC Observatory and the

Dr. Karl W. Keller Telescope


Keller II Telescope

Giust Telescope 

Giust Telescope,
                              Astrophysics 6’ f/8 apochromatic
The Giust Telescope is an Astrophysics 6’ f/8 apochromatic refractor. It was donated to TWC in 1985 by the late Norman Giust of Canton in memory of his parents and nieces.  Mr. Giust had an armchair interest in astronomy, and he wanted to make a gift to a local organization that could use the telescope to show folks the sky.  He bought the telescope new, and it arrived in November, 1985, just in time for Halley’s Comet.  It was a standalone telescope on an outdoor pier until the AEB was completed.  At that time, the telescope was disassembled, powder coated at Powder Innovations, then reassembled and shipped back to Astrophysics for collimation and cleaning of the optics.  We designed a cradle to mount it on the Keller scope (as shown in the Keller photo on the top right), or it can be used as a separate instrument on its own mount and tripod as shown above.

Resetar Telescope

                              telescope, Meade 10 in. LX200
We were pleased to accept a new telescope on behalf of The Wilderness Center in 2001.  The Philip Janecko family of Jackson Township donated the instrument in memory of Mrs.Janecko’s late brother, Bill Resetar, who owned the telescope. Mr. Resetar lived in the Youngstown area.  The Resetar Telescope is a 10” Meade LX-200 Schmidt-Cassegrain with many eyepieces.  TWC was chosen as the home for this fine instrument because the Janeckos believe that we are in a position to immediately incorporate it as an integral part of our education program. It resides in the observing chamber of the Astronomy Education Building, and is not a loaner telescope.  We are grateful to the Janeckos for their generosity.

Dr. Pleshinger Telescope

Dr. Pleshinger
                              scope, Meade 10 in. LX200
Dr. Pleshinger from Dover donated a 10 inch Meade LX-200 Schmidt-Cassegrain with an equatorial wedge and accessories. It is another part of our astronomy education programs at the observatory or at outreach programs. It is kept in the Astronomy Education Building and is not a loaner telescope. We are grateful to Dr. Pleshinger for his generous donation.

Solar filters

Daytime observing activities are usually limited to the brightest star in our sky, the Sun.  Observing the Sun must only be done with special filters that safely block the harmful radiation and heat that is concentrated by a telescope or other optical device.  We use two filters that allow us to observe the sun safely.  First, the Baader Astro-Solar white light filter provides nice sharp views of the photosphere where we can observe sunspots as they cross the solar disk.  The second device is a Coronado Instruments Hydrogen-Alpha filter.  The H-Alpha filter transmits a very narrow slice of the visible spectrum (0.8 angstrom) centered on the bright hydrogen-alpha line at 656.3 nanometers, providing views of the chromosphere.  Here we see many interesting features including streams of matter called prominences, looping out  then  streaming back to the Sun, long dark filaments of cool gas, and granulation that shows the dynamic activity of the sun.
