My 15mm NPL eyepice was my first purchase to complement the 10mm and 25mm eyepieces supplied with my scope. For a relatively small amount of money it very quickly showed up the failings of those 'supplied with' eyepieces. Over the last couple of years my collection has grown to include much more expensive offerings from Baader and Televue but this humble plossl still holds its place. I now find it particularly useful for splitting double stars, where its sharp contrasty image is a real benefit.
If you're looking for that first step up from the eyepieces which came with your scope or you're just on a budget then I can't recommend these highly enough.
