  1. Making a homemade telescope Astronomy is cool

  2. But first…

  3. What happens when black holes collide? • Most (or all) galaxies contain supermassive blasckholes • When two galaxies collide, blackholes • Directly collide • Spiral inward until they finally merge • Forces are so extreme that one of them is kicked away with tremendous velocity. The other receives energy, releasing a X ray flare lasting thousands of years • 100 collision have happened within 5 billion light years of Earth

  4. Lens configuration galileo

  5. Distance it takes for lens to bend light to a point

  6. Diameter is larger, magnification smaller, focal distance larger. • Therefore, smaller lenses would have smaller focal lengths and greater magnification.

  7. Magnification of telescope The smallest eyepieces can be 2-4.9mm, and they have small focal lengths and great magnification Good Refractor telescopes are LONG

  8. 20-50 X = wide field views of extended deep sky • 20- 100 X=deep sky observing (galaxies) • 75-200 X = Moon, planets compact objects (globular clusters)

  9. Longest refractor telescope

  10. Is magnification all that good? • When using high magnification (lower focal length) you’re only spreading the same lgiht over a larger area. • You’ll get a blurry, dim image

  11. Grinding the mirror

  12. Creating parts
