What kind of functions that are hoping to see? A 80 mm would be enough to see the red spot on Jupiter and the rings of Saturn. You may use the Cassini division in the rings, but. It should also be able to see cloud bands of Jupiter. Looking at Mars, so they may be able to dark spots in an excellent position to see to see, but Mars is a difficult issue for everyone. We have seen that Venus is the phase due to the "Everything is dark clouds. Mercury is a tough task too small to see anything. Uranus and Neptune is blue. You will not see Pluto.
ReplyDeleteHope this helps!
I looked through the territory of more than 40 years. A telescope of 80 mm is a powerful all over the world for its) over-f (ratio of focal length relationship and the diameter of the lens. However, the purchase of the brand is of good quality. The goal is the actual conditions of seeing. Increased by enlarging the image is the optical defects.
ReplyDeleteInch by inch, a reflector less expensive, but is a bit complicated for beginners because of its foldable design. Not only planet with the full scope. There is a lifetime of observation, the scope of which an 80mm refractor or a reflector. I have areas of 6 cm to 14.5-inch reflector. It is the range of 6 cm is the most commonly used.
Hello Derek,
ReplyDeleteI understand that you look at the Orion 80mm ED or a similar pattern? They have areas of Nice. Forget the answer insisted that the extension is important. You want openness. 80mm is enough to show some properties of the planet. Nice and delivers sharp images. However, if this is its scope should be disappointed that after some time and want more. Can I make a suggestion?
To http://skyandtelescope.com/resources/org ... and find your local astro club. Go to one of their public nights. You can search through many areas. Someone will probably be an area in the same class as the scope of the ED 80 mm () in some models of television sets. You will see through them and they in comparison to other areas. And since people are always looking for the update will probably try out a good piece about a topic before you can buy.
By the way, if you enjoy the moon, trying http://groups.yahoo.com/group/lunar-obse ...

No ... identified the lens of 80mm diameter. The larger the diameter the more light they can. and it provides a better view faint objects such as nebulae. The performance of the telescope is the value that the increase shows, but with a 80mm lens, it collect enough light to see much. You can check a telescope instead. Dollar for dollar, which collects more light and provides further development of a refractor.
