NEW PRODUCT SHOWCASE
4-INCH APOCHROMAT
Stellarvue adds a new model to its extensive line of SVX
apochromatic refractors. The SVX102D ($2,195) is a 102mm
(4-inch) f/7 doublet apochromat that pairs a superlow-dispersion
element with a rare-earth lanthanum element
to produce sharp, color-free views. The tube weighs
roughly 4 kilograms (9 pounds) and measures 54½ centimeters
(21½ inches) long with its dew shield retracted, 67
cm fully extended. The SVX102D comes with a 3-inch-format,
dual-speed focuser and includes both 2- and 1¼-inch
eyepiece adapters with non-marring compression rings.
Purchasers can upgrade the focuser to a Starlight Instruments
3-inch Feather Touch Focuser at additional cost.
Each scope purchase comes with an aluminum lens cap,
a pair of CNC-machined mounting rings, and a dovetail
finder mounting base.

COMA CORRECTOR
Orion Telescopes & Binoculars now offers a dual-use
field corrector for its Newtonian telescopes. The Orion 2″
Photo-Visual Coma Corrector for Newtonians ($129.99)
corrects coma and field-curvature aberrations inherent
in fast Newtonian reflectors, resulting in pinpoint stars
in wide-field eyepieces and cameras alike. Designed to
correct reflectors with focal ratios between f/3.5 and f/6,
the unit fits into 2-inch focusers and adds a mild 1.1×
magnification factor to your optical system. The corrector
performs best with about 75 mm of backfocus. Its 2-inch
eyepiece holder is replaced with the included M48-to-Tthread
adapter for imaging. An additional 20-mm spacer
ring is required for optimal performance with DSLR cameras,
and other spacers are needed for use with mirrorless
or astronomical cameras.

 COMPACT GUIDER
iOptron expands its imaging support with an autoguiding package for
most small- to mid-sized tracking mounts. The iGuider Autoguider
System ($218) pairs the company's iGuider Mini Guiding Scope with
its iGuider 1 Camera to produce excellent guiding accuracy for shortto
medium-focal-length imaging systems. The iGuide Scope includes
a 30-mm f/4 achromat that mates with iOptron's CEM26, GEM28,
CEM40, and GEM45 mounts and can be used on other telescopes with
standard finderscope dovetail saddles. The iGuider 1 Camera is built
around a 1.2-megapixel CMOS detector with 3.75-micron-square pixels
in a 1,280 × 960 array, resulting in a resolution of 6.44 arcseconds per
pixel. The iGuider supports pulse guiding and comes with a 2-meter
USB 2.0 cable to connect with your control computer.
