Double-stack filter for LS40THa telescopes.
The bandwidth of H-alpha systems can be reduced by so-called "double-stacking". A smaller bandwidth provides much more contrast at the solar surface, thereby many more details will become visible.
Double-stacking with a bandwidth of only <0.55 Angstrom is also possible at the LS40THa telescopes. Therefore Lunt Solar Systems has especially designed this LS40FHa double-stack filter in compact housing.
FEATURES
Aperture: 40 mm
Bandwidth: <0.55 Angstrom
Tuning: mechanical tilt-tuning
Housing diameter: 70mm
Length: 60mm
Weight: 0,3kg
only usable together with a LS40THa telescope!

Instruction manual
The 10x eyepiece is suitable for all microscopes with 23.2mm eyepiece tube diameter. This diameter is widely used in stereo microscopes, also from other brands or manufacturers. Please select the eyepiece magnification in correspondence to the objective you are using. A low objective magnification allows for a higher magnification of the eyepiece. For example, combined with 4x or 10x objectives, eyepieces with 20x or 25x magnification can be used without loss of image quality. With a 100x objective, a 10x or 12.5x eyepiece is usually the highest recommended eyepiece magnification.
To calculate the maximum useful magnification, consider the numerical aperture (N. A.) of the objective lens:
numerical aperture of the objective lens x 1000 = max. useful magnification
Here is a typical example: for a 10x objective with numerical aperture NA 0.25, a maximum of 250x magnification can be realized. This is realized with a 25x eyepiece. The numerical aperture is usually printed besides the magnification factor on many objectives.
Magnifications beyond the max. useful magnification do not show any further details (so-called “empty magnification”) and are therefore not recommended.
