  • Antlia LRGB-V Pro Filter Set

    The Antlia LRGB-V Pro Filter Set is the foundation for creating detailed, true-color astronomical images with modern monochrome cameras, offered in 5 distinct sizes to integrate into any optical train. This four-filter system isolates the primary red, green, and blue wavelengths, plus a high-transmission luminance channel, allowing you to capture deep-sky objects with accurate color rendition and maximum detail. By capturing each channel separately, you gain complete control over color balance and contrast during processing.

    LRGB-V Pro: A 4-Filter System for Monochrome Imaging

    Shooting with a monochrome sensor and an LRGB filter set is the definitive method for high-fidelity astrophotography. The Antlia LRGB-V Pro set enables this by separating the incoming light into four distinct channels. The high-transmission Luminance (L) filter captures fine detail and signal depth, while the Red (R), Green (G), and Blue (B) filters gather the color information, which is later combined to create a final, full-color image far richer than what a one-shot color camera can produce.

    Antlia V-Pro Series Optical Engineering

    The "V-Pro" designation signifies Antlia's commitment to optical precision for serious imagers. Each filter in the set is designed to minimize internal reflections and halos around bright stars through advanced anti-reflection coatings. This ensures that the signal from your target is preserved with high contrast against a dark sky background. The filters are engineered to be parfocal, meaning you shouldn't need to refocus when switching between the L, R, G, and B filters, saving valuable imaging time and preventing image shift.

    5 Filter Formats for Any Modern Imaging Train

    To prevent vignetting and accommodate different sensor sizes, the Antlia LRGB-V Pro Filter Set is available in 5 standard formats. This selection ensures a match for nearly any filter wheel or filter drawer on the market, from small planetary setups to large-format deep-sky systems.

    • Mounted (1.25" & 2"): Thread directly into standard filter wheels and drawers, offering protection and easy handling for cameras with smaller to medium-sized sensors.
    • Unmounted (31mm, 36mm, & 50mm): Designed for modern filter wheels that use retaining rings or carousels. The larger 36mm and 50mm sizes are essential for preventing vignetting on full-frame and larger sensors, especially in fast optical systems.

  • What is the advantage of using the Antlia LRGB-V Pro set over a color camera?

    Using the Antlia LRGB-V Pro filters with a monochrome camera allows you to capture significantly more signal, especially through the clear Luminance filter. This results in sharper, more detailed final images. You also gain complete control over the color balance in post-processing, which is not possible with a one-shot-color camera's fixed Bayer matrix.

    Are the Antlia LRGB-V Pro filters parfocal?

    Yes, filters in the V-Pro series are designed to be parfocal. This means that after achieving focus with one filter (typically the Luminance), you should be able to switch to the R, G, or B filters without a significant change in focus. This is a critical feature that streamlines automated imaging sequences.

    How do I choose between mounted and unmounted Antlia LRGB-V Pro filters?

    Your choice depends on your filter wheel or drawer. Mounted filters (1.25" and 2") screw directly into threaded ports and are easier to handle. Unmounted filters (31mm, 36mm, 50mm) are required for many modern filter wheels that clamp the filter in place, and they often provide a larger clear aperture for a given size, which helps reduce vignetting.

    What is a good starting exposure ratio for the Antlia LRGB-V Pro set on a galaxy like the Triangulum Galaxy (M33)?

    A common starting point for LRGB imaging on a galaxy is a 1:1:1 ratio for the RGB channels, with the Luminance channel receiving at least three times the total exposure of a single color channel. For M33, you might start with L: 15 minutes, R: 5 minutes, G: 5 minutes, B: 5 minutes, and then adjust based on your sky conditions and camera's sensitivity.

    Will the 36mm unmounted Antlia filters work with my 8" f/4 Newtonian and an APS-C sensor?

    Yes, the 36mm unmounted filter size is an excellent match for that combination. An f/4 Newtonian produces a steep light cone, and the 36mm format provides a sufficient clear aperture to fully illuminate an APS-C sensor without significant vignetting, which could be a problem with smaller 1.25" filters in such a fast system.

    Do I need a UV/IR cut filter with the Antlia LRGB-V Pro set?

    No, you do not. The Luminance filter in the Antlia LRGB-V Pro set has built-in UV and IR blocking, and the individual R, G, and B filters only pass their specific visible light bandpasses. This ensures that only the desired wavelengths of light reach the sensor, resulting in sharper stars and better color fidelity.
