The SolarMax II 60 Double Stack Telescope from Coronado features the RichView tuning method which allows direct adjustment of the primary etalon filter. With RichView, the scope can be tuned for more precise wavelengths of light of the hydrogen-alpha (Ha) band. This allows for higher contrast views of active regions, flares, filaments and other surface features. It can be quickly re-tuned for prominences on the solar limb.

The SolarMax II 60 Double Stack is a dedicated H-Alpha solar viewing telescope with a 60mm SolarMax filter, a T-Max 60 tuner, a BF-5 blocking filter, and a CEMAX 25mm eyepiece. The 60mm aperture is double stacked with one internal etalon filter and one external etalon filter at a bandwidth of <0.5 Å. The double stacked SolarMax II filter system delivers superb contrast and detailed resolution. By combining two SolarMax II filters, fine-tuned individually with the RichView tuning system, the bandwidth is reduced from <0.7Å to <0.5Å. The effect of the narrower bandpass is greatly increased contrast on the surface of the Sun, bringing out details in active regions, filaments, flares and other surface phenomenon. The telescope can be used without the external etalon filter attached thereby increasing the bandwidth to <0.7 Å.

The heart of the SolarMax II 60 Double Stack's viewing system is the SolarMax 60 filter and it's matching T-Max 60 Doppler Tuning Unit. This combination can be selectively adjusted by the viewer to de-tune the telescope's optical system. The wavelengths produced by high-velocity events such as active flares and coronal mass ejections (CME) can Doppler-shift and become invisible to a fixed H-Alpha system. The slight adjustment range made possible by the T-Max 60 allows these phenomena to become more visible.

All SolarMax filters must be used with a secondary interference filter. This package includes the BF-5 blocking filter - a 1.25" right-angle diagonal that produces a 4.6mm image. The BF-5 is thermally stable, so the image will not drift off the H-Alpha line as it heats up during use. Its 10mm aperture is matched to the telescope's focal length for full disk views of the Sun. This large aperture also enables the use of most Barlow lenses - this simplifies digital photography and enables the use of binoviewers.

SolarMax telescopes produce outstanding views of the Sun's active surface with 100% safety. None of the parts in this kit are stand-alone units - each component is equally crucial to the user's safety and the system's performance.

Double Stacked
Double stacked filter system delivers superb contrast and detailed resolution at <0.5 Å
RichView Tuning Method
RichView tuning method allows for higher contrast views of active regions, flares, filaments and other surface features
Dedicated H-Alpha Telescope
400 mm f/6.6 solar viewing refractor offers enhanced resolution
BF-5 Blocking Filter
The BF-5 is a 1.25" right angle diagonal that must be used with a SolarMax filter. It produces a 4.6 mm image
SolarMax 60 H-Alpha Filter
60 mm <0.7 Å or <0.5 Å when double stacked for more detailed, higher contrasted solar views
T-Max 60 Doppler Tuning Unit
The T-Max 60 is used to de-tune the SolarMax filter towards the blue end of the H-Alpha line. This enhances detailed observation and imaging of solar disk shapes, surface details, prominences, granulation, and edge activities
CEMAX 25 mm Eyepiece
A high-quality 25 mm ocular for telescopes that accept 1.25" eyepieces. This Plossl eyepiece features sharp optics, a compact form-factor, long eye relief, and a standard apparent field of view
Sol Ranger Finderscope
The Sol Ranger attaches to the SolarMax telescope's clamshell mount. A pinhole on the front of the Sol Ranger allows a harmless beam of light to be projected onto an opaque glass viewer when the sun is in the main scope's FOV. The resulting image can be viewed easily from the rear of the telescope - this ensures a rapid and accurate alignment process

      Comments about Coronado SolarMax II 60 Double Stack Telescope:

      Having the dual stack really helps. I am able to carefully tune and see solar flares, prominences, and sunspots quite well. Also many white areas show very well. I am using my own eyepieces and find a 9 MM eyepice at 44 power works quite well. I am excited over this fine scope.
