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, 50,8mm OnAxisLock adapter, photographic
tripod connection (mounts support rings available), rigid transport bag.
The AIRY ED72 apochromatic refractor offers all this along with other first-class features:
FPL-51 72mm apochromatic lens
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).
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
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: closing it, you will be sure
that your camera will not move any more! 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
45Â° erect image prism for the one of terrestrial objects (use as a
OnAxisLock 50,8mm adapter
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 ED72's focuser has the new
OnAxisLock locking device 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
Precision mechanical construction and 360Â° quality
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
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:
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.
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).
A complete line of dedicated accessories:
Our complete line of accessories for AIRY let you personalize your telescope according to your needs. Always with quality and operating certificated instruments!
4 years extended warranty and Q-certified controls
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.
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
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.
every AIRY telescope is identified by a unique serial number. Right:
functional and collimation verification of optics on optical bench.

Sir George Biddell Airy
George Biddell Airy (27 July 1801 â€“ 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.
