Coronado SolarMax III Solar Telescope

The double-stacked etalon system narrows the bandwidth of light passing through the telescope to less than 0.5 Angstroms. This significantly increases contrast, allowing you to see finer details in the solar chromosphere, such as active regions and filaments, that would be washed out in a single-stack system.

Yes. By removing the external solar etalon filters, the SolarMax III functions as a standard 70mm achromatic refractor. This makes it a versatile tool for observing the Moon, planets, and brighter deep-sky objects when you aren't tracking the sun.

It is highly recommended. Solar features can be subtle, and the two-speed rack and pinion focuser allows for the fine, precise adjustments needed to snap those features into sharp focus, especially when you are switching between visual observation and imaging.

The 2-inch rack and pinion focuser is compatible with most standard astronomy cameras. You will likely need a T-adapter specific to your camera model to connect it to the focuser, but the system is robust enough to handle the weight of most dedicated solar imaging setups.

The included Sol Ranger finder is designed specifically for solar use, making alignment straightforward and safe. It projects a small image of the sun onto a translucent screen, so you never have to look directly at the sun to center it in your eyepiece.

While it includes mounting rings, it does not come with a tripod or mount. Because solar observation requires precise tracking to keep the sun centered, a sturdy alt-azimuth or equatorial mount is recommended to ensure a stable and comfortable viewing experience.
