Upgrade Your Gran Turismo Astrophotography Experience
William Optics’ premium Gran Turismo line of refractors sport excellent
optical performance, with FPL-53 glass providing super low dispersion
apochromatic views from air-spaced triplet designs. With the 1x Flattener for
GT71 and 81 WIFD telescope you can harness this superb performance for full-frame
astro images with a dedicated corrective optic. Seamlessly adapt your Gran
Turismo for astrophotography today!
The Gran Turismo 71 and 81 line of telescopes are equipped with optics capable
of capturing larger targets like the North American Nebula and both the Heart
and Soul Nebulas when paired with full-frame sensor cameras, or the Elephant’s
Trunk Nebula and California Nebula with APS-C sensors. To ensure you’re
capturing these stellar objects in corner-to-corner crisp and clear detail
however you’ll need a flattener that’s up to the task, which is where this
corrective optic from William Optics comes in! Designed for the Gran Turismo
line, this Flat GT connects easily to your GT71 or GT81 WIFD*,
providing an M48x0.75 camera connection for connecting your astrophotography
imaging equipment and accessories. With a 44 mm image circle, this flattener
can provide cameras up to full-frame with well-corrected and stellar views!
*Please Note: The William Optics GT81 WIFD requires the
M92 4″ Focal Extender
(sold separately) for use with this flattener.
