Telescope Buying Guide

AnnaKarenina asked:


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

Nick G asked:


Suppose that you have 2 telescopes with the same aperture, Telescope A has a focal length 3 times longer than that of telelscope B. How would the image size differ in telescope A from that in telescope B?

Mathuroindia asked:


I want a telescope that can view objects in deepspace clearly, and is not too pricey. I am a beginner at stargazing but I know a lot about what is out there. But I just wanna see em too instead of just googling the images. Got any tips, and telescope models? I am open to anything.
Ok really nice post B, I will certainly check out Orions telescopes.. My dad is really into astrology so he can help me with finding stars and the such.

naruto asked:


Thanks to all of you guys who answer my first question.. I really don’t know about telescopes, this is my first one. Also the telescope has like a circle with lots of numbers and I thought they were you know to see the figure closer but I didn’t really get them closer.. They still pretty far.. So how do I see the images bigger? For example the stars.

MCJEduardo asked:


Many things have been said about that men actually never got to the moon. With current technology, is it possible to point a telescope to the moon to those places where it is supposed man walked? Has this been done in the past? Are there any images out there? If not, with what kind of telescope would it be possible?

a)It is the best angular resolution the telescope could achieve with perfect optical quality and in the absence of atmospheric distortion.
b)It is the maximum size to which any telescope can be built.
c)It describes the maximum exposure time for images captured with the telescope.
d)It describes the farthest distance to which the telescope can see.
