The Optolong L2 Dual-Combo Set pairs two complementary filters for one-shot colour imaging: L-eXtreme , dual-narrowband filter (OIII-7nm & Ha-7nm), and the newly launched L-Synergy , a dual-narrowband filter (OIII-7nm & SII-7nm)
Tailored specifically for color camera astrophotographers, this set includes two premium filters: OIII & Hα (L-eXtreme),OIII & SII (L-Synergy).
This innovative combination breaks through the traditional limitations of narrowband imaging with color cameras. Without the need to switch to a monochrome camera or invest in an expensive SHO three-filter set, users can achieve stunning Hubble Palette images at a fraction of the cost and complexity.
The core appeal of this combination design lies in lowering barriers and expanding possibilities for colour camera users: it preserves the equipment advantages of colour cameras while enabling users to unlock “Hubble-like” creative capabilities at minimal cost through minimalist filter combination. Simultaneously, it offers greater flexibility for astrophotography.
