PREMIUM BINOCULARS

Astro-Physics astro-physics.com

There are countless binoculars on the market,
but only two models carry the Astro-Physics
name. According to company founder
Roland Christen, these 11×70 and 16×70
binoculars offer a flatter field, are sharper at
the edges, and have reduced color fringing
compared with the previous versions deemed
excellent enough to be in the company's product lineup. Made with individual-focus eyepieces
and full-illumination BAK4 porro prisms, the 11× model
has a 4.8° field of view and the 16× a 4.1° field.

ONE-ARM ROBOTIC MOUNT
PlaneWave planewave.com

Built to operate in either altazimuth or equatorial mode,
PlaneWave's new L-500 Direct Drive Mount is rated for
telescope loads up to 200 pounds. The single-arm design
has dovetail connections on both axes, making it extremely
easy to balance loads regardless of their size and shape.
High-resolution encoders on both axes provide precise
pointing with slewing speeds up to 50° per second. Optional hardware allows mounting telescopes on both sides
of the fork arm simultaneously.
* U.S. price: $18,000

DIGITAL DETECTOR
Sony Semiconductor sony-semicon.co.jp

In 2015 Nikon grabbed the attention of astrophotographers
with the introduction of its 36-megapixel, astronomyfriendly D810A DSLR (reviewed by Jerry Lodriguss in the
February 2016 issue, page 56). The full-frame, color CMOS
detector at the heart of that camera - Sony's IMX-094AQP
- is now working its way into cooled astronomical cameras made by ZWO and QHY. This is good news for those
wanting the features and improved imaging performance
offered by a cooled astronomical camera. Will other camera
manufacturers follow? Time will tell.
* U.S. price: camera from $3,999

MOBILE IMAGING
ZWO astronomy-imaging-camera.com

Digital astronomy is increasingly mobile these days with
apps taking on the tasks that were once possible only with
desktop and laptop computers. ZWO's free ASIcap app
for Android devices (running OS 4.4 and up) has achieved
a mobile milestone by offering total operation of ZWO
ASI USB 3.0 cameras with just the mobile device (some
devices require an external power source). It's no longer
necessary to cart along a computer to take and store
images and videos with these cameras, thus lightening the
load for astroimagers.
* U.S. price: free
