Coronado SolarMax III Solar Telescope

The RichView tuning system allows you to physically tilt the etalon filter to adjust the bandpass. This fine-tuning is essential for shifting the contrast to better see specific solar features, such as prominences on the edge of the sun or surface granulation.

No, this is a dedicated solar telescope. The internal hydrogen-alpha filters are specifically designed to isolate the light emitted by the sun and will not provide useful views of stars, planets, or the moon at night.

Yes, the 90mm aperture is quite capable for solar imaging. It provides enough light-gathering power and resolution to capture fine details in solar surface structures that smaller solar scopes might miss.

Yes, the SolarMax III is a complete system. It includes the necessary blocking filter and etalon, which are critical for safe solar observation, so you do not need to purchase additional solar filters to view the sun safely.

The 15mm blocking filter is sized to provide a clear, unvignetted field of view for most standard eyepieces and imaging sensors. It is an important component that ensures the image remains sharp and high-contrast across the entire frame.
