What is the overall best portable telescope for planetery viewing? - portable refractor telescope
I have a miserable 60-mm telescope is equipped with a sr4mm 25mm Lens 12.5 mm and a diagonal of more than one Barlow, and editor. Firstly, "what good is it really good, and secondly, the size, what should I use for viewing the planet? What is the best telescope for that?. I want to know the pros and cons between a telescope and a reflector.

Portable Refractor Telescope What Is The Overall Best Portable Telescope For Planetery Viewing?

The answer depends on your budget, and his definition of the word "portable". For some, an obsession is 30 inches from the bill,

or spend as much as a telescope with high APO.

Most of us with a much smaller scale, which can be easily treated to be happy.
During the 19th Century have, amateur astronomers have been happy with a telescope of 60 mm. Half of the telescope in her hands was a 3.4-inch telescope, and was too costly.
See Chapter 1 here:

I sit here and recommend all kinds of equipment for you, but it would be rather pointless. I have many areas of 60mm and can be and is a decent look at the moon, planets and the brightest and is a very cost effective solution that can accumulate in one hand and threw it on the Web -. Thus, the expansion kept under 120x andthese areas will give you a resonably sharp images. You can be explained by your money, a ridiculous number of different but equal to or below 120x will help you, the laws of physics. (Note: The Barlow in these areas is often useless, and everything is through the purchase of a "1" to 1-1/4 "diagonal will be improved with a pair of 1-1/4" format eyepieces - like a 25 mm and 10 mm)
Upgrading to a 90mm-120mm refractor on an equatorial mount point will give you much better for the same objects at 200x. Who is so high that you can go, it makes sense, until you add a decent clock device. This increase results from the object through its field of vision relatively quickly. The equatorial mount will help you in this goal if they remain properly configured, you simply move the control of right ascension, to keep closed the target. Overall vision for the framework is a big advantage. Cubes of light large Dobs are great for DSOs large field, but tracking a planet under high magnifiction may be old - even if someDobs units can be equipped with clock and control systems, and they have no problem.
Each instrument has its own benefits and challenges, and much depends on your personal preferences. The refractors expensive and its long-Aperture, and saw objects close to the lens position Zenthe often dangerously close to the earth. The reflectors are much cheaper, especially if mounted on a mounting plate Dobs, collimating optics frequent and larger pipes are subseptable wind and temperature fluctuations. Multinational companies are a good compromise between the two and can be a great focal length and resolution in a compact and convenient.
Find a local astronomy club and make it a point to a number of these areas to treat. You may even decide to go with a good telescope. It is important to go at night and watch this great heavenly bodies show to make.
I was a heavy planetary gearbox observers for many years. I found the time to only 6 inches (150 mm) is really the minimum that can meet the overall study, although it is better 8 to 10 inches () 200 to 250 mm. The package with most notebooks I've found is the Celestron NexStar 6SE, which has 150 mm mesh into a solid support, the full scope of a weight of 30 pounds. If it is too expensive for your budget, consider a 6-inch on a Dobsonian mount, a little heavier, a little bigger and Newton becomes less tolerable, but also a very good outlook. A telescope of 6 inches with a telephoto lens Celestron ED several times more than the cost, and require the installation of large and heavy. Visually, it would be great, but it is too expensive and not very mobile.
