The TOA-150NFB is the second Takahashi Ortho Apochromat to be developed by Takahashi. It features a newly designed triplet objective. This new design, like its smaller companion, the TOA-130, is absolutely color free.
The high contrast and total lack of color makes the TOA-150 not only an outstanding optical instrument, but it can be used to make outstanding images with a CCD, digital SLR or film camera. Framing the image or placing the ocular in a convenient position is made simple because of the built-in camera angle adjuster that allows the 360° rotation of the camera or ocular without loss of focus.
The new heavy duty focuser is designed to handle the new breed of heavy cameras and filter wheels. It uses a long stroke linear bearing designed to keep and hold a heavy instrument package. Like the FSQ-106ED it uses a trigger lock focus lock and new pinion assembly. The CAA and all standard adapters are still included as always.
The apochromatic triplet (double-ED objective with front and rear elements of FPL-53)(D=150mm, F=1100mm, F/D 7,33) is assembled in an extremely neat and precise barrel mechanical, entirely adjustable. Collimation is easy to realize and makes it possible to adapt perfectly the optical stresses to the conditions of observation or imaging. The tube has a retractable dewshield.
NOTE: Outside Diameter of the dew shield is 207mm.
Optical tube only. Mount and tripod sold separately.

Near perfection
For my location and needs, the TOA 150 works better than I ever anticipated. Viewing conditions in the deep South are rarely optimal. Ive been through a number of OTAs looking for one with visual and DSLR Astrophotography performance. OTAs include a number of 6, 8, 9.25, 11, 12 and 14 inch SCTs. Also 2, 3, 4, 5 and 6 inch refractors. The best refractor before the TOA was a Takahashi FS-152.
The TOA is solidly built, has awesome optics and a great camera angle adapter. The focuser is fine and is only bested by a high end FeatherTouch. For DSLR imaging this scope has to be approaching perfection. Very easy to use and has no discernible color. Even in poor seeing the results are very good.
The only negative would be the counter-weight collar. Attaching it is optional but if you choose to use it another 10 or so pounds is added to the scope weight. The objective is heavy on this scope (more quality and sturdy construction in the lens cell where you want it) and the counterweight centers the OTA a little better in the rings. Not required but a nice, if bulky, option to have.
Oh, another downside if you love to spend money and search for the ultimate scope. The TOA 150 puts a damper on that. The only other scopes in this range I would consider now would be an AP 160 and then only if my name came up and I could get one new. Then there would be a final shootout for the ultimate 6 inch refractor.

TAK TOA 150
I have used the TOA150 for a year now and there is not a single night that I look at it and thru it that I am not fully amazed at the all around quality of the hardware and the views (or images) it can produce. Absolutely zero color distortion and pinpoint stars on black velvet.The inner baffles are great at producing high contrast images.
I push this scope to viewing magnifications above 440 and I get views that are razor sharp with no haze or color fringes of any kind.
The focuser is tight and precise. The fit and finish is holding up very well.
This telescope is a keeper.

First Class Imager
Typical hight Tak quality all around. The TOA-150 is a joy to image with. Using the field flattener, I get pinpoint stars to the corners of my STL-11000. Images of the Rosette and Jellyfish Nebulae printed to 30x45 inches are stunning. I have no reservations about recommending this instrument.
FS-152 with 11/70mm finder
<p>I'm not sure about this but...... from what i hear less glass and weight is better. The finder is a dream to use it makes the nite sky jump alive. When the air currents let you up the power the planets have features.I just love it. Can't wait for a good nite Thank-you c.p.s.</p>
