Product Details

  • The "Baby Q" Takahashi FSQ85ED telescope is the smallest member of the FSQ Series of flat field astrographs. Designed from the ground up for digital imaging. The Baby Q is the go anywhere, portable astrograph. Weighing less than 9 pounds and measuring 12.68” [322mm]  when collapsed, this telescope will fit under an airline seat or fit easily into an overhead compartment for ultimate portability.

    The Takahashi FSQ-85ED telescope comes equipped with a newly designed heavy-duty 78mm focuser with a built-in camera angle adjuster. Designed for all applications in mind, the focuser will lift your equipment, and keep it there without slipping. Inside the aluminum tube, you'll find Knife-edge Baffles that block off-axis light and provide maximum contrast. The scope has a significantly longer back focus at more than 200mm to accommodate most medium format CCD systems and even allows the use of binoviewers! 

    Takahashi redesigned the optical system in the Takahashi FSQ85ED F5.3 Astrograph Telescope to a modified four element double ED Petzval system. By adding a second doublet inside the tube the removing any astigmatism and acts as a field flattener. The Takahashi FSQ85ED F5.3 Astrograph Telescope optical system is incredible for imaging - providing wide, flat fields, high contrast, and no lateral color. Color correction from the near UV to the near IR ensures tight stellar images across the entire color range

    There there is also an option to purchase this telescope with the Takahashi FSQ-85EDX Flattener. This flattener will expand the corrected image circle from a 28mm diameter to a 44mm diameter to fully cover any full frame sensor.

Excellence

I always heard a Tak was the best, now I'm a believer. Visual clarity is phenomenal, but I'm mostly an astro photographer. Images have tack sharp, round stars across image APS-C and FF. No chromatic aberration I can detect. Well worth the cost. OPT delivery was great.

Amazing scope

I’ve had this scope for a few months now and it is an amazing piece of equipment. Tack sharp stars and it’s actually a great little visual scope as well as an amazing scope for photography. This little thing has really sold me on the takahashi optics and I’m looking to purchase a larger aperture tak scope now. Worth every penny. It was between this and the ***** VDS100, entirely different scopes one costing almost twice as much, both with excellent optics and I’m glad I went with the TAK. Focuser has had no issues with a zwo1600mm with the wheel or a canon eos RA. Makes me wish I had a better mount to put this fantastic scope on.....

One of the best telescopes in its class

I owned this telescope for a couple of years, and I think anyone who plans on buying this telescope is aware of its reputation. Considering that it costs several times that of its counterparts in the aperture range, it isn't exactly a telescope for everyone. However, if you want the absolute best quality in a portable package, it doesn't really get better than this. One of the main reasons I purchased this telescope is speed. Few refractors go below f/6 at native, let alone f/3.x when reduced. At f/5.3, not only is it fast, but it delivers perfect star images from edge to edge, focused into tiny pinpricks. When reduced with the 0.73x reducer, the stars aren't as tight as at f/5.3, but still very small by conventional standards. The FOV when reduced is huge, especially when coupled with a chip that maximises its image circle. While there have been many complaints about Takahashi's focusers, I found the focuser on my FSQ85 to be sturdy and free of flexure. The camera angle adjuster, notorious for introducing tilt, worked perfectly on mine.
