Lunt Solarsystems anti-reflection filter for LS100THa/DSII effectively reduces reflections visible as a strong glow around the sun when using the DSII double-stack module. This allows for higher contrast views of filaments and active regions, especially when observing prominences. Installation involves removing the DSII module, unscrewing the black tube with a red filter from the end of the DSII module, replacing it with the new black tube from the anti-reflection filter, and reinstalling the DSII module.

Anti-Reflection Filter for LS80THa and LS100THa
The LS80THa and LS100THa H-alpha solar telescopes can be double-stacked by using the internal DSII
double-stack modules. This is a reasonably priced possibility for double-stacking. The DSII modules will reduce
the bandwidth to <0.5 Angstroms. The DSII module is designed to provide enhanced surface detail, allowing for
higher contrast views of the filaments and active regions.
But the DSII modules will also produce reflections that will be visible as strong glow around the sun. This glow is
no problem by observing the solar surface. But it could be a problem by observing prominences, and some
observers find this glow distracting.
The anti-reflection filters HRG80DS for LS80THa and HRG100DS for LS100THa are designed to solve this
problem. The filters will effectively reduce the reflections.
Installing the HRG80DS anti-reflection filter at LS80THa/DSII
The anti-reflection filter will be placed between Etalon of the telescope and DSII double-stack module, like it is
shown at the images below.
Remove the DSII double-stack module from your telescope. Now take the HRG anti-reflection filter and press the
two silver knobs together that the HRG housing fits into the telescope. Move the HRG inside the telescope as far
as it will go. Now you can again install your DSII module at the telescope, that’s all. Now you can start solar
observing.
Please note that the image will become some darker by using the anti-reflection filter.

Installing the HRG100DS anti-reflection filter at LS100THa/DSII
The anti-reflection filter will be placed between Etalon of the telescope and DSII double-stack module, like it is
shown at the images below.
Remove the DSII double-stack module from your telescope.
Now unscrew the black tube with red colored filter from the end of the DSII module. This black tube with red
colored filter will not longer be needed.
It will be replaced by the new black tube from the anti-reflection filter HRG100DS. Screw this new black tube with
anti-reflection filter on the DSII module. Now you can again install your DSII module at the telescope, that’s all.
Now you can start solar observing.
