Omegon Pro Veil SII Filter 3nm 2 inch

Omegon Pro Veil SII Filter 3nm 2 inch: 3 nm on the sulfur line

This filter limits the transmission to 3 nanometers around the emission line of ionized sulfur. It blocks virtually all interfering artificial light and lets through only the red to orange sulfur light.

Pro Veil is Omegon's narrow-band series for astrophotography. Each filter comes in a 2-inch aluminum mount with a sturdy protective case.

Make fine structures visible

The narrow pass makes the background dark and emphasizes delicate nebula structures. Even under urban light pollution, subtle details that normally disappear are preserved.

Strengthening the weakest channel

Sulfur-II emission is in most nebulae the weakest of the three SHO channels. Exactly there, a narrower band helps: the background signal drops faster than the object signal, improving the ratio.

Schedule lighting

Expect long exposure times for this channel. Fast optics and a well-tracking mount make the difference between a usable and a noisy result.

Featured accessories

Combine with the Pro Veil H-Alpha 3nm and Pro Veil OIII 3nm for a consistent 3 nm set in the same filter wheel.
