Tuning SolarMax II Filter with RichView Tuning System
- After the SolarMax II filter system is fully installed on
the telescope, pointed at the Sun and focused, adjust the the tilt of the external Etalon on the front of the telescope
with the Tmax thumb wheel to achieve the brightest image while eliminating any reflections.
Finally, adjust the
RichView tuning ring on the external Etalon to get the most detail and contrast for the feature you are viewing.
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 filters can be double stacked by adding an additional
SolarMax II Etalon with TMax of the same aperture. Contact your Coronado dealer or Meade Instruments directly
for pricing.
Eyepieces
- The best eyepieces for solar viewing are Coronado’s CEMAX™ contrast enhanced series eyepieces.
Conventional night time eyepieces can also be used, the fewer elements in the optical system the better the view
- try to use 1.25” eyepieces with 2 to 4 elements at the most to reduce spurious light.
Dark Cloth
- One easy way to reduce incidental light from entering your eye is to use a dark cloth to completely
cover your head and the eyepiece. The inside should be black but a reflective surface on the outside is
recommended to avoid heat build up.
Location
- One of the benefits of owning a Coronado solar observing set up is the portability of the system. For
optimal seeing avoid setting up on heat reflective surfaces such as concrete or tarmac. Grass, water, or low trees
are your best surroundings for viewing.
WARNING
Do not insert your eyepiece into the blocking filter until you have the telescope securely mounted and the
SolarMax II element attached and secured.
