Re: Takahashi, TEC, or Astro-Physics ?

I'm preparing to purchase a high grade 6-inch refractor for visual and
photographic work.

How does Takahashi, TEC, and Astro-Physics refractors of this size
compare?

Are there any reviews around that look into a comparison between those
brands?

Any other comments are welcome.


The specs will tell you nearly all there is to say about the differences
between these scopes. The optical accuracy is for all practical purposes
equal. The TOA 150 is said to have extraordinary color correction but it
may be the slowest of the three to reach thermal equilibrium because of the
optical configuration I assume you're considering the AP 160 and TEC
140/160 along with the TOA?
