Hyperion-Klasse, das Maß der Dinge bei den 1.25er Zoom-Okularen. P A R F O K A L !!! Wirklich richtig gut !!!!!

Comparado con el Celestron zoom es prácticamente igual aunque con un poquito más de aumento, aunque lo probe en un NexStar 130 SLT, así que supongo que un mejor equipo se le sacaría más provecho

A zoom objective lens is quite useful but it requires a certain amount of telescope knowledge to get the most out of one. This particular lens is simple enough that a novice can figure it out with some practice and clear skies, of course. The quality is high and this same lens is more than double the price with just a different brand on it. So, do your research before paying top price for something that can cost a lot less at Amazon or similar retailers.

The product is original and was packaged very well. The Lens works as advertised and the image clarity is flawless, I own a 6mm non zoom Lens already but honestly it’s nigh impossible to find the planet correctly with such high magnification. However with this Len’s you can start zoomed out and easily locate the planets like Saturn which is very faint in an urban city, then zoom in slowly to get a crystal clear view of the planets, I could very easily see the rings of Saturn with this Lens without any distortion.
