With Shuttle launches averaging $500 million each and this last Hubble repair mission coming in at $1.1 billion. Could we have had a new modern space telescope for the money we spent on the 5 repair missions?

:3 asked:
A telescope with a 20 cm primary mirror has an f# of 5. What would be the focal length of the eyepiece required to give a magnification of 100? I know there’s an equation, but I don’t know what it is. Thanks in advance.

Rhys asked:
I was just wonder what type of telescope would be best. I know that £100 is not going to buy a great telescope but I can’t afford any more at the moment. Thanks

Aquamarine Blue Beauty asked:
Compare the function of the objective lens of a telescope with the objective of a microscope. In each case, do you want a large focal length or small? Why? Where is your object? Where and what kind of image is formed? Compare the function of the eyepiece in both instruments. Do you want a large focal length or small? Why? Where is your ‘object’? Where and what kind of image is formed?

astrologus491 asked:
I have this cheap telescope that I want to manipulate to increase it’s field of view/decrease magnification for an electronic eyepiece. Is there something I can do with the primary mirror? Do companies make the reverse of barlow lenses?
