The TOA-150 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 179mm oversized tube was used to provide superior baffling and extremely high contrast. Knife edged baffles inside the tube help provide this great contrast.

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 smooth heavy duty retractable lens shade allows the length of the TOA-150 to be reduced to 38° for easy transport to remote sites.

Attaching the Extender TOA converts the 150 into and f/11.68 planetary instrument capable of very high magnification images. It maintains the color correction and flattens the field.

 

 

 

 

pinwheel galaxy m101 takahashi ota refractor ccd imaging astrophotography toa-150b

 

What is refractor without amazing astrophotography qualities? The TOA-130 apochromatic ota not only excellent for visual use, but also for photographic use, specifically in CCD imaging. Planetary observing is to die for in this scope! The slowish f/7.3 focal ratio with a focal length of 1100mm allows for high magnification which can bring out magnficient planetary detail in objects like the moon. If the observor wants to increase their magnification even more while retaining optical quality, the Extender TOA is just what they want! With this optional accessory, the observor can transform this telescope from a f/7.3 to an f/11.68, allowing substantial high magnification!

A 4" focuser is supplied with the Takahashi TOA ota that allows full 360 turns of a CCD camera for flexibility when taking images. It also adds on 225mm backfocus to increase usage of optional accessories like filter wheels
