FC-35 Reducer 0.66x
ی
4-element FC-35 reducer 0.66x can be used
with FC-100DZ. This reducer is specially
designed for deep sky imaging, reducing the
focal length to 530mm f/5.3 and reducing
exposure time. To attach a DSLR camera,
use CA ring 102 and DX-WR or equivalent
up to a DSLR camera.
FC/FS Multi-Flattener 1.04x
ی
The FC/FS Multi-Flattener design is
▼
comprised of two elements, which allows
for correction across a larger image
circle in most FC/FS telescopes. The
flattener increases the focal ratio slightly
by a factor of 1.04, resulting in an f/8.2
system. To attach a DSLR camera, use
the CA ring 100 and the appropriate DX-
WR for your camera. It can also be used
for visual observation per the system
diagram below.
