Another great Svbony product

I was looking for a wide field eyepiece for my 127mm telescope. Having good experiences with Svbony eyepieces in the past, this one seemed to tick all the boxes. Ordering was easy and the item arrived promptly and in fine shape. I'm very impressed with the build and optical quality of this eyepiece, first light was tonight, and the views were great! In my scope, it gives 25X with a 2 degree field of view, just right for star clusters like the Pleaides and Beehive (apparent FOV is 52 degrees, much better than any other 40mm plossl I've ever seen). Star images are sharp almost to the very edge of the field. All this for 50 bucks!

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!
