Visit LS40THa Standard Kit is a dedicated H-Alpha solar telescope designed to offer detailed observation of the Sun in an ultra-portable format. Weighing in at just 2.6 pounds (approx. 1.2 kg) and featuring 400 mm f/10 optics, it is the ideal instrument for amateur astronomers who want a solution grab-and-go without compromising on image quality.
Equipped with the latest generation of standards, each unit is individually tested with precision metrology equipment to guarantee real, verified performance. The LS40THa offers an exceptional bandwidth of 0.35 Å, enabling it to reveal the finest details of the solar chromosphere.
Thanks to its front-mounted, tilt-adjusted standard, this telescope guarantees a totally unobstructed aperture, with no central obstruction. The result is a sharper, higher-contrast image. By pointing the instrument at the Sun, you gain direct access to the chromosphere, a dynamic layer where the most spectacular solar phenomena occur.
You can observe :
The included 12 mm flat-field eyepiece offers 33x magnification, ideal for detailing fine structures and tracking the evolution of solar phenomena in real time.
The LS40THa Standard Kit has been designed to offer a simple and immediate experience. Right out of the hard case, the user can install the telescope and start observing in a matter of minutes. All components are perfectly compatible and optimized to work together.
The SunLock solar finder enables fast, secure alignment, while the mini helical eyepiece holder ensures precise focusing without image rotation. The Vixen dovetail ensures universal compatibility with most frames.
This model is fully compatible with a double stack system. By adding the LS40FHa filter, the combined bandwidth can be reduced to less than 0.25 Å, further enhancing contrast and the visibility of surface details.
This scalability enables users to upgrade their equipment as their needs change, while maintaining a high-quality optical base.
