TEC APO180FL Flagship

Notes: This is the Telescope Engineering Company (TEC) APO180FL f/7 Fluorite, it is the flagship of my astrophotography. It is a 7” 180mm giant with a native focal length of 1260mm and a theoretical resolution of 0.66 arc sec, and is sitting atop the Astro-Physics 1200 GTOCP4 mount. I use this scope in two configurations, One, is using the Astro-Physics 160TCC (Telecompressor Corrector) This changes the f/ ratio from f/7 to f/5.23 941mm. The other configuration is using the Astro-Physics 160FF (Field-Flattener) This changes the f/ ratio from f/7 to f/7.36, 1325mm. I consider this to be one of the best scopes of it’s size made today.
