TEC APO 200 FL f/8 Fluorite Apochromat
The APO 200 FL is an observatory class instrument with excellent color correction thanks to glass combined with Fluorite as a middle element.
The advantages of Fluriot to ED glass: less adsorption or rather more transmission
APO 160 FL Apochromat vs. APO 140 EDThe TEC APO 200 FL has number of features that in a given combination are rarely found in one scope:
- Precision apochromatic objective with modern coating that makes lenses almost invisible
- Retractable Dew Shield
- Light weight tube assembly. Theobjective is housed in an aluminum cell, providing for excellent thermoregulation properties while remaining lightweight and strong.
- The optical assembly sits in a lightweight aluminum tube that utilizes anti-reflective coating and sharp-edged baffles throughout the interior and forget about collimation – after the scope leaves TEC, no adjustment is required.
- Each APO200FL F/8 comes equipped with a Starlight Instruments FTF#3545 Feather Touch Focuser that was designed in collaboration with TEC. This is Starlight Instruments’ largest rotating focuser with coarse and fine focusing 9:1 Planetary Reduction Assembly
- The 2” locking metal collet is insensitive to temperature fluctuations and holds loads with high precision and concentricity
- Able to accommodate a wide variety of eyepieces
- Recommended to be paired with a high capacity load mount and a stationary observation station
