Binorum SolidSun Genesis 76/700 solar filter kit
Want to enjoy a view of our nearest star without compromising on safety or image quality? The Binorum SolidSun Genesis 76/700 kit is exactly what you are looking for. Designed exclusively for the Binorum Genesis 76/700 AZ2 telescope, this kit lets you assemble your own solar filter that protects your eyesight while revealing fascinating details of the solar surface.
Premium Baader AstroSolar Visual film - the gold standard in solar observation
The key element of the kit is the premium Baader Planetarium AstroSolar Visual film, which is recognized worldwide among astronomers as the gold standard for solar observation. The film has an optical density of ND=5.0, meaning it transmits only 0.00001 of incoming light - just the fraction needed to make observation completely safe even during prolonged viewing sessions.
The resulting image of the Sun has a neutral white color that faithfully corresponds to reality, making it easier to distinguish fine surface structures such as granulation, sunspots, and faculae.
Optical quality unaffected by film thickness
The film thickness of just 12 micrometers is a deliberate design choice. Minor creasing or slight wrinkling of the material has no negative effect on optical quality. The film therefore maintains exceptional sharpness and contrast even at high magnifications, without needing to be kept in a perfectly flat state.
What can you see through this filter?
The practical performance of the filter is truly impressive. Already at 60x magnification, the first details become visible on the solar disk:
- Fine granulation of the photosphere - the cellular structure caused by convection of hot plasma
- Complex sunspot structures with their dark core (umbra) and transition region (penumbra)
- Brighter areas known as faculae
Every observer, from beginner to experienced amateur astronomer, will appreciate just how much can be seen with this filter.
Kit contents and assembly
The kit includes:
- A mounting ring precisely matched to the tube diameter of the Binorum Genesis 76/700 AZ2 telescope
- Baader AstroSolar Visual film
The two components are joined using a universal adhesive. It is important to ensure that the adhesive does not come into contact with the optical surface of the film, so as to preserve its full transparency and functionality.
About the Binorum brand
Binorum is a brand created by astronomers for astronomers. The entire philosophy of the brand rests on a simple principle: to offer observers of the night and daytime sky products that truly work, are designed with real user needs in mind, and maintain a high standard of quality.
The Binorum SolidSun solar filter is a prime example of this approach - a precisely sized mounting ring, proven Baader film, and clear assembly instructions. Binorum also offers a wide range of astronomy accessories, so your Genesis 76/700 AZ2 telescope can be gradually expanded with additional components from the same ecosystem.
