Telescope TS PHOTOLINE APO 130 Triplet f/6.6

TelescopeTS PHOTOLINE Triplet APO 130/860mm with RPA 3" rack and pinion focuser - Triplet APO FPL-53 O'Hara Lens FPL-53

Telescopes TS PHOTOLINE hat-trick APO they offer high quality images reaching levels of performance that until now were only available with much more expensive equipment. Chromatic aberrations have been virtually extinguished, achieving much better color correction than that offered by doublet refractors ED standards. Undoubtedly, the telescopes TS PHOTOLINE guarantee high performance ideal for astrophotographers, with the ability to fully illuminate large CCD sensors and with temperature-compensated lens support cells.

The lens is air-spaced and not cemented. This avoids problems arising from thermal variations that frequently occur in triplet lenses that are cemented (physically bonded, in contact).The telescope TS PHOTOLINE 130/860mm can be recommended without reservation to work with CCD's up to 45mm diagonal.

APOCROMATIC Objective:

Multi-treated APO triplet with 130mm diameter lens and 860mm focal length.
The image is free of chromatic aberrations and false colorations. The TS 130mm triplet f/6 is a refractor equipped with one of the best lenses on the market in its class, including an elementFPL-53 O'Hara. The temperature compensated objective cell keeps the lens free of stress even when working below 0ºC. A solid metal tube and the new Photoline 3" RPA focuser make this a highly recommended choice for both the observer and the astrophotographer.

Telescopes TS PHOTOLINE APO are a new generation of refractor telescopes specially designed for deep sky (wide field) astrophotography.

Each telescope is tested on our optical test bench and shipped perfectly collimated.

Advantages and technical characteristics of the telescope TS PHOTOLINE 130mm f/6 Triplet Apochromatic FPL-53 O'Hara:

-- Air-spaced triplet lens with an O'Hara FPL-53 element
-- Fully adjustable, temperature compensated target cell
-- Photoline 2.5" RPA rack and pinion focuser with 10:1 dual reduction and load capacity up to 6Kg, double speed and 360º orientable
-- Direct thread to M68 (Zeiss) for Reducer/Corrector
-- Rigid aluminum tube with internal baffles to avoid internal reflections
-- Aluminum transport box
-- Retractable sunshade (transport length: 660mm)
-- Tube weight: 13 Kg
-- CNC-machined rings with GP type dovetail (Vixen

-- Back focus: 250mm / 190mm / 130mm
-- Maximum recommended magnification: approx. 330 x
-- Theoretical resolution: 0.88"
-- Visual magnitude limit: 12.4

The RPA focuser is an alternative to the Feather Touch focuser from Starlight Instruments with a quality very close to it but for a much more reasonable cost. With a load capacity of up to 6Kg without slipping or flexing.

-- There is no friction transmission so it cannot slip.
-- Typical M82 and M68 outlet thread of Zeiss for threaded fittings.
-- 2" and 1.25" self-centering adapters
-- Focuser travel: 114 mm with scale
-- Free opening: 77 mm with anti-glare treatment
-- Focusing motor available as an option

Photographic use with two focal lengths (optional):

• 645mm focal length (f / 4.97) with reductorRICCARDI OPTIONAL.
• Using the 0.75x Riccardi reducer, focal lengthresultingis 645 mm, so that sensors up to 42 mm in diameter will be fully illuminated.
• The reducers are screwed to the M82 thread of the focuser using the TSM78-M82 adapter. The back focus with M82 is 77.4 mm.

• 860mm focal length (f / 6.6) withcoupler of2.5 " full size
• This coupler illuminates even full size sensors at 100%. The back focus with M69 female thread is 88 mm.
