NEXDOME OBSERVATORY
Canadian Telescopes nexdome.com

Made of durable, ultraviolet-protected ABS plastic, the
8-foot-diameter NexDome can be assembled in a few
hours by one person using common hand tools. The shutter extends 100°, allowing telescopes to point to the zenith.
NexDome is available as the dome only, or with a variety of
base assemblies and a rotation motor, including ones with
up to five external storage bays.
* Priced from $1,699

QHY183C CAMERA
QHYCCD qhyccd.com

This new entry from QHYCCD piqued our interest because
of its 20-megapixel Sony IMX183 color sensor. The highsensitivity, back-illuminated CMOS detector has very small
2.4-micron pixels, making it a good match for short-focallength telescopes. Two-stage thermoelectric cooling, a
128-megabyte internal memory buffer, and USB 3.0 connectivity for fast download times (up to 15 full-resolution
frames per second) round out an impressive list for features
available in a camera costing less than $1,000.
* U.S. price: $949

TAKAHASHI FSQ-130ED

Texas Nautical Repair
takahashiamerica.com
Following in the footsteps of Takahashi's legendary FSQ106 astrograph, the larger-aperture FSQ-130ED is a 130mm f/5 five-element, flat-field telescope, which delivers
razor-sharp stars across an imaging circle 110 mm across.
Three of the lens elements are made from extra-low dispersion (ED) glass for superb color correction, and the scope's
5-inch focuser is designed to handle heavy cameras and
accessories. Look for our field tests of the FSQ-130ED in
the coming months.
* U.S. price: $13,150

OPTIMUS EYEPIECES
Stellarvue stellarvue.com

Stellarvue's new line of ultra-wide-field eyepieces with
15 mm of eye relief is well matched to the company's
high-quality, short-focus telescopes. The 3.6- and 4.7-mm
eyepieces offer extraordinarily wide 110° apparent fields
of view, while the 9- and 20-mm models have 100° fields.
Except for the 20-mm, which has a 2-inch barrel, the eyepieces fit 1¼-inch focusers and each comes with a custom
2-inch adapter threaded for 2-inch filters. All lens elements
are fully multi-coated and have blackened edges to reduce
scattered light and improve image contrast.
* U.S. price: $399 each
