With the Photoline APO series, Teleskop-Service stands for non-compromised optical and mechanical quality.

This 130mm f/7 triplet Apo refractor is equipped with one of the best lenses in its class, including a proven Ohara FPL53 element. The temperature compensated cell keeps the lenses free of stress even at temperatures below 0 °C. A solid metal tube and the new Photoline 2.5" RPA focuser recommend this telescope for the demanding observer and astro photographer.

Main characteristics:

  • Air spaced 130mm triplet lens with Ohara FPL53 element
  • 910 mm focal length, f/7
  • Multicoating on every glass air surface
  • Temperature compensated and fully adjustable cell
  • 2.5" RPA Photoline rack & pinion focuser with 1:10 dual speed transmission - up to approx. 5 kg payload
  • Direct M63 thread for reducer/corrector
  • Stiff aluminium tube with internal baffles
  • Retractable dew cap

The new Photoline RPA 2.5" deluxe focuser:

This focuser is an alternative to the Starlight Instruments Feathertouch focuser - with a quality close to it, but for a reasonable price. It holds accessories up to approx. 5 kg without tilting or slipping.

  • No transmisstion by friction that may slip
  • M63x1 thread for further adaptations
  • 2" and 1.25" self-centering accessory adapters

The Lens:

We decided deliberately for the high-quality version with FPL53 element. The multi coated lenses are mounted in a temperature compensated cell, the edges of the air-spaced elements are blackened.

TS 2.5" full-frame size corrector and field flattener TSFlat2.5
