Optical power, mechanical quality and design features at the highest levels, all in a compact and easy to transport product: our AIRY APO80 apochromatic refractor offers all of this at an unbelievably low price! Thanks to its extraordinary lens with FPL-53 element, it offers a perfect chromatic aberration correction for images with no false color and very high contrast. Thanks to the short focal length (500mm), it can be used in astrophotography even with compact equatorial mounts (eg type HEQ5). In addition, the compact and lightweight body makes it a perfect instrument even for travel.

The AIRY APO80 is an apochromatic refractor with 80mm diameter, 500mm focal length (f6.25), FLP-53 apochromatic doublet optics, aluminum tube with 50,8mm Hybrid-Drive focuser with fine focus knob, 50.8mm OnAxisLock adapter, photographic tripod connection (mounts support rings available) and comes supplied in a rigid transport bag.

The AIRY APO80 apochromatic refractor offers all this along with other first-class features:



FPL-53 80mm apochromatic lens, perfect colors

The apochromatic refractor AIRY APO80 uses as lens a doublet with FPL-53 lens fully multi-coated for a perfect chromatic aberration correction generating images with no false color, high contrast and rich in detail. This feature is perfect for long exposure astrophotography with color cameras (like DSLR), where the color aberration ruins photographs in not perfectly corrected telescopes. 

The short focal length (500mm) and the fast focal ratio (6.25) make it ideal for shooting wide field extended objects such as the Andromeda Galaxy (M31), the Orion Nebula (M42), or the Veil Nebula (NGC6992) that will be shown in their full extent also with cameras equipped with not too big sensors (and not too expensive).

In order to maximize the quality of this apochromatic refractor using cameras with more than 15mm diagonal sensors (such as DSLRs), we recommend the use of field flattener which makes pinpoint stars up to image edges.

50.8mm Hybrid-Drive focuser

Often refractors are provided with Crayford focusers suitable for visual use but not for photo applications. In fact, during the long exposures required by astrophotography, this type of focuser can cause camera slippage moving the sensor out of focus. For this reason we have chosen to provide our Airy APO80 telescopes with the new 50.8mm Hybrid-Drive focuser that adds, under the focuser tube, a rack and pinion thereby maintaining in position even heavy cameras (capacity of up 8 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 50.8mm Hybrid-Drive focuser presents the connection for 50.8mm accessories (a 31.8mm reducer is optional). It also features a convenient 1:11 fine focus gear, particularly useful when you need to focus at high magnification. The focuser has a very long ride (95mm) to allow the use of both photographic instruments (cameras with accessories) and visual (eyepieces and 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).

This new version of the AIRY APO80 now comes with a self centering 2" ON AXIS LOCK that serves as a eyepiece holder that offers a greater clamping force, avoiding any possible flexure (so it's perfect for astrophotography). It does not damage the connected accessory and perfectly centers the optical axis of the telescope. All this thanks to this new double-ring locking device: just rotate manually the appropriate outer ring (designed to allow an easy grip, even with gloves) in order to obtain a perfect locking!

Precision mechanical construction and 360° quality

You will be amazed of the mechanical quality of our AIRY APO80: full aluminum intubation made with precision CNC machine is rugged yet lightweight. All the components are treated at the highest levels to provide an instrument with which is a real pleasure to photograph or watch the sky! The aluminum 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.

Below the optical tube there's a metal plate which allows installation on photographic tripods (perfect for use as a terrestrial spotting scope). This plate has the shape of a Vixen dovetail bar then the telescope can also be installed directly on mounts with this connection. For long exposure astrophotography use we suggest our 90mm PLUS system support rings. The AIRY APO80 refractor is an optics and mechanics jewel, and to carry it or keep it protected at best, it comes with a beautiful hard case.

PLUS system support rings (OPTIONAL):

Forget about the uncomfortable and weak support rings that are often found in cheap telescopes! Our AIRY APO80 apochromatic refractor can be used (optional) 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 plate equals to one located below the telescope (to position where you want guide rings or to allow the sliding Vixen + Losmandy dovetail clamp).

The security of your purchase: Q-certified

We often hear users are not sure about purchasing: is the telescope collimated? Has the operation been verified? Does the focuser work?

For this reason, 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 ED72 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 ED72 not only in the shortest possible time but also with utmost care.
