Gondwana Telescopes 12-inch

Marana Compact Dobsonian


Hailing from Australia, Gondwana Telescopes makes ultralight Dobsonians
designed to maximize portability. Like other Gondwana scopes, the 12-inch
f/5 Marana uses mirrors made by Sky-Watcher. Customers can supply their
own optics, if desired, for a $1,000 discount. The Marana is constructed from
finished marine-grade plywood for a sturdy feel and an attractive look. Ebony
Star and Tef lon bearing materials promise smooth sailing across the sky.
Standard accessories include a red-dot finder, carbon-fiber truss poles, high-
resolution magnetic encoders on both axes, and a customized KineOptics
HC-2 focuser with 1¼" adapter. When stowed, the Marana’s components
break down and nest together to make everything as compact as possible, an
important factor if you have big-scope dreams but small-world limitations.

Hubble Optics 24"

f/3.3 Premium Ultra Light


Dobsonian Telescope


Hubble Optics’ UL16 16-inch Dobsonian
was recognized as a Star Product in 2012.
It’s back this year with an even bigger aper-
ture, the 24-inch f/3.3 UL24, whose compact-
ness and weight set it apart from much of the
competition. The telescope’s open truss design,
“sandwich” mirror, and all-metal components
cut the total weight to 154 pounds (70 kg).
Everything disassembles and fits together so
neatly that this huge instrument can fit into a
compact car. Once the scope is assembled, the fast f/3.3 focal ratio keeps the
eyepiece height to only 77 inches (1.96 meters) when pointed at the zenith.
The UL24 includes 96 percent enhanced coatings on both the primary and
secondary mirrors, and features a dual-speed 2" Crayford-style focuser.

Great American Eclipse


21st-century eclipse map


The August 2017 Great American Eclipse whetted


many an appetite for total solar eclipses. To answer


the questions of when and where to see the next,


Michael Zeiler has created this poster showing the


paths of every total solar eclipse crossing North


America this century, from August 2017 to September



  1. Each path gives the eclipse date, maximum


duration of totality, and maximum eclipse-path


width. Measuring 22 by 28 inches (56 by 71 cm),


the map is printed on glossy card stock and shipped


rolled in a tube for framing.
