Recommended Accessories

William Optics Flattener 68III
If you'd like to flatten the field when doing photography through the FLT 132, this field flattener will do the trick. It has adjustable back focus, accepts 2” filters, and presents M48 threads on the camera side and M92 threads on the scope side. The APO design and Ohara glass produce amazing results.

William Optics 0.72x Reducer/Flattener 8
If you want to reduce the effective focal length of the FLT 132 to f/5 while also flattening the field, check out this adjustable 0.72X reducer/flattener. The triplet APO optics are made with Ohara glass for beautiful results. It is designed with full frame cameras in mind, and has M92 threads on the telescope side to fit the FLT 132. Image circle with the 132 is 44.4 mm and back focus is 63.4 mm.

William Optics 0.8x Reducer/Flattener
If you want to reduce the effective focal length of the FLT 132 to f/5.6 while also flattening the field, check out this adjustable 0.8X reducer/flattener. The triplet APO optics are made with Ohara glass for beautiful results. It is designed with full frame cameras in mind, and has M92 threads on the telescope side to fit the FLT 132. Image circle for the 132 is 44.4 mm and back focus is 69.24 mm.

William Optics Dura Bright 2" Carbon Dielectric Di...
The F132 is great for imaging, but it also makes a wonderful telescope for visual use! To use the scope visually, you’ll need a diagonal. We suggest the William Optics 2” carbon fiber diagonal for its flexibility and quality. You can use standard 1.25” eyepieces, or take advantage of more light throughput with 2” eyepieces.

Apertura 2x ED Barlow Lens - 2"
A 2X Barlow is one of the most popular telescope accessories available because it doubles the magnification of any eyepiece! Since this is a 2” 2X Barlow with a 1.25” adapter, it will work great with both 1.25” and 2” eyepieces, but does need a 2” diagonal or focuser to accommodate its larger 2” insert barrel. Grow your magnification choices quickly by adding a good 2X Barlow to your accessory case.

Tele Vue 27 mm Panoptic 2" Eyepiece
The Tele Vue 27 mm Panoptic eyepiece, with its classic 68-degree field, will produce 34X when used with the FLT 132. Add a 2X Barlow and double the magnification to 68X, then use the Barlow with any other eyepieces you add to your collection.

William Optics Red Dot Finder Kit with Vixen Style...
Make locating objects easier by mounting this sturdy red dot finder to the FLT132. Because the William Optics RDF offers a choice of reticles, you can match them to the type of object you're viewing and then adjust the brightness to allow you to easily center the object in the finder’s reticle.
