Barlow common sense:
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 observation effect appears nearly zero or blurred
