Coronado SolarMax III 90 Double Stack Solar Scope with BF15: Unveiling Solar Splendor

The Coronado SolarMax III 90mm refractor stands as the pinnacle of the SolarMax III telescope series, purpose-built for capturing breathtakingly high-resolution details of our celestial neighbor, the Sun. Here’s why this telescope deserves a closer look:

1. Largest Aperture, Compact Design:
   • With its generous 90mm aperture, the SolarMax III 90mm offers unparalleled light-gathering capability.
   • Lightweight and compact, it comes complete with a robust hard-shell carrying case, ensuring you can take this hydrogen-alpha (H-α) telescope anywhere—from your backyard to chasing down solar eclipses worldwide.
2. Crafted in North America:
   • Designed and meticulously manufactured in North America, the SolarMax III 90mm boasts quality and precision.
   • The lens blanks are proudly made in the USA by Meade.
3. Hydrogen-Alpha Magic:
   • At the heart of the SolarMax III 90mm lies the large external front 90mm air-spaced etalon.
   • This etalon allows you to explore the most captivating part of the solar spectrum: Hydrogen-alpha light (6562.8 Angstroms). Here, the Sun reveals its intricate features—the solar disk and its dynamic atmosphere—in stunning detail.
   • The ultra-narrow bandpass of <0.7 Angstroms (Å) ensures exceptional contrast, allowing you to witness prominences erupting from the solar limb and study sunspots, filaments, active flare regions, plages, and surface granulation.
4. Safety First:
   • The 15mm blocking filter (BF15), positioned inside the diagonal holder, ensures safe solar viewing.
   • Multiple internal filters, including the Induced Transmission Filter (ITF), Long Wave Pass filter (LWP), and H-alpha cut-off filter, work harmoniously to provide a fully unvignetted image with the included eyepieces.
   • Compared to the smaller BF10, the BF15 offers an even larger unvignetted area—essential for high-magnification observations and imaging with larger camera sensors.
5. Optical Excellence:
   • The SolarMax III 90mm features an 800mm focal length (f/8.9) refractor doublet lens with a 90mm aperture.
   • Expect a clean, high-contrast image across the entire field of view.
6. Fine-Tuning Precision:
   • Coronado’s patented RichView tuning technology allows you to adjust the distance between the parallel glass plates of the external etalon. This precise tuning optimizes the wavelength bandpass for specific solar features while maintaining optical alignment.
   • The included T-Max Tuner further refines image quality by eliminating reflections and enhancing brightness.
   • Together, RichView and T-Max deliver unparalleled solar detail.
7. Complete Package:
   • The SolarMax III 90mm comes equipped with a backlash-free 2″ dual-speed rack & pinion focuser, offering both coarse and fine focus adjustments (10:1 reduction).
   • The Sol Ranger Solar Finder simplifies aiming at the Sun.
   • Standard optical accessories include 25mm, 18mm, and 12mm CEMAX eyepieces, along with the CEMAX 2x 1.25″ Barlow.
   • An all-new black and silver aluminum hard carry case (Dimensions: 26.5″ x 8.66″ x 8.66″) ensures your investment stays protected.
8. Safety Assurance:
   • Coronado rigorously tests all solar filters and telescopes in specialized labs accredited to verify compliance with the ISO 12312-2 safety specifications for solar viewing.

Experience the Sun like never before with the Coronado SolarMax III 90mm refractor—a gateway to solar marvels! ☀️🔭
