PREMIUM APO
REFRACTOR
Explore Scientific ♦
explorescientificusa.com
From the tip of its carbon-fiber
dew shield to the back of its
massive 3-inch HEX focuser, the
165mm FPL-53 Apochromatic
Refractor is packed with features
for discriminating observers. The
165-mm (6½-inch) f/7 air-spaced,
three-element objective promises
outstanding performance. It
comes with tube rings and a
Losmandy-style dovetail plate,
2-inch star diagonal, and a hardsided transport case.

U.S. price: $9,999.99

VERSATILE ASTRONOMY
CAMERA
MallinCam ♦ mallincam.net
What most caught our attention about
the MallinCam SkyRaider DC10c is
the manufacturer's comments about
it being designed with the Celestron
RASA astrographs in mind (see
page 28). This one-shot color CMOS
camera with a high-sensitivity, backilluminated Sony sensor is packed
with features, including an on-the-fly
stacking algorithm that automatically
aligns images made with telescopes
operating in altazimuth-tracking mode.

U.S. price: $929.99

BIG DOB TO GO
Hubble Optics ♦
hubbleoptics.com
Large-aperture, portable
Dobsonian telescopes are not
unusual, but a 24-inch f/3.3
that weighs only 154 pounds
(70 kg) and has a maximum
eyepiece height of 77 inches
off the ground is certainly,
well, different! But those are
the specs for the UL24 from
Hubble Optics. Furthermore,
the scope breaks down into
pieces that easily fit in most
compact vehicles for transport.

U.S. price: $9,500

STAND ALONE DEEP-SKY
SMARTCAMERAS
Astrel Instruments ♦
astrel-instruments.com
A new line of high-performance
astronomical CCD cameras from the
Italian firm Astrel Instruments does away
with the need for external computers
to capture and process deep-sky
images. The camera's built-in WiFi link,
1000 MHz processor (for operating the
camera and processing images), and
up to 64 Gb of storage are controlled
by a remote desktop app on any
network-connected device, including
smartphones, tablets, and PCs.

U.S. price: from 1,600€
(about $1,850)
