Optics

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.

Introducing the Baader AstroSolar Safety Film, renowned as the world's finest solar filter material, now available in a comprehensive range of premium mounted Baader Solar Filters. Engineered with cutting-edge design and construction, these filters are tailored to fit an extensive array of instruments, from telescopes to spotting scopes, camera lenses, and binoculars.

Experience the pinnacle of solar observation with EclipSmart solar products, featuring cutting-edge ISO-certified Solar Safe filter technology. These filters provide comprehensive protection against harmful solar radiation, including infrared (IR) and ultraviolet (UV) light, while blocking an impressive 99.999% of visible light. 

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.

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.

Double Stack: Each SolarMax telescope is equipped with double stack technology, featuring two etalon filters aligned 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.

Observing the sun in H-Alpha is an exhilarating experience with the compact SolarMax III telescopes! Equipped with the integrated ‘True’ Etalon filter, these telescopes offer superior contrast and sharper images compared to models with smaller filters.

Energy Rejection Filters are designed to reduce the heat load on your filter assembly by either absorbing or reflecting UV and/or IR light while transmitting light within the desired visual spectrum. These filters typically come in Red or Yellow glass variants, or as dielectric IR and UV filters, ensuring that light in the desired visual spectrum is passed through.

Connection (to the telescope): 1.25"

Introducing the Daystar Quark Gemini, a revolutionary tool that combines both Prominence and Chromosphere bandpass filters, allowing instant switching between the two views. With this innovative device, observers can seamlessly transition between broad-stroked prominences and high-contrast narrow bandpass views without the need for equipment swapping or refocusing.

Magnesium is a notably magnetized element present on the sun, known for its high temperatures during energetic activity. Spectroscopically, the Zeeman effect manifests as a "splitting" of the line, where dark absorption occurs slightly above and below the typical wavelength of non-magnetized activity, notably at 5172Å.

Observing and imaging the Sun in Sodium-D2 at 589 nm unveils intricate details within sunspots and the photosphere, surpassing those visible in white light.

Quality Achromat Doublet: This 60mm refractor boasts a high-quality doublet lens, delivering superior contrast and resolution for both visual observation and imaging.

This top-tier solar filter ensures safe observation and photography of the sun. Easily slip it onto telescopes, spotting scopes, cameras, or any optical device. Featuring Helios Solar Glass®, it boasts a Neutral Density 5 rating, effectively blocking 99.999% of all light, including harmful IR and UV rays.

These thin film solar filters offer safe full aperture viewing, allowing maximum light transmission through your telescope. Optimal daytime viewing is achieved with the full aperture, especially when atmospheric turbulence is minimal. Constructed from durable .002” thick black poly plastic, the optical thin film ensures longevity with proper care and regular use, comparable to off-axis solar filters and full aperture glass solar filters.

Mount Material: Aluminium

These full aperture Solar Filters offer safe glass solar filtering, maximizing light transmission through the telescope for optimal viewing. They enable clear observation of the telescope's full aperture, ensuring the best possible daytime viewing with minimal atmospheric turbulence. In cases of instability, applying a mask over the filter's end effectively reduces the aperture.
