in manualul de utilizare scrie cam asa ceva : 

" To use the Barlow lens with refractors, remove the diagonal and insert the Barlow directly into the focuser tube.
You then insert an eyepiece into the Barlow lens for viewing. You can also, insert the diagonal into the Barlow lens
and then use an eyepiece in the diagonal but you may not be able to reach focus with all eyepieces. "

Ce este acela " diagonal " ????
