TAKAHASHI TOA-130NS / NFB
Spectacular Visual And Imaging Performance!
 

TAKAHASHI Engineers have been designing the best Apochromatic Refractor optics for a very long time. In fact TAKAHASHI optics in general are well-known for their HIGHEST CONTRAST, PERFECT COLOUR CORRECTION, and SUPERIOR SHARPNESS! But there is more - TAKAHASHI 'TSA' and 'TOA' series of Refractors show and UNMATCHED STREHL RATIO 0.998! This means that these Refractors are within 99.2% of perfection!! When we think that a 0.95 Strehl Ratio is considered excellent, it is no wonder that an article in ASTRONOMICS concludes by saying:

"...QUITE SIMPLY PUT, THE TAKAHASHI 'TOA' AND 'TSA' OPTICS HAVE NO EQUAL!"

 
The Takahashi TOA-130 is the first of Takahashi's newest optical design: The Ortho-Apochromat. This 21st century innovation employs a newly designed triplet using special elements to produce the highest order of colour correction. Orthoscopic means perfected visually and Apochromatic means you're free from those strange violet glows which often accompany bright stars or planets. Thanks to the ingenious design of layering an FPL-53 Extra-low Dispersion glass element between two extreme quality crown and flint elements - perfection ensues. And what's more, it's air spaced, so there's no oil between the elements to leak or become opaque with age. The lens cells are durably constructed to withstand transport - yet are fully able to be collimated should the owner wish to make adjustments. With 1/12th wave accuracy and a Strehl ratio of 0.998, the optics on the Takahashi TOA-130NS Ortho-APO are as near to perfection as you can get!

The Takahashi TOA-130 Ortho-APO is a dream come true for those who want to use a medium format camera. It includes a deluxe 2.7" focuser. The 2.7" focuser will produce a usable 40mm diameter image circle for virtually unvignetted 35mm prime focus photography and a large thumbscrew locks the focuser tube in place without image shift. But that's not all. The focuser itself offers a generous 222.5mm of backfocus to allow the use of additional accessories, like adding on color filter wheels, etc. What's more, the focuser itself offers "no slip" stability with dual knobs for ease of use and 2" threaded eyepiece/accessory holder with 1.25" compression ring eyepiece holder also supplied - along with Scopeguard finder quick-release.

The Takahashi TOA-130 Refractor is perfect for visual, CCD and classic astrophotography. The f/7.7 focal ratio with a 1000mm focal length is long enough (using the optional LE-ED 2.8mm Takahashi ocular, for instance) for high magnification observations of the Moon and planets and yet will produce a 2.5° field at 20x when used with the optional Takahashi flat field LE-50 2 " ocular. The high order of colour correction of the Ortho-Apochromat Series produces images with saturated colour and, thanks to the numerous knife-edged baffles, it also displays an image with amazing contrast - all packaged in a short, 32" tube with the dew preventive lens shade retracted that weighs only 22 pounds.

Some of the many comments from our TOA-130 customers
“The TOA-130NS is nothing short of fabulous, it is easy to use, performs beyond my expectations, and is built to last a life time. This is a scientific instrument, and I only just beginning to learn how to use it. I took my first photograph using a standard DSLR, nothing flash, just the moon from my back yard. But the result was stunning, a friend of mine even published it on her web site in Spain, she was so impressed!”
(Garth Hayter - Adelaide, SA)
 
“Boy, am I happy with the TOA-130NS images of the moon and planets. Simply stunning in clear steady moments Claude, with wonderful contrast. I see detail which does just not show in other telescopes, giving me everything I need to stimulate further study of Lunar science. Everything I had hoped for in a Lunar and planetary scope and more, definitely!”
(W. Herbert - W.A)
 
“...I am looking at purchasing a TOA-130 soon - have looked through one, and perfection comes to mind. Will check out the new range of TAK-UW Eyepieces.”
(S. Welfare)
 
“TOA-130: ...The packaging is just fantastic. There is no chance that this scope was going to get damaged in transit. Very well engineered. Now the scope, holy cow, it is enormous. It looks way way bigger than my TSA102. Not just 30mm.

But, as with the TSA it is an awesome sight. The focuses is enormous and super smooth. The finish is amazing, beautiful shiny tube. And the castings are just a work of art. Almost everything is oversized, so should be easy to adjust things, even with gloves on a cold night. It is now sitting with the rings and top plate attached on the dining table. I have spent a fair amount of time ( hours) just looking at it.

It is just a wonderful sight. For all the reports I have read as a part of my research which are glowing of the scopes optical qualities. The fit and finish are just as good. It is a world class piece of equipment. World class.”
(Peter Saunders - Elthon, North Vic.)
 
“Hi Claude, I hope all's going well for you. I had a spectacular image of Jupiter last night through the TOA-130 you sold to me, I continue to be amazed by the instrument.”
(Dr  D.Weldrake  -  A.C.T.)
 
“...Over the weekend I had the opportunity to use the new TOA-130 and I just wanted to email to let you know that I was totally amazed by the level of image quality, colour definition, clarity, sharpness and stability that the telescope was producing. I only had average seeing, but the image of Saturn was among the best I've ever had, the shadow of the rings on the planet was as dark as the background sky, and the planet's cloud details were clear. I even think I made out vague markings on Mars, which is quite an achievement when the disk is only 6 arc-seconds across. Venus suffered from the seeing but there was no false colour at all.
Star images were perfect diffraction patterns in true colour and close double stars were no match for the quality of the optics.
So I wanted to email to thank you for helping me to obtain such an amazing instrument.”
(Dr. D.W., ACT)
 
“…Thank you Claude for convincing me to purchase a Takahashi  "TOA-130" refractor and  "EM-200  Temma 2" mount, instead of the telescope-mount set-up I was about to buy!”  
(J. Brown,  NSW)
 
" .... Claude, the second hand TOA-130S you sent me looks as good as new, and it is an absolutely beautiful telescope!"
(Dave Stanicic, NSW)
