DSII/LS100THA - LS100THA 專用內部雙層堆疊模組

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.

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.

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.
