TELESCOPE Please help I am a first time buyer.which one of following is best?

I am a beginner and buying a telescope for first time and I want a telescope which can give mea crisp and clear images of distant planets like mars and some nabulaes.I searched for astro clubs/societies but there is not a single one in my town!then searched over internet and found the three telescopes .I want expert comments to buy from following telescopes first two are startracker (INDIAN) and last one is Celestron's .Specially i want to know from following two Indian makes which one can give me clear and bigger views...... 1) TELESCOPE SPECIFICATION : Optical Design -Newtonian Reflector. Primary Mirror- Diameter 100mm / Focal Length 600mm. F/6 (240x Power). Resolution- 2 Arc - Seconds. Visibility- Can see 12 Magnitude Star. Astro Eyepiece -1.25"OD 1) 25mm efl, 2)12mm efl. (24x & 50x). Variable Barlow- 1.25"OD (1.5x = 2x = 2.5x = 3x). (36x to 150x in conjunction with above eyepiece). Finder -Gun sight for quick alignment. Eyepiece Mount- RACK-AND-PINION Focuser 1.25". Stand / Mount Metal Table Top (AZ Mount) 2)TELESCOPE SPECIFICATION : Optical Design - Newtonian Reflector. Primary Mirror Diameter 80mm / Focal Length 800mm. F/10 (192x Power). Resolution- 1.5 Arc - Seconds. Visibility - Can see 11 Magnitude Star. Astro Eyepiece -1.25"OD 1) 25mm efl, 2)16mm efl, 3)12mm efl (32x, 50x & 66.6x). Variable Barlow -1.25"OD (1.5x = 2x = 2.5x = 3x). (48x to 199.9x in conjunction with above eyepiece). Finder - 7 x 25 Achromatic finder (spring loaded 2 point easy collimination. Eyepiece Mount RACK-AND-PINION Focuser 1.25". Stand Metal Tripod Stand 32" height. (with mount 36"). Mount Altazimuth Metal Mount with partial locks. 3)Celestron powerseeker 114 or 127 EQ. which one of above 3 is best.I live in a town where air pollution is moderate,and night light illumination(street lights ) is also moderate.

1. The most important specification for any telescope is its aperture: the diameter of its primary mirror or lens. The apertures for these telescopes are 100mm, 80mm, 114mm, and 127mm, so the last one will be the best. There is a problem with this telescope: it uses a seriously flawed optical design called the "short tube" which makes it hard to collimate and gives blurry images. The 114mm version is a traditional Newtonian and has better optics. Both Celestron telescopes come on shaky hard-to-use equatorial mounts, and I would not recommend them for that reason. The Startracker mounts don't look very solid in the photographs. Look instead for a Newtonian reflector with at least 150mm aperture mounted on a simple solid Dobsonian mount, such as this: http://www.tejraj.com/skyquest-xt6.html If that's too expensive, consider this one: http://www.tejraj.com/starblast45.html Both of these will be much better than the scopes you are considering; I have tested both these personally. Here are a few web pages with good information on beginner's telescopes: http://www.gaherty.ca/tme/TME0702_Buying_a_Telescope.pdf http://www.scopereviews.com/begin.html http://observers.org/beginner/j.r.f.beginner.html For more advanced information, read Phil Harrington's Star Ware, 4th edition (Wiley). You'll get the greatest value for your money with a Newtonian reflector on a Dobsonian mount, such as these: http://www.telescope.com/control/category/~category_id=dobsonians/~pcategory=telescopes/~VIEW_INDEX=0/~VIEW_SIZE=1000000 http://www.skywatchertelescope.net/swtinc/product.php?class1=1&class2=106 Buy from a store which specializes in telescopes and astronomy, either locally or online; don't buy from department stores, discount stores or eBay as mostly what they sell is junk. Find your local astronomy club and try out different telescopes at one of their star parties: http://www.skyandtelescope.com/community/organizations I strongly recommend that beginners steer clear of astrophotography until they have learned their way around the sky. Astrophotography is by far the most expensive and difficult area of amateur astronomy. Many people who buy telescopes have no idea how to find interesting things to observe. A good introduction to finding things is NightWatch by Terence Dickinson (Firefly). A more advanced book is Star Watch by Phil Harrington (Wiley).
2. AND- one of these are on a tripod alt az mount, the other is on an EQ mount which beginners should NEVER buy as a first telescope mount.. Read what Geoff wrote and then read these two web pages. I would recommend that you NOT buy either telescope because of the mount. http://www.texasastro.org/telescope.php http://www.texasastro.org/mounts.php
3. In ancient times, how our elderers found that , how many planets and even saturn's dust circle ?? If u know pls convey to animanod@yahoo.com
4. First one..
