i have the 15mm and am blown away how good it is for $75 canadian. obviously there are better eyepieces out there but not for this price! yes there is some fade at the edges but if you are on a budget you won't go wrong!

I have two of these EPs - the 15 and 6mm. The 15 is my favorite EP. Wide AFOV, great eye relief. A little fuzzy at the edges, but the wide FOV more than makes up for it. Best for open clusters and finding the faint fuzzies before cranking up the power. Also handles my Edmund 2.5x RKE barlow quite well.
The 6mm is another story. While having good eye relief and wide field of view, the internal reflections are bad. On planetary objects it's quite noticable. On lunar views it's unusable. The 6mm has a built-in barlow, which is how they get the effective short FL. Perhaps all the glass in there is causing the trouble - maybe not all the elements are coated. I don't know, but the 6mm rarely if ever gets used.

- I got the 15mmm in the mail last week. total garbage as far as Im concerned. The center of the field was sharp, but about 50% of the way out the seagulls were everywhere!!!...I immediately sent it back for an ORION highlight 20mm plossl.
