Optolong L-eNhance filter 1.25″

Optolong L-eNhance filter 1.25″: nebula photography with your color camera

The L-eNhance brought narrowband photography within reach of color cameras and is still one of the most popular nebula filters. Through two passbands, the filter lets through three emission lines: H-beta and OIII in a combined band of 24 nm, and H-alpha in a band of 10 nm. All other light, including street lighting, is blocked.

The result: emission nebulae emerge with surprising contrast from a single exposure series, even under a significantly light-polluted sky. In the 1.25-inch version, the filter fits into nosepieces and filter wheels with a 1.25-inch connection.

Who is L-eNhance for?

This is the entry-level filter in the L-series for nebula photography with a color camera or astro-modified DSLR. If you want narrower later on, the L-eXtreme (7 nm) and L-Ultimate (3 nm) are the next steps.

Technology

The optical glass is multi-coated with ion-assisted deposition: scratch-resistant, temperature-stable, and with high transmission at the emission lines.
