Solar filter holder for Sky-Watcher Sun 150mm refractor
Want to observe the Sun safely with your Sky-Watcher 150mm refractor? This holder is exactly what you need. It is a precisely made mounting bracket with a ready-prepared opening where you can easily and securely attach solar filter foil - for example, the popular Baader Astro Solar Folie. This lets you build a fully functional solar filter tailored to your telescope, without any unnecessary compromises.
What is included and how does it work?
The holder is supplied on its own, without a filter. It comes with a pre-cut opening for inserting and fixing the filter foil. The most commonly used option is Baader Astro Solar Folie, available in different optical densities:
| Optical density |
Intended use |
| ND 3.8 |
Visual observation (looking through the eyepiece) |
| ND 5.0 |
Solar photography and astrophotography |
You simply place the foil into the holder and fix it in position using glue or another method of your choice. The finished filter then slides onto the objective end of the telescope tube. The whole design is made so that the filter stays firmly in place and cannot accidentally slip off - which is an absolutely essential safety requirement when observing the Sun.
Precise fit for Sky-Watcher 150mm refractors
The holder is designed specifically for Sky-Watcher refractors with a 150mm objective diameter, ensuring an accurate fit with no play and no need for improvised modifications. For astronomers who want to observe sunspots, planetary transits across the solar disk, or the changing activity of the photosphere, this accessory provides a reliable foundation for the entire observation setup.
Who is this holder for?
This holder is ideal for owners of Sky-Watcher 150mm refractor telescopes who want to build a quality solar filter themselves - whether for budget reasons or because they want full control over the foil used and the overall quality of the filter. It is suitable for:
- Beginners who are just discovering the world of solar observation
- Experienced observers who know exactly what they are looking for
- Anyone who wants a safe, custom-built solar filter for their telescope
Solar astronomy is a fascinating subject that can be enjoyed during the day, and with the right filter and a quality refractor it offers a surprisingly rich observing programme throughout the whole year.
Complete your solar filter setup
If you are looking for a complete solution, remember to also purchase Baader Astro Solar Folie in the appropriate optical density for your purpose - ND 3.8 for visual observation through the eyepiece, or ND 5.0 for astrophotography of the solar disk.
