Telescope on polluted environment this one bothering me,to buy a telescope.
I live in a city,unfortunately with dust and polluted air, is there any affect in viewing a nice capture of our galaxy? Or i need to buy a special telescope?
If you are going to buy a telescope in the city let me suggest a large aperture and a reflective telescope.  I live in a city as well and I use a reflector telescope.  I did have trouble with some dimmer galaxies to start with but if you buy a light pollution filter you can see them a lot better.  Also take a series of images of the same object and then stack them together!  There are many free astronomy image stacking programs on the web.

Have fun!
