This version of the NEW Q model includes the camera angle adjuster for the FSQ-106ED to allow the use of a remote rotation device for cameras. This model is the same price as the ED model. It sacrifices 25mm of back focus for remote imaging ease. If imaging is on your mind, THIS is the model to purchase.

NOTE: This new EDX model is designed to handle heavy cameras, filter wheels and electronic focusers and the Astrodon Tak-O-Meter for remote rotation of the camera.


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.
