Solar Observations with the Baader Safety Herschel Wedge

Binoviewing is especially impressive when you look at the sun – you'll see it in 3D, like 
a ball floating in space. Delicate surface details will be much more obvious compared 
to monocular viewing. The MaxBright

®

 II Binoviewer is uniquely suited to provide 

outstanding views with the 2" Baader Herschel Solar Prism, an optical accessory de-
signed for refractor telescopes to permit safe, high-resolution observation and imaging 
of the solar photosphere. As the Herschel Solar Prism does not have T-2 threads on 
the top, a T-2/2" adapter ring 

# 1508035

 is required. Inserting the binoviewer into the 

2" eyepiece holder is not recommended as it may not be possible to reach focus on 
many refractors due to the long optical path length of the various components. 

CAUTION:

 Before you start exploring the Sun it is very important to be informed about 

all the possible risks of solar observation. Please take a careful look at the manuals of 
all the equipment and filters before pointing your telescope at the Sun.

unscrew the clamp. Then you can access a female 2"-SC-thread, into which you can 
screw the 2"-SC/T-2-adapter 

# 1508035

. The glasspath corrector is inserted into the 

2"-SC/T-2-adapter.
Now you can attach the MaxBright

®

 II either directly to the prism with the T-2 counter 

nut, or you attach the optional TQC quickchanger 

# 2456313A

 to the housing, to use 

the Zeiss microbayonet.
