(SOLD)Takahashi FS-128 fluorite APO optical tube.F/8.1 , efl 1040mm. Just received my Tak 6" APO, so I'm selling this magnificent 5-incher. Purchased new from ASTRONOMICS in March 2003. Pristine condition. Performs and looks as new. Fabulous optics that provide incredible, razor-sharp, ultra-high-contrast views of Mars, Jupe, and Saturn. Pinpoint star images and marvelous resolution. Complete with 6x30 Tak finder, Parallax tube mounting rings, 1.25" and 2" visual backs, 2.7" focuser, original packaging and documentation. Original cost: $4967 + shipping. Will sell for $3975 + shipping ( no mount or star diagonal included) or complete with new Celestron CG-5 Advanced Series EQ mount with heavy stainless steel tripod legs and RA drive ( 3-second damping time and quite adequate for visual astronomy)for $4300. Will ship OTA alone, but prefer local pick-up or "halfway" meeting with the mount(Buffalo, NY, area). No trades, please.
