Phantom asked: Can you see the surface of a star from using the telescope u buy from the shop?
Just the ordinary one, because I want to buy one.
Like how detailed and how far can you see from using the telescope?
Thank you very much.

manoftrust72 asked: I’m looking for a telescope where portability matters alot, and I want the clearest astro photograph where all the stars appear very sharp like points, and I would like to find some giant exoplanets. Which telescope is best for astrophotograph and for the money? Cassegrain, Reflector or Refractor?

raul asked: diameter of 8mm, how many photons per second could newton detect with the telescope compared to without? 8? 17? 33? 38? 1089? I believe it is 1089 i sqaured the diameter of each and subtracted
Assuming 100% reflectivity of the mirror and he used only one eye

raul asked: of 8mm, how many photons per second could newton detect with the telescope compared to without? Assume 100% reflectivity of the mirror and that he just used one eye. I squared 33 and 8 and subtracted them from each other. The choices are 8, 17, 33, 38, 1089. I believe it is 1089. Any confirmation?

shish2kabob asked: I have an Orion Skyquest XT8 Dobsonian telescope :
http://eridanusoptics.com/store/images//telescopes/dobsonians/OR9707.jpg
i have heard using a hair dryer works but i do not think it will reach down the optical tube down to the mirror. i also don’t have a portable one. will putting plastic wrap over the front of the tube work to reduce the dew? will it affect the image that i see?

Altair asked: I have seen wesites on how to build your own dobsonian telescope. I know that the primary mirrors of most dobsonian telescopes have a focal length ranging from 1000mm to 1200mm. But I do not know whether my hand mirror fits into this catagory. I don’t mind having a telescope with a small aperture.

john asked: I got a telescope for Christmas and was wondering if there are any good sites near Perth, where I can the avoid the light pollution to get a good clear view of the sky preferably something easily accessible, as I don’t fancy carrying the telescope to the top of a mountain.
