Product description

In short:

  • Large refracting telescope with 155mm aperture
  • First-class colour correction thanks to FPL55 triplet lens
  • Multi-coating on every glass-to-air surface
  • Internal screens to prevent scattered light
  • 3.7" R&P focuser with M63 and M92 connection

The TS Optics AP 155/1240 is amongst the largest refracting telescopes on the market. An exceptional refracting telescope which can provide a lifetime’s worth of joy and will enhance any observatory!

  • The apochromatic triplet lens with an FPL55 element and additional Lanthanium special glass displays pinsharp stars and bright planets without colour fringing.
  • Multi-coating on every glass-to-air surface for maximum transmission, internal screens within the lens tube prevent scattered light
  • The improved lens mount keeps its alignment perfectly featuring traction and pressure screws.
  • Despite its large aperture, the apochromat is relatively lightweight and can be mounted on a Skywatcher EQ-6 or iOptron GEM45, for example.
  • Every apochromat comess with a manufacturer’s test certificate. The apochromat is given a serial number. Furthermore, every apochromat is tested on the optical bench and optimally collimated.

3.7” rack and pinion focuser: The large focuser is optimised for photography and carries loads up to 8 kg - fully sufficient for heavy cameras with accessories! There are also multiple internal threads available for screw-on adaptations, in particular for the recommended flattener. The focuser also rotates by 360° in order to select the correct field of view.

Astrophotography: The apochromat can be paired with all suitable correctors. We recommend the ]: This corrector screws directly onto the focuser’s M92 thread. The corrector provides illumination and correction up to an image circle diameter of 60 mm. The focal length remains unaltered.
