How chooses your telescope
Foreword: Here only is chooses the telescope some suggestions, but is not the telescope teaching website, therefore only aims at generally chooses the heavy spot to put forward the proposal, regarding the telescope structure or other more thorough discussion, please refer the academic specialized website
Binoculars
1. other presumptuously thinks a telescope to look at the world beautiful scene, because, does not have any telescope is perfect ?
In the known optics domain, we believed optics product all has its limit, if you want are the effect, telescope objective lens(caliber)count for much, if wants is convenient, please take the volume as the first choice, for example similarly enjoys the bird, looked Shan Niao and the waterfowl uses not to be dissimilar, Shan Niaotsui good chooses the facile telescope, in order to avoid walksafter500 meters, discovers the telescope more and more heavily, but looks at the waterfowl, theoretically is the size each one is best, if must two choose, please &test00009-1538 like this may use higher percentage appreciation ecology it Shan Niaotsui good chooses the facile telescope (on chart)
2. should understand basic indication
If10X26mm, 10Xis10times, 26mmis the objective lens(caliber)diameter,
If8-20X50is invariable time(ZOOM), is8to20time of50mmis the objective lens diameter
3.multiples significances
In the intuition a multiple higher goal may put is biggerunder, please note the proviso
A.theoretically, is away from200meter far goal, useswhen10 time of observations may pull closer the goal to only has20meter far, with20times looked when only had10meters far, when, same caliber, the higher multiple image could darker, field of vision smaller, Xie Hsitu was also worse
B. grasps the type telescope, if indicates solidly, surpasses12time of time images to be able to rock because of both hands vibration, matches the camera foot rest fixed observation, should be possible to improve, but still had the field of vision 小影 to like and so on the shortcoming darkly, enlarged the caliber to be possible to increase brightness and Xie Hsitu
The c. surface observation limit is50times, surpasses50time of time aerodynamic disturbances the situation to be able to be very obvious, effect...
4. calibers significances
When to same multiple, the heavy-caliber brightness and Xie Hsi? the non- small telescope may compared to, when to weak light, when in particularthe night scene , early morning dusk enjoys the bird or at night heavenly body observation, heavy-caliber was easy to use
Whatdo 5. you want are
The mountaineering traveling enjoys the bird to look the giant star performed, bringsSteiner SAFARI 8x22or10X26mmvery cruel, went to sea fishes enjoys the whale, choseSteiner the Marineseriesto be right, climbed mountains goes hunting the exploration, the survival playsthe Huntingseriesis measures the best equipment for you which the body made, the night scene, observed the stars, the guard choseRANGER to match
6.compares has bought again
Each person both eyes sensitivity is different, applauds with product some people, some people call the difference, own look
