eyepiece holder for the visual observer. The
lightweight construction minimizes the weight
placed on the back of the OTA, yet provides
plenty of stiffness to support the eyepieces.
The turret is a standard part of the
Borg SWII Ultra-light Systems.
Four 1-1/4" eyepieces may be mounted, ready for
use by simply rotating the turret which
includes a click-stop position for each
eyepiece. Eyepieces are friction gripped

parfocal eyepieces are recommended.
At the rear, a straight-through port
accomodates a 2" or 1-1/4" eyepiece. This is
intended for holding a low power, wide-field
eyepiece which makes finding objects easy even
