DSII Internal Double Stack module for LS100THa
Double stacking provides a truly enhanced high definition view of the Sun's surface details. It lowers the band pass of the system from <0.7 Angstroms to <0.5 Angstroms which really makes the surface “pop”! The Lunt LS100THa Hydrogen-Alpha Solar Telescope can be internally double stacked by purchasing the Lunt DSII/LS100T module in conjunction with a LS100THa (Lunt will stack it at the factory) but you can add the DSII/LS100T to your own LS100THa at any time.
The LS100THa does not need to be returned to the factory for double stacking as long as you have a newer model of the LS100THa. You can tell if yours is compatible by checking to see if you have a red anodized front cell. If so, you are good to go. If you have an older model of the LS100THa with just a white tube (and no red) you will need to upgrade the scope before it will be able to accept the internal double stack DSII/LS100T.
