Quick Overview

  • Modified Four Element Double ED Petzval design eliminates astigmatism, coma, secondary spectrum, spherical aberration and field curvature.
  • The Takahashi FSQ106EDXIII F5 Astrograph Telescope provides 153mm of backfocus to accommodate demanding applications.
  • Prime focus 88mm image circle covers 9.5 of sky and accepts new F3.6 focal reducer!
  • The Takahashi FSQ-106EDXIII Telescope includes built-in camera angle adjuster capable of lifting up to 11 pounds and supplied adapters that will allow you to attach camera rotators like the Astrodon Takometer right out of the box.
  • Included 4" rack and pinion focuser with over-sized knobs and 10:1 micro-focuser
  • The FSQ-106EDXIII Refractor is airline portable at only 16.7" long!
  • The only difference between the EDXII and EDXIII version is the complete lack of the "Captain's Wheel". In its place is a casting. Backfocus, etc. remain the same.
  • Five Year Manufacturer Warranty

Takahashi FSQ-106EDXIII F5 Astrograph Telescope - Imaging Edition

Remember, the "XIII" version of the FSQ-106ED is the same as the New Q, but comes with different adapters so that you can attach a camera rotator out of the box. This adapter eats up 25mm of back focus (178mm vs 153mm). The information below refers to the standard version of the FSQ106ED.

Introducing the Takahashi FSQ-106! The last rendition, the FSQ106N, has long been regarded as one of the finest refractors available for film and CCD imaging. Wide field, large image circle, excellent color correction and a flat field were just some of the notable points of the previous FSQ106N.

Now, enter the Takahashi FSQ106ED F5 Astrograph Telescope...

The new Takahashi FSQ106ED telescope has made some significant improvements over its predecessor. Let's start with a significantly longer backfocus at 178mm to accommodate most CCD systems. Many CCD imagers have additional equipment in the light path such as filter wheels, adaptive optics, temperature control focusers and other accessories which take up precious focus travel. Thanks to a new design, the FSQ106ED provides the additional backfocus to accommodate most CCD equipment and even allows the use of binoviewers!

The Takahashi FSQ-106ED telescope comes equipped with a newly designed heavy-duty 4" focuser with a built in camera angle adjuster. Designed for all applications in mind, the focuser will lift up to 5kg, or 11lbs, and keep it there without slipping. Do you need to make precision adjustments in focus? No problem. Takahashi has thought of that, too... And that's why they've included a micro-edge fine focuser with a 10 to 1 ratio. Combine that with both 2" and 1.25" eyepiece adapters and you're ready for any application.

But, improvements haven't stopped there. Takahashi has redesigned the optical system in the Takahashi FSQ106ED F5 Astrograph Telescope to a modified four element double ED Petzval system . By adding a second doublet inside the tube, the optical wavefront can be optimized to remove any astigmatism - this in turn acts as a field flattener. The Takahashi FSQ106ED F5 Astrograph Telescope optical system is incredible for imaging - providing wide, flat fields, high contrast and no lateral color, yet it is also capable of outstanding visual work. Use the optional F3.6 (wow!) focal reducer for imaging applications and the optional Extender-Q for visual use at F8. What's more, at prime focus you get 88mm of image circle which takes in a full 9.5° of sky. Now, that's an image....

Do you need more? Then think on this... Another improvement on the new Takahashi FSQ106ED is the enhanced portability from the new, retractable, self-storing dew shield design. The Takahashi FSQ106ED is now airline portable at only 16.7" long when the dew shield is collapsed and stays in a tidy package by measuring in at a total length of only 20.5" when fully extended. Inside the all aluminum tube, you'll find knife-edge baffles block off axis light and provide maximum contrast. Outside you'll find the perfect fit and finish with its rich ivory color and ebony trim. The focuser and the aluminum castings will continue to be made one at a time for consistent, optimal quality. That's a Takahashi quality guarantee.

Important Note: Takahashi America requires that their telescope optical tube assemblies be shipped via 2nd Day Air or faster in order for the full warranty to be in force. Please make sure you choose the appropriate shipping method in your shopping cart or, if you speak to an OPT associate, request 2nd Day Air or faster. If you are purchasing a telescope and mount package or any accessories to accompany an OTA, please contact OPT for a shipping quote, since only the OTA is required to ship second day air but all other products can be shipped separately via any other available shipping method. Thank you!
