LUNT anti-reflex filter for LS100THa / DSII

HRG100DS anti-reflex filter for LS100THa / DSII systems, effectively reduces reflections.

With the LS100THa H-alpha solar telescopes double-stacking is possible with the internal DSII double-stack modules. The DSII modules reduce the half width to <0.5 Angstrom. The DSII modules are designed to better show the surface details of the sun, significantly increasing contrast and making filaments and active regions more visible.

But the DSII modules also cause reflections, which are noticeable as strong brightening around the sun. This so-called "glow" is no problem when observing the sun's surface. But it can complicate the observation of protuberances, and many observers find it disturbing.

The anti-reflex filter HRG100DS for the LS100THa serves to solve this problem. The filter effectively reduces the reflections.

The HRG100DS is easy to install. It is not necessary to return the telescope to the manufacturer, the filter can be easily installed by the user.

This filter can not be used individually! It can only be used on a Lunt Solar Systems LS100THa Solar Telescope together with a DSII Double-Stack Module.
