Open to Public. Astroschool at 6:15PM. Jim Johson hosts this meeting. His topic is: "Gravity, I'm not Half the Mass I Used To Be". General Meeting starts at 7PM. Guest Speaker: HAL's own Gary Friskhorn, award winning personal telescope maker. His talk will be preceded by the 2020 Board of Director Elections and the Annual Treasurer's Report (both very short).
HAL member Gary Frishkorn, now retired, last worked for the Johns Hopkins University Applied Physics Laboratory as a Software / Systems Engineer. About 30 years ago he became very interested in amateur telescope making. His first project was the design and construction of an 8-inch Newtonian telescope, including grinding and polishing of the primary mirror. His current project is a 4.5 inch, f/16 refractor telescope. The design of its achromatic objective is now complete and polishing of its elements underway.
This talk will describe his 6-inch aperture binocular telescope and chair mounting. In 2006, it won first place awards at Stellafane for the mechanical design, craftsmanship, and compound optical performance categories. The key features of the telescope's conception and design will be covered, followed by a demonstration of its setup and use.
Open to Public. Doors open at 6PM. Astroschool at 6:15PM. Jim Johnson's topic for Astroschool is: "Gravity: I'm Not Half the Mass I used to Be (Part II)".
General Meeting starts at 7PM. Guest Speaker Marty Cohen of Company 7 will be leading a discussion on the different types of telescopes, what makes them different from each other, and things you should consider when choosing the telescope style that you will get the most enjoyment when using. This is guaranteed to be a lively interactive session that many of you are very excited about. To help with the discussion, if you can bring a small refractor, dobsonian, SCT or other type of easy to bring in and take out telescope, please send an email directly to Victor Sanchez at firstname.lastname@example.org.
New Vice President Victor Sanchez will run the Meeting. He will be talking about; "I gotta find some darker skies". It will be very interesting. Victor is not only our HAL VP, but an accomplished amateur astronomer and imager.
