Primaluce Lab AIRY ED72 72mm f/6 Apochromatic Doublet Refractor Telescope

AIRY ED72 apochromatic refractor, 72mm diameter, 430mm focal length (f6), FLP-51 apochromatic doublet, aluminum tube with 50,8mm Hybrid-Drive focuser with fine focus knob, photographic tripod connection (mounts support rings available), rigid transport bag.

High-performance optics, highest level mechanics and great price all in a compact, lightweight and portable product that can be used both as travel telescope (even on photographic tripod) or as wide field astrophotography apochromatic telescope. Our comprehensive range of accessories allows you to customize it to suit your needs!

The AIRY ED72 apochromatic refractor offers all this along with other first-class features:

FPL-51 72mm apochromatic lens

The AIRY ED72 apochromatic refractor uses a doublet lens with FPL-51 element fully multi-coated that offers superior correction of chromatic aberration, compared to the classic achromatic refractor, but at a lower price than the FPL-53 models. For this reason, the AIRY ED72 apochromatic refractor is perfect for those customers looking for a  large diameter instrument but at an affordable price, very good for long-exposure astrophotography. It's also perfect for those who use monochrome CCD cameras with narrow-band filters for color images (the use of such filters cancels the small residual chromatic aberration and makes perfect the final image).

The short focal length (430mm) and the fast focal ratio (6) make it perfect for wide field astrophotography of many extended objects, which will be shown in their full extent also with cameras equipped with not too large sensors (and therefore not too expensive).

In order to maximize the quality of this apochromatic refractor using cameras with more than 15mm diagonal sensors (such as DSLRs), it can be used with the optional 1x 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 ED72 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: tighten it and you can be sure that your camera will stay where it should be!

The 50.8mm Hybrid-Drive focuser presents the connection for 50.8mm and 31.8mm accessories (comes with a handy 31.8mm reducer). 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).

Precision mechanical construction and 360° quality

You will be amazed of the mechanical quality of our AIRY ED72: 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 87mm PLUS system support rings. The AIRY ED72 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 ED72 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 plat equals to one located below the telescope (to position where you want guide rings or to allow the sliding Vixen + Losmandy dovetail clamp).

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.
