NEW PRODUCT SHOWCASE
PREMIUM TRIPLET
Airy Disk, a relative newcomer to the industry, unveils its line of premium
apochromatic refractors. The smallest in the series is the Pro APO AP 85/510
Triplet ED FCD-100 ($999). It's an 85-mm (31/3
-inch) f/6 triplet apochromat
with a FCD-100 super-low-dispersion element. The telescope weighs 3.4
kilograms (7½ pounds) and features a 2½-inch-format, 10:1 dual-speed
focuser that includes both 2-inch and 1¼-inch eyepiece adapters fitted
with non-marring compression rings. The scope accepts the optional 0.92×
Full-Frame Reducer / Flattener 85 mm - 140 mm ($250), which produces a
corrected field large enough to accommodate APS-C-sized detectors. Each
purchase includes a pair of mounting rings, a Vixen-style dovetail bar, a universal
finder mounting bracket, and an aluminum lens cap.

 STRAIN-WAVE MOUNT
Sky-Watcher USA adds a new model to its line of equatorial telescope
mounts. The Wave 100i ($1,695) is a Go To mount designed to take advantage
of the high-torque capabilities of strain-wave gearing. The mount features fast
drives in each axis, allowing slewing and tracking speeds of 10° per second.
The mount head weighs 4.3 kg and can bear an instrument load of 10 kg and
up to 15 kg with an optional counterweight kit ($110). The mount operates
in both equatorial and alt-azimuth modes. Its dual-format saddle accepts
both Losmandy-D and Vixen-style dovetail mounting bars. The Wave 100i is
controlled with Sky-Watcher's upgradable SynScan Go To hand paddle, which
includes a database of more than 42,000 objects, and its built-in Wi-Fi allows
control using Sky-Watcher's SynScan app for Android and iOS devices. A 12volt,
2-amp power supply is required.

Starfield Optics now offers a compact astrograph for mobile astrophotographers.
The Starfield Gear60Q (CAN $1,165.14) is a 4-element, 60-mm f/5

to produce sharp, color-free stars across a 44-mm fully corrected image circle.
The telescope weighs 2 kg and features a 2½-inch-format, dual-speed,
rack-and-pinion focuser with rotator and tilt adapter. A reduction adapter is
included with 48-mm threads to attach your camera, and it accepts 2-inch
photographic filters. Also included are a Vixen-style mounting bar, a quickrelease
