Do you have binoculars? How about a quick science lesson?
Go here for more astronomy lessons: www.SuperchargedScience.com/stars
There are two types of binoculars:
- ROOF PRISM are more compact and more expensive and make slightly dimmer images.
- PORRO PRISM have a zigzag shape and are heavier and bulkier, but better for astronomy.
To focus your binoculars:
- Use central knob to focus the eyepiece that can’t be adjusted, and then focus the other eyepiece.
Example: If you have a pair that are 7 x 50:
- As magnification increases (the first number), object in your viewing area becomes bigger. For astronomy, get at least a 7.
- As the objective lens size (second number) gets bigger, more light gets in but the binoculars get bigger and heavier. Get at least a 35, if not 50.
- To use them for astronomy, remember to use low power, like 7×50 or 10×50.
- Lean against something if you are standing, like a car or a tree to steady yourself. (Use a lawn chair if you are sitting.)
- Use a simple mount with an L bracket if you find you can’t hold them steady enough.
Here’s the original Facebook Live video I created that demonstrates this and more:
