Solar filter holder for Sky-Watcher Sun 90mm MAK
Would you like to safely observe the sun with your Sky-Watcher Maksutov-Cassegrain 90mm telescope? This holder is exactly what you need. It is a practical filter-free bracket, designed specifically to let you easily and securely mount solar filter film - for example the popular Baader Astro Solar foil - and then safely attach the whole assembly to the front lens of your telescope.
How it works
The holder comes with a precisely prepared opening for mounting filter film or another compatible solar filter. This means you can make or fit the filter yourself - simply cut the right piece of Baader foil, insert it into the holder and secure it in place. The result is a firm, safe and easy-to-attach assembly that fits directly onto the front objective of the MAK 90mm tube.
This solution is especially useful when you do not want to invest in a complete ready-made filter, but prefer a flexible approach with your own foil, which offers excellent optical performance even at higher magnifications.
Compatibility
The Sky-Watcher MAK 90mm solar filter holder is compatible with a wide range of MAK 90/1250 tube models that Sky-Watcher offers in various mount configurations. If you already own this telescope and have not yet been able to observe sunspots, planetary transits or partial solar eclipses, this holder opens the door to the fascinating world of solar astronomy.
Safety information
Looking directly at the sun without proper filtration is extremely dangerous and can cause permanent eye damage. Using certified Baader Astro Solar foil together with this holder provides sufficient reduction of light intensity and also protects against heat radiation.
Always check the following before observing:
- The filter is firmly secured before you begin observing
- The foil is not damaged in any way
- There are no holes or folds in the foil - any such defect is a reason to replace the foil immediately
Summary
Overall, this is a simple but very useful accessory for any owner of a Sky-Watcher MAK 90mm who wants to extend their observing possibilities into solar astronomy. The investment is minimal, but the benefit is significant - especially if you plan to add a white light filter for the photosphere or an H-alpha accessory for the chromosphere in the future.
