Product information "LUNT LS2HW 50.8mm (2'') Herschel-wedge"
Herschel-wedge / Solar-wedge for superior White-Light solar observing and imaging. For refractor-telescopes up to 150mm aperture, and with 2'' focuser. Complete system with installed ND3.0 filter.

Herschel-Wedges will be used to observe the sun in White-Light. Around 95 % of the sun light will be suppressed by the Herschel Wedge. The remaining sun light will be dimmed by a fix installed ND3.0 grey filter. Lunt Solar Systems Herschel-wedges are installed in a fully closed housing with integrated heat trap. There is no stray light escaping, therefore it is very safe.

The difference between Herschel-wedges and normal front mounted filters is, that the filtering takes place just before the eyepiece or camera. This will provide a better contrast and sharpness of the solar image.
Furthermore, there is more safety at a Herschel-wedge than at a front mounted filter. A Herschel-wedge can not rip or become holes like a foil. And also it can not drop down from the telescope objective accidentally.

Only for use with refractor telescopes up to 150mm aperture:
Because the full energy and heat of the sun will be inside the telescope, we advise to use only refractors with a Herschel-wedge. The refractor must not have corrector lenses at the back. Optical elements like corrector lenses, or secondary mirrors of reflector telescopes, become very hot by the concentrated solar energy and could be damaged.

Tuning the brightness:
Because the Herschel-wedge produce polarized light, you can use a normal polarizing filter at the eyepiece or camera-adapter. By turning the polarizing filter the brightness will be reduced.
Polarizing filter not included. We recommend the BRESSER 2'' polarizing filter 4946465.

LUNT LS7-21ZE Zoom Eyepiece 7.2mm - 21.5mm
Lunt Solar Systems zoom-eyepiece with variable focal length from 7.2mm to 21.5mm, with 1.25 inch (31.7mm) connection.The special of this zoom eyepiece is that the optical layout offers highest quality views of the sun, but also on nightsky objects. LUNT minimized the reflections by using superb multicoatings and with care designed internal baffle system and blackened lens edges. The LUNT zoom-eyepiece is not the widest field zoom-eyepiece on the market, LUNT prefered best performance over widest field. The sun and stars are perfect pin point across the entire field of view without any visible distortion. The LUNT zoom-eyepiece is almost parfocal, from one end to the other end of the zooming way you need only 0.5mm to refocuse. The LUNT zoom-eyepiece has a very nice height adjustable eyeguard to protect your eye against day light reflections and to help you to find the perfect eye position.Please note that these eyepieces are only accessories for existing solar telescopes or filters when observing the sun. Solar observation alone with these eyepieces without additional solar filters is not possible!FEATURESFocal length: 7.2mm - 21.5mm continuously adjustableBarrel size: 1.25 inch (31,7mm)Diameter: 47mmHeight: 82mmWeight: 170gEye relief: 15mmLenses / Groups: 7 lenses / 4 GroupsField of view: 53° at 7.2mm - 40° at 21.5mmSCOPE OF DELIVERYLUNT Zoom Eyepiece 7.2mm - 21.5mm

This provides better contrast and sharpness of the solar image - with more surface detail visible as a result.  Furthermore, a Herschel wedge is inherently safer than at a front mounted filter.
