  • Teleskop Service ED apochromat with 125 mm aperture f/7.8 with perfect chromatic correction and photographic 2.5" R&P focuser.

    This apochromatic refractor is equipped with one the best objectives of its class. The moderate focal ratio and the use of two special glasses (FPL53 and lanthanum glass) allows for a correction which is clearly above the level of two-lens ED apos in this price range. The image quality is comparable with three-element lenses. The telescope can be used visually without any restrictions and, thanks to the optional field flattener and focal reducer, there is also no obstacle to astrophotography.

    Advantages and Features

    • Air-spaced dublet objective with no relevant chromatic aberration - special glasses FPL53 (from Ohara) and lanthanum glass.
    • Temperature compensated, fully adjustable cell made of metal.
    • 2.5" RPA Photoline dual-speed rack and pinion - holds accessories up to 5 kg
    • Direct M63 thread connection for correctors and reducers with sufficient working distance
    • Stable aluminium tube with internal baffles
    • CNC tube rings with GP/EQ5 style dovetail bar
    • Weight: 7.57 kg - so also small mounts like the EQ5 or Celestron Advanced VX can carry the Apo.
