The New “Q” is the redesigned flat-field super quadruplet successor to the very popular FSQ-106.

The ultra duty massive 102mm diameter (4") focuser features an anti-torquing drawtube. The focuser is loaded with ball bearings to prevent undesired torquing (rotation of the draw tube) with heavy instruments attached. Generous back focus of 178mm allows the user to attach a variety of imaging packages, bino viewers, 2" diagonals and many other visual devices.

The tube length of 16.7" allows the new “Q” to be highly airline transportable. Even when the lens shade is extended the total length is only 20.5".

The new ultra duty focuser with new camera angle adjuster/rotator will carry a 5kg (11 lbs) and be able to handle the new large chip CCD cameras. The 88mmø image circle produced by the new “Q” is 9.5° in diameter. The newly designed Takahashi micro edge focuser is included for precise focusing.

The new optional reducer changes the focal ratio to f/3.6 for wide field imaging produces a 6.5° field and a 44mmø image circle.

The redesigned modified quadruplet double ED Petzval optics has been optimized for imaging as well as visual applications.

Color correction has been extended to 1000nm to produce non-bloated imaged stars.

Note: Takahashi optical tubes are sold without tube holder (rings), finderscope, star diagonal, eyepiece, reducer, extender, mount and tripod. These extra items are sold separately.

Shipping Notice: These high-precision scopes must be shipped by air for the full warranty to apply. Air shipping charges are not included in our price, and will be added to your bill. We would be happy to quote shipping charges.
