Are 5x Barlow lenses any good?
In my case, this barlow lens and bundled high power eyepiece together gave about 120% of the maximum, and image quality get degraded a little. At such a bargain price, it gives 5X magnification power with good enough image quality. With low power bundled eyepiece attached to this lens, image quality is quite good.
What is the difference between a 2x and 5x Barlow lens?
A 10mm with a 5x barlow is equivalent to a 0.2mm ep. A 25mm with a 2x barlow is equivalent to a 12.5mm ep. The barlow 2x or 5x is a magnifying multiplier, not an eyepiece focal length multiplier.
What does Barlow 3x lens do?

The specification of the cheaper 5x barlow is a little vague. All we can determine from the listing is that it has multi coatings, a t-thread and apparently apochromatic.
