Shooting emission nebulae with a color camera or DSLR from a neighborhood with streetlights is difficult because the scattered light washes out your shots. The Optolong L-Synergy is a narrowband filter from the L-series, designed for color cameras and DSLRs. It lets through mostly the light from glowing gas in the nebulae and blocks out much of the light outside of them.<\/p>\n\n\n\n

The 2 inch version screws on a filter tray or filter holder<\/a>, or on a field marker with filter wire<\/a> or a reducer with a 2 inch filter thread.<\/p>\n\n\n\n

Before ordering, check which size you need. For galaxies and reflection nebulae, a narrowband filter is not the right choice, as it emits light across the entire spectrum. Never photograph with it towards the sun.<\/p>\n\n\n\n

There is also a similar series the L2 Dual-Combo set with two filters<\/a>.<\/p>","protected":false},"excerpt":{"rendered":"
