What does it mean - A stellar nursery when referring to any image taken by the Hubble Space Telescope?

snail asked:


is it possible to build your own telescope? the larger the mirror the more light it gathers what about focal length? some advertise for example 10 inch mirror with f 4.5 what does that mean?

Jin-Lamus asked:


I got a good budget of $1000 give or take realistically on the telescope, I want to see Planets, also would you know of any programs for Amateurs that will help you point your telescope and discover where in the skies do you find what you are looking for, I am fascinated and captivated by this, yet I am still a novice, any programs that might help or any sites, info that is useful! Thanks for the help!

Regina asked:


Two identical stars are moving in a circular orbit around one another, with an orbital separation of 5 AU (Sec. 2.6) The system lies 150 light-years from Earth. If we happen to view the orbit head-on, how large a telescope would we need to resolve the stars, assuming diffraction-limited optics at a wavelength of 2 µm?

I would like to view the horsehead nebula, along with lots of other things, but I am not sure what size telescope to get, I don’t want to spend a fortune though. Would a 4inch reflector do it or would I be better off with a refractor?

Peter asked:


Any autobiographies, letters, or diaries about discovering the 4 moons or something about the telescope would be great.

George N asked:


I have a computerized telescope that can be aligned and then automatically find objects. If I pick it up and put it somewhere else will it point in the wrong direction to find objects?

I like to use the telescope inside which is much more comfortable for me, and without opening the windows, it is clean glass windows. Would it see the stars and everything as well as taking astrophoto as good as it is outside?
