The Takahashi FS-152 fluorite doublet refractor is now being made with a
tube that is about 50mm shorter than the tube with which it was previously made. Anyone out there own one of these newer FS-152's? If so, can you tell me whether you can reach focus with all your eyepieces without using an extension tube? Thanks in advance! Bill G. |

Hi Bill, I think all the FS series is getting the 2" shorter tube. The FS102II is available at Anacortes and has a sliding dew shield too. Ed T. |

This sounds like a prayer answered for imagers: usually the Takahashi refractors have so little back focus it is hard to get a CCD camera/ filter wheel and focuser to come to focus. The 2" shorter tube should be about all that is needed to solve that problem. I wonder if they will do that to the FSQ106 too? rdc |
