The Takahashi FC-100DZ is the latest addition to Tak's Steinheil fluorite doublet refractor line-up. The high quality optics are optimized with a fluorite (CaF2) rear element and a front element made of low dispersion glass with a high refractive index. This combination produces wonderfully color corrected images with a Strehl ratio of 97.6% across the visible spectrum. Attached you will find spot, Strehl, and spherical aberration diagrams to support Takahashi's claims regarding these beautiful optics.
Like other refractors in the Takahashi FC-100 series, the 100DZ is compatible with the FC/FS Multi-Flattener and the FC-35 0.66X Reducer. This f/8 system will reduce to f/5.3 with the addition of said reducer, and provide full illumination to a full-frame sensor.
The FC-100DZ comes with the Takahashi 2.7" Rack & Pinion Focuser. It has a retractable dew shield. When the dew shield is retracted and any accessories are removed from the back end, the 100DZ becomes just 23.4" long, making it an easy scope to take with you to remote viewing sites, solar eclipses, and vacations. The OTA weights a mere 8.5 pounds without accessories.
