AIRY APO80 PHOTO refractor with field flattener

Product code: AIRYAPO80PHOTO

Quick Overview

Many spectacular objects of the Universe that we can photograph have large apparent size in the sky. Therefore, to record the best pictures, you need to have an instrument with a very wide flat field. This allows you to use cameras equipped with large sensors (like the modern DSLRs), obtaining also pinpoint stars to the edges of the image's field.

Our AIRY APO80 PHOTO apochromatic refractor offers, at a special price, all the technical features required for photographing the Universe: flat field also with sensors bigger than the APS-C size (approximately 23x16mm), perfect color correction thanks to FPL-53 lens, Hybrid-Drive high capacity focuser, exceptional PLUS support rings made with CNC machines and aluminum tube. Telescope collimation and optics test included in the price!


Availability: In stock


AIRY APO80 PHOTO apochromatic refractor, 80mm diameter, 500mm focal lenght (f6.25), FLP-53 apochromatic doublet, aluminum tube with 50,8mm Hybrid-Drive focuser with 1:11 fine focus, PLUS support rings (it also comes with photographic tripod adapter), 1x field flattener, AXIS adapter, transport hard case.


AIRY APO80 PHOTO apochromatic refractore offer all the AIRY APO80 technical specifications and it adds:

Dedicated 1x field flattener with AXIS adapter

When you want to take pictures to wide field objects, we suggest to use cameras (such as cooled CCD or DSLR cameras) with large sensors. For example, to record the Pleiades (M45) with AIRY APO80 PHOTO (at 500mm focal length) we recommend a sensor with at least 20mm diagonal.

However, using these sensors, you must pay attention to field curvature, an optical effect that leads to the image distortion towards the edges of the field. For this reason we provide our AIRY telescope with the 1x dedicated field flattener and AXIS adapter: this instrument, directly threaded to the focuser before the camera, perfectly flatten the field even with large sensors (such as the APS-C size DSLR cameras that have approximately 23x16mm dimensions) allowing you to record perfect pictures! All without flexures thanks to AXIS adapter.

The 1x field flattener has, on camera side, a T2 thread (42x0,75 male) to connect CCD or DSLR cameras (the latter, with the T2 ring). This field flattener, to work at its best, needs you to place the camera's sensor at 55mm from the field flattener rear thread. For the DSLR, this distance is obtained adding, beetween the camera and the field flattener, a T2 ring. For CCD cameras, you need to use the right T2 extension rings to perfectly set this distance. If you don't know how to set it, you can contact us and we'll advice you with the best solution. Inside the AXIS adapter, you can also find a M48 thread to connect 50,8mm filters: in this way you can simply add a filter, for example for the light pollution reduction.

PLUS system support rings:

Forget about the uncomfortable and weak support rings that are often found in cheap telescopes! Our AIRY APO80 PHOTO apochromatic refractor comes standard with beautiful aluminum anodized support rings, made with high precision CNC machines, which are part of the PLUS (Prima Luce Universal System) system. This gives you maximum freedom in adapting the telescope to your request; at the same time, it has all the threaded holes, holes and slots suitable for connecting all the PLUS compatible elements, always with simple M6 screws.

For example, you can choose to install either a Losmandy or Vixen plate type, or you can use the holes in the upper part of the rings to install a telescope in parallel (through the guide rings PLUS compatible) or another dovetail plat equals to one located below the telescope (to position where you want guide rings or to allow the sliding Vixen + Losmandy dovetail clamp).

4 years extended warranty and Q-certified controls

All our AIRY apochromatic refractors are equipped with extended warranty, 4 years (instead of 2 of the most telescopes)! This way you will be sure not only to have a great product but also with quality that lasts over time! Each telescope is identified by a unique serial number which is also listed in the manual provided with the package. But our innovation doesn't end there.

In fact we have developed Q-certified, a comprehensive control system that we work out in our laboratory prior to shipment and delivery of the product you ordered. In fact, before delivering the AIRY APO80 PHOTO telescope, we test the collimation and the perfect functioning of all mechanical components.

In addition, we pay much attention and care to shipping, carrying a sturdy packaging and giving it to the courier service. We want to be sure that you will receive your new AIRY APO80 PHOTO not only in the shortest possible time but also with utmost care.

  1. ottimo e versatile review by Nicholas De Zotti on 8/29/15

    Uno strumento fantastico. La cosa che mi piace di più oltre alla qualità delle immagini prodotte è il focheggiatore: veramente preciso e incredibilmente robusto che da solo ne è valso l'acquisto. L'80mm è anche perfetto da utilizzare come cannocchiale su treppiede fotografico e ancora meglio lo uso con estrema soddisfazione come teleobiettivo sulla Canon APS-C (800mm di grane rispetto). Non credo esistano molti tubi ottici con 3 usi in 1 e a questo prezzo meravigliosamente competitivo. Consigliato a tutti

  2. AIRY APO80 review by Francesco on 8/29/15

    Ottimo strumento. Ho cominciato da poco a cimentarmi nell'astrofotografia ma apprezzo molto le doti di questo strumento che anche per chi come me ha poca esperienza risulta di immediato utilizzo senza difficoltà e riserva grandi soddisfazioni. La focale di 500mm consente di gestire facilmente un campo inquadrato grande in cui è difficile perdersi; apprezzo molto il focheggiatore hybrid drive per la sua robustezza e stabilità anche collegandoci un treno ottico "pesante". Una volta bloccata la vite di lock il fuoco rimane perfetto per tutta la sessione fotografica. La possibilità inoltre di poter ruotare il blocco del focheggiatore senza ovviamente dover ripetere la messa a fuoco consente di aggiustare l'orientamento dell'inquadratura fotografica rendendola ottimale anche quando in partenza non dovesse essere stata effettuata con precisione. Uno strumento validissimo, semplice da usare, che consente l'accesso alla fotografia astronomica in maniera essenziale con risultati eccezionali.
