Description

Double stacking provides a truly enhanced, high definition view of the Sun’s surface details. It lowers the bandpass of the system from < 0.7 Angstroms to < 0.5 Angstroms, which really makes the surface “pop”!

The Lunt LS100THa can be internally double-stacked at the time of purchase or anytime thereafter. The LS100THa does not need to be returned to the factory for double-stacking as long as you have the red anodized front cell on your telescope. If you have an older model (just a white tube with no red) you will need to upgrade the scope before using the internal double stack DSII-LS100THa. Should that be your situation, contact us for upgrade information.

Natalie ★★★★★

I’ve been using this module for a few weeks now, and the contrast on sunspots is noticeably sharper—it’s like seeing the surface with new clarity. The tunability is a nice bonus, letting me dial in just the right level of detail. It’s a solid upgrade that’s made solar viewing much more rewarding.

Ruby ★★★★★

The double stack really cleans up the granulation texture across the solar surface, much more defined than with a single filter. It snaps in easily and stays snug during the session.

Zoe ★★★★★

The contrast on solar surface details jumped dramatically after adding this internal module—I can finally resolve those tiny filament structures I'd only seen in photos. Setup was straightforward, though you definitely want to follow the caution about careful selection since these are final sale.
