The Lunt 50mm comes complete with the basic essentials and is equipped with pressure tuning technology; lauded as the newest and ultimate technology for fine tuning, the pressure tuning allows beginners and professionals alike to delve into and research the Sun’s disk and surface details.

Doppler Tuning

True Doppler Tuning (Pressure Tuning) allows for a shift into and away from the user. Amazingly, this adds a 3D-like component to the viewing experience. Meanwhile 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. Also, when 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. Therefore, you’ll be able to follow the filament through it’s structure toward you and away from you.  All of this allows for enhanced visual and imaging capability for the observer as well as a research tool for the avid hobbyist. Most importantly, the pressure tuning system provides an order of magnitude more precision to the tuning of the desired features.
