of 6562.8 Angstroms, you will need to adjust the tuning slightly
to get the best high-contrast views of the features you want to
observe. After the SolarMax II telescope is pointed at the Sun and
the image has been focused, move the RichView tuning lever up
or down slowly while looking at the image in the eyepiece to get
the most detail and contrast. Surface details will generally require
one setting, while prominences will require a different setting for
maximum detail.
Tuning SolarMax II Double Stack 60 with RichView Tuning
System - With a double stack system, follow this procedure for
best results: After the SolarMax II telescope is pointed at the Sun
and the image has been focused, move the RichView tuning lever
on the telescope up or down slowly while looking at the image in
the eyepiece to get the most detail and contrast. Now adjust the
tilt of the external Etalon on the front of the telescope with the
TMax wheel to achieve the brightest image while eliminating any
refl ections. Finally, adjust the RichView tuning ring on the external
Etalon to get the most detail and contrast for the feature you are
viewing. Because double stacked systems operate at a very
narrow band pass of only 0.5 Angstroms or less, more tuning is
needed for different areas and features on the Sun.
Double Stacking - This greatly increases contrast by narrowing
the bandpass to <0.5Å and gives a spectacular 3D effect showing
increased surface detail. The SolarMax II 60 telescope can be
double stacked by adding an additional SolarMax II Etalon with
TMax (Product #SME60). Contact your Coronado dealer or Meade
Instruments directly for pricing.
Blocking Filters - The SolarMax II 60 telescope is available with a
BF5, BF10 or BF15. All are in the form of a diagonal with eyepiece
holder. You MUST use the Coronado diagonal that contains the
blocking fi lter. You cannot substitute another diagonal for the
Coronado Blocking Filter Diagonal. This would create an unfi ltered
system and deliver light from the Sun that will cause damage to the
eye. Contact Coronado if you are unsure which version you have.
Imaging & Bino-Viewers - All SolarMax II series telescope will
allow for both prime focus and eyepiece projection imaging with
standard equipment. For prime focus imaging it is recommended
that you thread the optical element of the CEMAX 2x Barlow to the
draw tube of the blocking fi lter. being sure to replace the blocking
fi lter into the draw tube once completed. Bino-Viewers will also
come to focus using a Barlow or optical correcting system. There
are many cameras that can be used for imaging - Coronado does
not make adaptors.
