How does the sv406p add barlow lens with different eyepiece to focus ？

There is a use sv406p spotting scope user asking whether it is possible to install a Barlow lens on the above one?

I installed a 2x barlow lens , and the different effects seen with different eyepieces

It turns out that the Barlow lens can be focused, and the picture below is the difference in the effect of different eyepieces of svbony

The following is a comparison of the effects of different eyepiece imaging:

The test result is that sv406p can be connected to 2x Barlow lens magnification, and can be connected to other eyepieces for focusing imaging
