NEW PRODUCT SHOWCASE
 SOLAR WEDGE
Baader Planetarium now offers a Herschel Wedge for solar observing. The Baader
2″ Cool-Ceramic Safety Herschel Prism Mark II ($589) uses a prism to divert a small
percentage of sunlight to the eyepiece. Multiple, staggered light traps made of heatabsorbing
ceramics disperse the diverted solar energy while remaining safe to the touch
after hours of use. The wedge fits in your refractor's 2-inch diagonal and secures your
eyepieces with a patented ClickLock® eyepiece holder. Its rear ceramic heat diffuser
doubles as a convenient solar filter - placing the Sun in its center will also center it in
the eyepiece. The wedge includes a filter holder positioned below the eyepiece with an
adjustment arm for use with variable-polarizing filters (not included). The wedge comes
with a 2-inch, 7.5-nanometer Solar Continuum filter centered on 540 nanometers and a
2-inch neutral density 3.0 filter.

 PLANETARY CAMERA
Chinese manufacturer ZWO adds a new camera for planetary imaging and autoguiding.
The ASI715MC ($199) is a high-speed video camera designed around a Sony IMX715
CMOS detector, which has a 3,840 × 2,192 array of 1.45-micron-square pixels. The small
pixels in this 8.4-megapixel camera achieve a spatial resolution of less than 1 arcsecond
per pixel when paired with optics having a focal length of just 300 millimeters (12 inches).
The camera can record up to 45.1 frames per second in 10-bit, high-speed mode, and
an internal, 256-megabyte DDR3 image buffer ensures no frames are dropped during
downloads. Its body includes a T-thread (M42 × 0.75 mm) interface requiring 12.5 mm
of back focus. The ASI715MC also functions as an autoguider and connects to your
telescope mount via an ST-4-compatible guide port. Each purchase includes a 2-meter
USB 3.0 cable, a 2-meter guiding cable, and a T- to-1¼-inch nosepiece adapter.

 COMA-FREE REDUCER
Meade Instruments now offers a newly redesigned focal reducer for its Advanced Coma
Free (ACF) telescopes. The Meade 0.68× ACF Focal Reducer ($329.99) threads directly
to the rear cell of all Meade ACF telescopes and shortens the focal length of your f/8 or
f/10 ACF telescope to speed up its photographic performance, allowing you to record
great images in less time. Its reduction converts an f/10 ACF to f/6.8, and f/8 models are
shortened to f/5.5. The four-element reducer fully illuminates a 22-mm image circle, and
up to 28 mm with slight vignetting. Its back-focus distance is 105 mm measured from
the reducer's flange, permitting plenty of space for filter wheels and other accessories
positioned within the optical train. The reducer includes a 50-mm-long T-thread adapter
that places DSLR cameras at the correct back-focus spacing.
