Introduction to Astro Imaging

September 21 @ 7:00 pm - 8:30 pm

Given that one can download finished images from JPL, why do amateur astronomers build complex imaging systems? It is very fulfilling to process color images of galaxies and nebulae even in Santa Clara Valley skies. Speaker(s): Francesco Meschia, Agenda: Here is a preliminary outline of the topics that will be covered: Brief introduction to Astronomy – viewing the galaxy from a place on the earth stars appear to rotate the equatorial coordinate system to compensate for this The birth of astrophysics spectral signatures spectral lines – what are they historical observations modern explanations implications of which places might have earthlike elements that are needed for life. Stellar Evolution Why narrowband imaging instead of RGB? narrowband filters vs RGB What kinds of imaging sensors to use Where do you need to go to see very distant deep space objects? Cutting through city lights with a combination of narrowband filters, notch filters for sodium, and averaging hundreds of images over several hours. Selectivity, Contrast, and Detail The entire concept is the same as Signal to Noise ratio in communications How to guide the telescope to track it precisely over several hours How to capture the image data filters and exposures Brief Introduction to image processing Virtual: https://events.vtools.ieee.org/m/322506
