Lunt Solar 60mm Ha Solar Telescope with Pressure Tuner / B600 Filter / 2" Crayford Focuser

The excitement of viewing our Sun through a dedicated solar telescope is sure to provide many hours of visual enjoyment and educational insights. This package is fully upgradeable at any time without ever having to go back to the factory. As the Sun becomes increasingly more active, you will appreciate that the instrument can grow right along with it.

Lunt LS60THa solar telescopes with a pressure tuner provides the basic essentials perfect for a first time introduction to Daytime Solar Observing, while also including the newest technology for fine tuning, allowing basic research of the Sun's disk and some surface details.

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 prominences due to them 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 its structure, 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.

Package Features:

• Narrow Band Hydrogen-alpha (656.28nm) Dedicated System.
• A refractor based system with a 60mm front objective.
