We found that the StarSense Explorer LT 114 is built sturdily and operates smoothly when slewing from one target to another. The scope needs to be manually operated, so you don't get the ease of tracking that computerized telescopes would offer. However, some skywatchers prefer the hands-on versus electronic approach, and what's more, the price is lower.
Beginner Level - Suited for a wide range of uses, these products are simple to operate and set up. Some initial assembly may be required depending on the type of product. Optical instruments with this rating will have very good optical and mechanical quality. Great for families, young people, and folks who don't want to mess with equipment and complexity. Beginning level telescopes will show you countless lunar craters, Saturn's rings and a myriad of star clusters and nebulae! Referring to the manual is recommended.
As shown in the formula below, a smaller eyepiece gives you a higher magnification. Theoretically any telescope can be set to any power, but practically speaking there is a limit before the image gets too dim and fuzzy. The maximum theoretical magnification can be estimated by multiplying the aperture (in inches) by 50. So for a 2-inch telescope, the maximum theoretical magnification is about 100 power. A 6-inch scope may be able to go to 300 power. But every time you double the magnification, the brightness drops by 4 times.
The backyard telescope is not just limited by the scope itself but also the sky conditions. When magnifying celestial objects, you're also magnifying the blurring effects of the Earth's atmosphere. So even for big backyard telescopes the practical magnifying limit is really around 250X on a good night, less on a not so steady and clear night. So don't fall for the marketing claims of those cheap flimsy scopes with \"400X\" printed on the box.
A popular type of scope these days are the \"Go To\" telescopes. These have computerized mounts that allow them to point all by themselves. They're often marketed as a simpler scope, great for a novice. But sometimes that's not true. The early models (back around the turn of the 21st century) were somewhat complicated to program and set up. The Go To scopes normally have to be aligned to the sky before use, so you will need some basic knowledge of the stars in the sky. For some people, part of the fun and joy of a telescope is manually finding the many faint deep-sky objects. Many deep-sky objects just look like faint fuzzy smudges anyhow, so if the scope does all the work it can take away some of the fun. But it's really a matter of opinion. Experienced astro-photographers enjoy the speed and accuracy of a Go To so they can spend less time hunting and more time photographing.
The Dobsonians are mounted on an altazimuth platform. To point your OTA towards your chosen target in the sky, you will first have to manually orient the telescope to the right or left by gently pushing the azimuth turntable. Then you will need to adjust the altitude axis by turning the control knob on the side of the rocker box, which allows you to move the optical tube up or down. Once you have your desired target in the centre of the eyepiece, you can tighten the control knob to hold the tube in place.
I have The Cratered Moon Astronomical Observatory which I founded on Wednesday March 5th,1986 and I have 9 different telescopes and my largest telescope I have is a Apertura DT12 inch dobsonian reflector telescope. I have 5 reflector telescopes and 4 refractor telescopes. I have a 5 inch Computerized telescope and 3 dobsonian reflector telescopes 8,10,12 I have a criterion Rv6 inch Dynascope telescope that is 35 years old.i have been keeping Astronomical records for 39 years now and I have been using telescopes for about 44 years,now.My Observatory is now with fourteen thousand dollars .I am now 57 years old and live in Blountstown Florida in the United states.
The best Dobsonian telescope for you is whichever one you can afford. If you have more than a thousand dollars, get a 12 inch dobsonian. You can absolutely make that work, as long as you can handle the bulk and weight. 59ce067264
