Takahashi FSQ85ED F5.3 Astrograph Telescope

The Takahashi name 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 these fine instruments.

Now, enter the Takahashi FSQ85ED F5.3 Astrograph Telescope...

The "Baby Q" Takahashi FSQ85ED telescope is the newest and 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. Easily airline transportable at 12.68” [322mm] collapsed, the FSQ-85ED will fit under an airline seat or fit easily into an overhead compartment for ultimate portability. Take the Tak Baby Q to Chile to image the Magellanic Clouds or to a remote site anywhere in the world. At less than 9 pounds, a small, high quality mount turns it into a traveling astrophotographer's dream. 

Let's start with a significantly longer backfocus at more than 200mm to accommodate most medium format CCD systems. Many CCD imagers have additional equipment in the light path which takes up precious focus travel. Thanks to a new design, the FSQ85ED provides the additional backfocus to accommodate most medium CCD equipment, your digitial SLR and even allows the use of binoviewers!

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. Do you need to make adjustments? No problem. Takahashi has thought of that, too... And that's why they've designed the adjuster to rotate a full 360° without loss of critical focus. Check out the Takahashi FSQ85ED System Chart for a quick tutorial on connecting accessories to the Baby Q.

But, improvements haven't stopped there. Takahashi has 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 optical wavefront can be optimized to remove any astigmatism - this in turn 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, yet it is also capable of outstanding visual work delivering a whalloping 7.0° of sky in a compact package. Color correction from the near UV to the near IR insures tight stellar images across the entire color range. Use the optional Takahashi Extender-ED focal reducer for imaging applications to or to increase focal length for high power viewing. Now, that's a stellar image....

Do you need more? Then think on this... Another improvement on the new Takahashi FSQ85ED is the enhanced portability from the new, retractable, self-storing dew shield design. The Takahashi FSQ85ED is extremely airline portable at only 12.68” long when the dew shield is collapsed and stays in a tidy package. 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 white color and ebony and scarlet trim. The focuser and the aluminum castings will continue to be made one at a time for consistent, optimal quality. That's a Takahashi guarantee.

Review by Chris Thomasel / (Posted on 11/21/2010)

The FSQ85 Takahashi is a new downsized version of the popular FSQ 1 06 astrograph. I recently had the opportunity to test it visually and thought I'd post some impressions of this new scope. I've owned probably a hundred telescopes in my life and have owned or used probably every Takahashi scope ever made.

The first thing you'll notice about the FSQ85 is that it's really compact, 16 long with the sliding dew shield pulled back. There's a nice thread-on cap on the back of the scope. Standard equipment includes the camera angle adjuster and the micro focuser, so you're getting about $500 worth of added accessories with the tube.
I mounted the scope using the standard clamshell ring tube holder to an Orion Sky View Pro mount. The mount easily handled the scope's 8 pounds plus a couple more pounds with the diagonal and eyepiece.

First night out I noticed that you really don't need a finder scope, with only 450mm of focal length you just drop in a 25mm eyepiece andyou're at a whopping l8x! So I just aimed it roughly looking down the tube and used the low power to center any object quickly.

The scope was subjected to a bit of shake and bake on the way home since I transported it in the trunk of a motor scooter. If you had, any worries about losing collimation through vibration or heat you can forget about it. This scope is tough.

First night out Jupiter was up and about 45 degrees high so I took a look at it first. The scope has a short focal length so I used the Takahashi 1.5x extender and a 6mm eyepiece for about 113x to start with. The Baby Q shows no color whatsoever inside or outside of focus. It snaps into focus beautifully. I counted 11 bands and zones with minor striations and detail visible in moments of good seeing, not bad for an 85mm telescope! Contrast is really amazing with this scope the closest I can remember to this scope is the old FCI00N from 20 years ago. The details on Jupiter just jump out at you, you'd swear you're looking through a really exquisite 4 refractor. The moon was also impressive, the scope is very well baffled, you can put the moon just outside the field of view and the field of view is black. No color fringing on the moon at all, just perfect.

Focus travel was very generous on the scope, every eyepiece I tried came easily to focus even using Barlows and the extender. I'd say that focus travel is a non issue on this scope.

The scope was compared side by side with a 5 Maksutov and really there's no contest, the Takahashi was much sharper although the Mak had a brighter image. The Baby Q also 'cooled down really fast. It was at optimum performance in a matter of a few minutes after being taken outside.
I know many people will buy this scope to use as an astrograph. I think there are a lot of people who might want to take a look at this scope for a portable scope for visual Use. Physically just a bit bigger and heavier than a Sky 90 it packs the performance of a good 4 refractor into a tiny package. The scope reminds me a lot of the old FCT76 but much better in performance. At first glance the $2995 price might seem a bit pricey for
an 85mm telescope but this scope is one of those exquisite instruments that come along only rarely. After looking through the Baby Q I'd have to say it's money well spent. This scope IS very impressive.
