Common sense of Barlow lens
The Barlow lens' role is not just to improve the image quality;it's also play an important role of viewing comfortable

Even a well made Barlow will little damage on the imaging quality

When the Barlow lens and eyepiece using together;if the magnification is higher than the maximum effective magnification of the telescope itself

the Barlow lens observation effect appears nearly zero or imaging becomes blurred
