Quick Overview

AIRY BLACK 80T apochromatic refractor, 80mm diameter, 500mm focal length (f6.25), FPL-53 apochromatic triplet, carbon tube with 2" Hybrid-Drive focuser with fine focus knob and 50.8mm OnAxisLock adapter, PLUS support rings, transport hard case.


A great refractor for those searching for a great quality lens with the best mechanics, all in one product yet compact, lightweight and highly portable. Thanks to the optional "Deluxe 2.5" field flattener for 80T" that can be directly screwed on the focuser of the telescope (to prevent flexures), this telescope offers an incredible flat field for sensors up to FullFrame (24x36mm )! Telescope collimation and optics test included in the price!

AIRY BLACK 80T refractorAIRY BLACK 80T apochromatic refractor, 80mm diameter, 500mm focal length (f6.25), FPL-53 apochromatic triplet, carbon tube with 2" Hybrid-Drive focuser with fine focus knob and 50.8mm OnAxisLock adapter, PLUS support rings, transport hard case.

The AIRY BLACK 80T apochromatic refractor offers all this along with other first-class features: 

  

AIRY BLACK 80T refractor



80mm FPL-53 apochromatic triplet

The AIRY BLACK 80T apochromatic refractor uses a triplet objective with FPL-53 lens that, thanks to the perfect chromatic aberration correction, generate detailed and rich in contrast images. It's the perfect instrument for long exposure deep-sky astrophotography of weak objects like galaxies, nebulae and star clusters.

Who wants to use large sensors cameras (such as DSLR cameras) can use the optional 2" field flattener for AIRY BLACK for camera with sensors up to APS-C (diagonal up to 27mm) or the 2.5" Deluxe field flattener for AIRY BLACK for camera with sensors up to FullFrame (diagonal up to 44mm) to get a great flat field corrected for large sensors!

Giant Hybrid-Drive 2" focuser

One of the strengths of the AIRY BLACK 80T refractor is its wonderful Hybrid-Drive 2" focuser. The mechanical building precision eliminates the typical problem of normal Crayford focusers that, during the long exposures required by astrophotography, can have camera slippage moving the sensor out of focus. For this reason we have chosen to provide our AIRY BLACK 80T telescopes with the Hybrid-Drive 2" focuser that adds, under the focuser tube, a rack and pinion thereby maintaining in position even heavy cameras (capacity of up 3 Kg). Below the focuser there's also a locking screw: closing it, you will be sure that your camera will not move any more!

The Hybrid-Drive 2" focuser presents the connection for 50.8mm accessories (in the picture, with the 31.8mm OnAxisLock optional adapter). It also features a convenient 1:10 fine focus gear, particularly useful when you need to focus at high magnification.

The focuser has a very long ride (80mm) to allow the use of both photographic instruments (cameras with accessories) and visual (eyepieces and mirror diagonals). For visual use, we recommend our 50.8mm XP dielectric diagonal for the observation of the sky or our XP 45° erect image prism for the one of terrestrial objects (use as a spotting scope).

1x 2" field flattener up to APS-C or 2,5" Deluxe field flattener up to FullFrame (optional)

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. AIRY BLACK 80T has 2 optional field flatteners: 

- 2" field flattener for AIRY BLACK that flattens the field for sensors up to FullFrame (diagonal around 27mm)

- 2,5" Deluxe field flattener for AIRY BLACK that flattens the field for sensors up to FullFrame (diagonal around 44mm)

Connected to the focuser before the camera, the field flattener corrects field curvature allowing you to get perfect point shaped stars in the entire sensor. Both field flatteners, in order to have best performances, needs you to place the camera's sensor at 55mm from the field flattener rear thread.

 

 

 

OnAxisLock 50,8mm locking device

Using heavy photographic accessories such as DSLR or cooled CCD (often with filter wheels) cameras, it is crucial to avoid flexions when we insert them into the telescope's focuser. This also applies also to visual use when we connect large diagonal and wide field eyepieces (which are often very heavy).

For this reason, the AIRY BLACK 80T's focuser has the new OnAxisLock locking device on 50,8mm connection instead of normal thumbscrews. This allows you to perfectly lock the inserted accessory by rotating the outer (red) ring: a special inner ring tightens accessories with a uniform pressure.

The OnAxisLock device also helps keep perfectly aligned on axis the accessories inserted into the focuser: you'll be so sure that the camera's sensor will be perfectly centered in the telescope optical axis.

Precision mechanical construction and 360° quality

You will be amazed of the mechanical quality of our AIRY BLACK 80T: full carbon tube to offer maximum lightness and rigidity. In addition, the carbon optical tube is thermally more stable than aluminum: therefore when the outside environmental temperature changes, the AIRY BLACK 80T allows you to better keep the focus point during long exposures required for astrophotography!

The carbon front dew shield can be closed to make the telescope more transportable. The front cap is completely aluminum made. The focuser can be rotated freely through 360 degrees (without changing the focus point) to position the camera with the right angle and perfectly frame the object you want to record. The AIRY BLACK 80T refractor is an optics and mechanics jewel, and to carry it or keep it protected at best, it comes with a beautiful aluminum hard case.

PLUS system support rings:

Forget about the uncomfortable and weak support rings that are often found in cheap telescopes! Our AIRY BLACK 80T apochromatic refractor has 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! 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 BLACK 80T 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 BLACK 80T not only in the shortest possible time but also with utmost care.

Sir George Biddell Airy

Sir George Biddell Airy (27 July 1801 – 2 January 1892) was an English mathematician and astronomer, Astronomer Royal from 1835 to 1881. His many achievements include work on planetary orbits, measuring the mean density of the Earth, a method of solution of two-dimensional problems in solid mechanics and, in his role as Astronomer Royal, establishing Greenwich as the location of the prime meridian.
