Takahashi TOA130S
Takahashi TOA130 is the newest line of refractor in Takahashi's telescope. It features a newly designed triplet objective. This new design is absolutely color free. TOA130 is not only an outstanding optical instrument, but it can be used to make outstanding images with a CCD or DSLR. So, I use this telescope to take images with my STL11000 camera.
My favorite picture taken with this scope is Andromeda Galaxy an d Horsehead Nebula.
