Daystar Sol 100mm Dedicated Hydrogen Alpha Solar Telescope

The Daystar Sol 100mm is a clean-sheet, dedicated Hydrogen Alpha solar telescope engineered as an integrated system rather than a standard telescope with a filter added on.

Its optical train is optimized around the 656nm Hydrogen Alpha wavelength, delivering a full-disk field of view with 100mm of aperture while keeping the instrument compact and outreach-safe.
