adjust the tuning slightly to get the best high-contrast views
of the features you want to observe. After the SolarMax III
telescope is pointed at the Sun and the image has been
focused, rotate the RichView™ tuning ring slowly while
looking at the image in the eyepiece to get the most detail
and contrast. Then, adjust the tilt of the etalon with the
T-Max tuner wheel to achieve the brightest image while
eliminating any reflections. Surface details will generally
require one setting, while prominences will require a
different setting for maximum detail.
Double Stacking
A second etalon for a Double Stack system will show
increased contrast by narrowing the bandpass to <0.5Å and
provides a spectacular 3D effect showing increased surface
detail. The SolarMax III 70 telescope can be double stacked
by adding an additional SolarMax III external etalon. Contact
your Coronado dealer or Meade Instruments directly for
pricing.
Tuning SolarMax® III Double Stack 70 with RichView™
Tuning System
Start out with both T-Max™ Tuners in the closed position.
This is achieved by turning each T-Max™ tuner adjustment
wheel clockwise until the gap of the tuner is at a minimum.
Also to start, adjust the RichView™ tuner so it is turned
counter-clockwise against its hard stop. This is the ideal
starting point for the SolarMax® III 70 Double Stack
telescope.
After the SolarMax® III telescope is pointed at the Sun
and the image has been focused, rotate the T-Max™ tuner
located closest to the Sun in the clockwise direction.
On page 11, this is labeled as the First T-Max Tuner. Only
adjust the tilt of this tuner until any internal reflections
are positioned off the image of the Sun and in the least
bothersome position. With low magnification eyepieces, it
may be difficult to remove the internal reflections completely
from the field of view.
When adjusting the tilt on the T-max tuner, keep in mind
the least amount of tilt used is best as image quality will
begin to suffer with excessive tilt. You only need to adjust
the internal reflections to the point where they do not bother
your view.
Next, slowly adjust the RichView™ Tuner clockwise until the
best contrast is achieved.
Finally, adjust the T-Max™ tuner closest to the eyepiece. On
page 11, this is labeled as the Second T-Max™ tuner. Only
adjust the tilt of this tuner until the best contrast is achieved
and the H-
α
views you want to see are visible. Keep in mind
the least amount of tilt on the T-Max™ tuner used is best.
After these adjustments, you may find it beneficial to go
back and re-adjust the RichView™ tuner again to make sure
you are seeing the best detail possible.
