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,
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
