Lunt 50mm H-alpha Solar Telescope with B600 Blocking Filter and Pressure-Tuner

The Lunt 50mm H-alpha Solar Telescope from Lunt Solar Systems is a 50mm, unobstructed, pressure-tuned, dedicated Hydrogen-alpha telescope with a bandpass of <0.75 Angstroms.

True Doppler Tuning (Pressure Tuning) allows for a shift into and away from the user, adding a 3D-like component to the viewing experience. While it has minimal effect on proms due to their being at the edge of the disk, it does have an effect on filaments and active regions on the surface. While looking at a filament at the center of the Sun the user has the ability to Doppler shift from the base of the filament to the tip, following the filament through it’s structure toward you and away from you, allowing for enhanced visual and imaging capability for the observer as well as a research tool for the avid hobbyist. The pressure tuning system provides an order of magnitude more precision to the tuning of the desired features.

This version of the Lunt 50mm H-alpha Solar Telescope features the B600 blocking filter, the largest fitted to the 50 series making it ideal for solar imaging. H-alpha solar imaging is best done with a mono planetary camera. See the recomended items below.
