About eyepieces applicable to BT126SS-A
The removable eyepieces can be swapped for other Vixen SLV or LVW or SSW series of 31.7mm-size eyepieces, but if the
eyepieces with high magnification are used, it may give rise to misalignment that becomes detectable due to its high magnification.
It is always recommendable to use the eyepieces with focal length longer than 10mm for observing to avoid it.
