The article focuses on the design and uses of next-generation extremely large telescopes (ELT). ELTs are optical telescopes with primary mirrors at least 98 feet or more in diameter. The mirrors for ELTs will be hexagonal segments which are lighter and save money in the construction of ...
Large aperture reflecting telescopes tend to be a favorite of astrophotographers for their light gathering ability. Astrophotography requires much dedication, but it can be incredibly rewarding to review and display your own work. Also, photographs can be used to gain scientific information about astron...

How do optical telescopes work? How does magnetism make an electric motor operate? How do cathode ray tubes work? How do holograms work? What is meant by a beam? How does gravity work? How can you explain work, in regards to electricity?
As you have been advised to do, slow down, find out how telescopes work, find out which are good buys, which are great buys, and learn how telescopes are affected by what they lean on, or against, how to aim them, what you can see from your location, what impediments and obstacles ...
How do refracting and reflecting telescopes work? How does the Hubble Telescope support the Big Bang Theory? How did Kepler's findings support the heliocentric theory? How powerful was Galileo's telescope? How do Kepler's laws relate to the Earth?

The etalons areprobably 1/100 of a wave accuratewhich is many, many times better than any of the telescopes. I think the longer focal ratio scopes might work the best with it. I've qualified a lot of etalons... large and small. 0.01λ peak-valley single pass wavefront (necessarilyinc...
