Lunt Solar Systems 80mm H-Alpha Telescope with Pressure Tuning - Choose Blocking Filter & Focuser
Lunt Solar 80 mm H-Alpha Pressure Tuned Telescope
The LS80THa from Lunt Solar Systems is an 80 mm, unobstructed, pressure-tuned, dedicated Hydrogen-alpha telescope with a bandpass of < 0.7 Angstroms. The excitement of viewing the Sun, our very own Star, through a dedicated solar telescope is sure to provide many hours of visual enjoyment and educational insights.
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 location 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 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.

About Your Drop-Down Choices:
The base model of the LS80THA comes with a 12mm Blocking Filter (B1200) and a Lunt 2" Crayford Style 10:1 Dual Speed Focuser. The B1200 blocking filter provides a ~4.5mm image when used with this solar scope and is a good choice if you are going to be using the scope visually. The Lunt focuser is solid and stable for most any application, has 10:1 dual focus knobs and an etched focusing scale on the draw tube to visually guide you to the best focus quickly. If that sounds good to you, just choose the first option (12mm Blocking Filter with 2" Crayford Focuser) and your price will remain as shown.
If you would like to upgrade to the Starlight Instruments 2" Feather Touch Focuser and/or the B1800 (18mm) Blocking Filter, just pick from the remaining choices in the drop-down. The B1800 is a worthy upgrade if you will be doing photography through the scope or you want a wider field of view visually. A Starlight Feather Touch focuser is always a nice upgrade! Either focuser should perform well but if you plan to ride heavy loads off the focuser then perhaps you should consider the Feather Touch, which can handle up to 5.5 pounds. The price of the telescope package will adjust depending on the blocking filter and focuser you choose.
