Fluorostar 132 Ultra Flat—The 0.79x FLT132 Full-Frame Corrector!

With large 132 mm air-spaced triplet optics featuring FPL-53 glass, the
William Optics Fluorostar 132 Refractor sports some serious optical
performance. Now you can distill this visual optical power into an
astrophotography experience, with the William Optics Ultra Flat 132 and 0.79x
Reducer for FLT132! Adapt your APO for astro photos with this premium three
element reducer!

At 910 mm of focal length, the William Optics Fluorostar 132 Triplet Refractor
offers a crisp and clear, but constricted, view of larger targets like the
East Veil Nebula or the Soul Nebula. With this Ultra Flat 0.79x Reducer,
targets like these will have more room to breathe in the frame while
maintaining the sharp apochromatic performance of the FLT132’s 132 mm f/6.9
air-spaced optics unassisted. This is designed to easily install on the
FLT132, and provides a full-frame image circle along with a M54x0.75
connection for integrating your full-frame dedicated astrophotography
camera and accessories!

Please Note: This flattening reducer is designed for the industry standard back focus of 55 mm. While it does not feature backfocal adjustment functionality, William Optics indicates small adjustments can be made by inserting a PVC spacer between the end cap and main corrective element housing.

Augmenting Ultimate APO Optics
This 3 group, 3 element, flattener-reducer from William Optics will
reduce the focal ratio of your FLT132 refractor by 0.79x, bringing the f/6.9
optics to a speedy f/5.5. This increases the relative brightness of your
images, allowing for faster signal collection across a flattened image
circle of 43.2 mm. Additionally this will increase your scope’s field of
view from 910 mm to around 720 mm, providing more space to frame up larger
deep sky objects or provide more context around smaller celestial bodies.
