Urban Astrophotography 102

Zoom

Thursdays, 7 PM. Dec. 2, 9, 16; Jan. 6, 20, 27

Urban AP 102 teaches the use of Cooled CMOS Astrocameras and related software to electronically view and image Deep Sky targets. We emphasize techniques which make a wide range of Messier objects -- Galaxies, Nebulae, and Globular Clusters -- accessible even from light polluted Manhattan skies.  Our focus on dedicated astro-cameras and software like SharpCap and PixInsight is different from the DSLR oriented Night Sky Astrophotography Course.  We’ll show you how to use technology only widely available since 2015 – which has revolutionized backyard astrophotography -- to unlock distant night sky wonders even from the city.

Astronomy 102: Stars, Galaxies, Cosmos

Thursdays, 7 PM. Feb. 10, 17, 24; March 3, 10, 17

Astronomy 102 explores the universe beyond the Solar System. We discuss how and when the universe began, the formation of stars and galaxies, its expansion, and probable future. We study how astronomers measure great distances and how stars generate their tremendous energies. We will explore how elements are produced in stars, the structure and types of galaxies, and exotic objects like neutron stars and black holes.

CLOCKS, CALENDARS, COORDINATES, ORBITS

Wednesdays, 7 PM. March 30; April 6, 13, 27; May 4, 11

The measurements of time in hours, days, months, and years has astronomy roots. Historically, calendar dates were particularly complex to fix in all cultures because the Earth, moon, and sun have revolution rates that are not simple multiples. Objects in the sky and in space are assigned coordinates using different systems. These coordinates are vital to determining and specifying the motions and orbits of space objects. It takes six parameters to specify an orbit. We explore these themes.
