Lumicon LF3025 overview

  • 1Description

The original Lumicon 1.25" Ultra High Contrast Filter is unbeatable for revealing nebulosity. This is achieved by passing three nebula emission lines-the two doubly ionized oxygen lines (496 and 501nm) and the H-beta line (486nm)-while blocking light-pollution and Sky Glow. The result is superb views of the Orion, Lagoon, Swan and other extended nebulae.

The 1.25" filters employ industry-standard 1.125" x 42 tpi threads (except for Questar/Brandon, which use a thread pattern unique to Questar). The 48 mm filters employ industry-standard 48 x 0.75 mm threading, which thread into 2" eyepieces. All larger filters use the given size with 0.75 mm pitch (e.g. a 72 mm Minus Violet filter has 72 x 0.75 mm threads).

Note: Recommended for telescopes 8" and larger in aperture

The ultimate nebula filter
To ensure that your Lumicon filter remains the world's best, the strictest quality control standards are employed throughout the production process
Each Lumicon Ultra High Contrast Filter is individually inspected and proudly inscribed with the percentage of light transmittance of the OIII and H-beta emission lines

    Lumicon LF3025 reviews

    Ultra High Contrast 1.25" Filter is rated 5.0 out of 5 by 2.
    Rated 5 out of 5 by from Big help with light pollution Living in the suburb of a major city, this filter improves the view of DSOs. Mostly in that it makes the background darker so that there is more contrast in the DSOs. Viewing from a dark sky location is still better but at least using this filter makes it worth the trouble to chase after them from my backyard. Can't wait to try it on the Orion Nebula this winter.

    Rated 5 out of 5 by from Seems very nice, but it is my first one The construction is fine, the glass and coating too. But it is my first astronomical filter, so I can't say something more precise about its qualities. Images seem through it looks bluish and darker, as Lumicon say in their website. Bought to use everywhere: in city or darker sites; for visual and photographic observations.
