Double Stack: Every SolarMax telescope comes equipped with double stack technology, featuring two etalon filters arranged in series. This configuration reduces the half width of the light passing through the H-alpha line to less than 0.5 Angstroms. Without double stack, the half width remains below 0.7 Angstroms. You can find the half width specified in the product name and technical details of the telescope.

High-resolution sub-angstrom H-alpha systems have traditionally remained financially out of reach for amateur enthusiasts. Non-Coronado designs often pose challenges due to temperature and F-Ratio requirements. Enter the PST: not only does it boast an impressive bandpass of <1.0 Angstrom, but it also ensures thermal stability, requiring no more effort to operate than inserting an eyepiece and adjusting focus.

The blocking filter stands as the pivotal second element in any Coronado H-alpha system, pivotal not only for your safety but also for the system's performance, akin in importance to the front element. It is essential to note that the blocking filter cannot function autonomously; it requires a Solarmax H-alpha front cell for operation.

Observing the Sun is always a delightful experience, not limited to solar eclipses alone. The dynamic nature of sunspots, constantly changing in number, shape, and size, offers an engaging spectacle. With sufficient magnification, one can even discern the core and boundary areas of a sunspot—the umbra and penumbra. However, it's crucial to ensure that sunlight is reduced to under 1/100,000 of its normal brightness for safe observation.

Astrozap Filters Sun filter for outside diameters from 105mm to 111mm
202.41 €
Tax included
These solar filters ensure safe observation of the Sun with full aperture coverage, sometimes referred to as clear aperture. This design maximizes light intake into the telescope by allowing the complete aperture to be visible, enabling optimal daytime viewing under minimal atmospheric turbulence. In the presence of turbulence, a mask can be applied over the filter's end to effectively reduce the aperture.
