Easily portable and a joy to use, the Lunt 50 mm joins the Lunt Telescope lineup as our smallest aperture offering, while providing the power, amazing detail and quality you expect from a Lunt Telescope — all at an impressive ~4.0 mm solar image size!
Description
This is a 50 mm, unobstructed, pressure-tuned, dedicated Hydrogen-alpha telescope with a bandpass of <0.7 Å. The excitement of viewing our star through a dedicated solar telescope is sure to provide many many hours of visual enjoyment and educational insights.
Furthermore, this package is fully upgradeable at any time without ever having to go back to the factory. Therefore, as the Sun becomes increasingly more active, you will appreciate that the instrument can grow right along with it.
