Cred ca sint instrumente mult mai proaste si mai scumpe ,. Ca si oglinda sferica , nu e o tragedie la 150mm si aceea lentila corecteaza imaginea si prelungeste artificial focala , dar folosesti oculare cu focala mai lunga . E special pentru terestru si imaginea apare dreapta .  

 The 31.7mm (1.25&#8220;) 1,5x Erecting Eyepiece produces an upright and side correct image. This is of particular importance for terrestrial viewing, because usually the image would appear upside down in an astronomical telescope. You can use it for unforgettable terrestrial observations. Animals, birds and landscapes can be seen in unimaginable precision, even over great distances.
