TAKAHASHI
FSQ-130ED
Flatfield
Super Quintuplet APO |
|
Staying true to Takahashi's legendary and supreme optical
designs, the FSQ-130ED produces a perfectly flat-field. By
utilizing a five element design which incorporates 3 ED
elements made from premium optical glass, color, brightness
and contrast are at its best. At prime focus, the 130ED
produces an incredible Ø110mm image circle. The stars in the
center of the field are 2.0μm and only 4.5μm at the edge of
an Ø64 circle. The high contrast images produced are
extremely sharp and are 92% illuminated.
The Takahashi FSQ130ED is the ultimate astrograph. A
quintuplet super-low dispersion optical design which uses
specialized anti-reflection coatings to transmit the the
maximum light to your camera sensor. It's also the perfect
image travelling companion! At only 550mm long and very
lightweight, it is easily supported by a medium-duty mount.
175mm of back focus allow for easy adaptation of long focus
imaging set-ups.
Included with the FSQ 130 APO optical tube is a 5" focuser
capable of heavy-duty work loads. Your heavyweight imaging
set up is in safe hands. Integrated is a camera angle
adjuster and rotator for optimal camera sensor placement.
The Takahashi RD-QE .73x can be used with
the FSQ-130ED and will produce colour rich images across a
flat field and a Ø44mm image circle.
The Extender-ED when used with the
FSQ-130ED offers larger image scale for smaller objects at
980mm
The EXQ-1.6x is well suited to be used with
the FSQ-130ED for greater image scale. Stars produced by the
EXQ are small.
The FSQ-130ED was designed to produce a large highly
illuminated flat field that is perfect for larger chip
cameras that require larger illuminated fields. This design
is the next step in the evolution of the Takahashi FSQ
Series astrographs. The outstanding performance of the
FSQ-130, its portability, high quality construction and
outstanding images makes this instrument an a formidable
imaging platform.
