Apertura now offers a high-quality, 6-inch astrograph. The Apertura CarbonStar 150
Imaging Newtonian with 0.95× Coma Corrector ($999.95) is a 5.9-inch f/4 reflector
designed for astrophotography with crop-sensor cameras. The carbon-fiber optical
tube is 50.8 centimeters (20 inches) long and weighs just 4.7 kilograms (10.4 lbs). Its
dual-speed, 2-inch linear bearing focuser can hold heavy cameras and additional accessories
and accepts most third-party automation motors. The included 0.95× Coma
Corrector produces a fully corrected image circle of 28 mm. Both primary and secondary
Borosilicate mirrors feature enhanced aluminum coatings with a SiO2 overcoat
boasting 96% reflectivity. Each scope also comes with CNC-machined aluminum tube
rings, both Vixen-style and Losmandy-D-style dovetail mounting bars, a 2- to-1¼-inch

TINY OBSERVING STATION
Chinese manufacturer ZWO announces its newest entry into the " Smart Telescope "
market with the Seestar S30 ($349). The device is built around two lenses: a 30-mm f/5
apochromatic triplet refractor, and a wide-angle lens. The larger optic is paired with a
Sony IMX662 CMOS color camera having a 1,920 × 1,080 array of 2.9-micron-square
pixels, while the wide-angle lens is paired with a smaller sensor. The telephoto lens
includes bult-in, selectable filters to combat light pollution and enhance nebulosity. The
optics and internal electronics ride along in a compact alt-azimuth Go To mount that
weighs 1.65 kilograms (3.6 pounds). The Seestar S30 is controlled with a smartphone
or tablet using the ASIAIR app and connects with either Wi-Fi or Bluetooth. Images are
saved on 64GB of internal memory. The device is powered by an internal, rechargeable
lithium-ion battery that can run the device for up to six hours. Each purchase includes
a field tripod, USB-C charging cable, a solar filter, and a carrying case.
