Great Quality/price for F4 Newtonian
Got the 17mm. Very sharp and contrast eyepiece tested on the moon and DSO. Great quality for low price. No distorsion apart the coma that fast newtonians produce. A very great alternative to the eyepieces that come with new scope. Offer great TFoV with short ratio scope.
noticeable upgrade compared to simple eyepieces
I own the 6mm, 12mm, 17mm and 25mm Svbony Plössl.
They feel good and the picturequality is pretty good. they also convince with their coated lens and the black thread which leads to non-reflective images. they are not completely free of distortion (that is hardly any eyepiece) but for the price they are a huge step up compared to simple set eyepieces.
Its a a purchase recommendation without a doubt!
