William Optics Adjustable 0.8x Focal Reducer & Field Flattener
An Astrophotography Upgrade for Your Telescope!
Adapt the superb optical performance of your compatible William Optics Gran Turismo, ZenithStar, or Fluorostar refractor for even more stellar frame filling shots with this corrective optic! With premium fully multi-coated Ohara glass used, your premium refractor will cover 97% of a full-frame sensor with great illumination and sharp star shapes. If incredible images are your goal, then the William Optics Adjustable 0.8x Focal Reducer & Field Flattener is for you!
The Gran Turismo, Fluorostar, and ZenithStar refractor lines from William
Optics feature elegant imaging potential from their premium triplet and
doublet optical designs, and with the William Optics Adjustable 0.8x Focal
Reducer & Field Flattener you can unlock flat field and fast images from some
of these striking scopes! This corrector can provide this transformative
experience to William Optics' Gran Turismo 81 (IV and WIFD) and 71, Zenithstar
81 (Original and WIFD), and the Fluorostar 91*. With Ohara glass, this
corrector compliments the FPL-53 APO optics of these telescopes excellently;
ensuring that your images are not just flat out to 97% of a full-frame sensor,
but also remain sharp and detailed. Your images will also take on a wider and
brighter perspective, with the 0.8x reducing factor expanding your field of
view around 1.25x and increasing the illumination hitting your sensor for the
same exposure time. This allows you to capture more of expansive nebulae and
deep sky objects, or add more surrounding context to them, in less time!
Installing the corrector is straightforward, with M63 threads that install to
the threaded adapters or behind the visual back included with your scope. For
your equipment the William Optics Adjustable 0.8x Focal Reducer & Field
Flattener features the common M48 threaded connection, an adjustable design
that allows you to connect common 55 mm imaging trains, as well as a 2"
filter cell on the telescope side that makes one-shot color or single filter
mono imaging possible without additional accessories!
*Please Note: The William Optics Fluorostar 91 FPL53 Triplet APO Refractor
requires an additional spacer, sold separately, in order to use this
corrective element. For an all-in-one Fluorostar 91 corrector package,

Focus Your FPL-53 Refractor For Fantastic Photos!
Take the premium FPL-53 optics of your premium William Optics refractor to a new level of astrophotography excellence and capture wider, flatter, and brighter awe-inspiring images of the incredible objects in our night sky!
An Incredible Adjustable Imaging Adapter
With an Ohara glass powered three element 0.8x reducing correcting design,
your results with this corrector are sure to be stellar! Covering a wide
range of telescopes has been realized in part with an adjustable system,
which allows you to add 9.1 mm of additional spacing to your optical train
for stellar shots with an industry standard 55 mm train no matter which of
the four scopes you're using. Once properly set, your GT81, GT71, Z81, or
FLT91 will illuminate a full-frame image circle with a 97% well corrected
and faster 381 mm, 334 mm, 447 mm, or 428 mm focal length view
(respectively) of the universe. At f/4.7 your Gran Turismo and Fluorostar,
or f/5.5 for the Zenithstar, telescope will bring dynamic and crisp images
even quicker than before; making the William Optics Adjustable 0.8x Focal
Reducer & Field Flattener an accessory that helps you create images that are
more impressive corner-to-corner, faster!
