Player One 1.25" LRGB Filter Set

Overview. The Player One 1.25" LRGB Filter Set is an S-series broadband filter set for producing true-color images with monochrome astronomy cameras. By capturing separate Luminance, Red, Green, and Blue channels and combining them, the set yields natural color across galaxies, star clusters, and broadband targets. Each filter is built on a high-quality optical glass substrate with a multi-layer composite coating and threads into standard 1.25" filter mounts.

Who It's For. The set suits imagers running monochrome cameras who want full-color results with the resolution and sensitivity advantages of mono capture, whether photographing galaxies, reflection nebulae, or star fields.

Key Features & Design.

• Complete LRGB channel coverage: Luminance, Red, Green, and Blue filters combine into balanced true-color images.
• High throughput: approximately 95% transmittance in-band keeps exposures efficient.
• Off-band blocking: OD3 blocking (less than 0.1% off-band transmission) with NIR cutoff across 700–1100nm holds channel separation clean.
• Parfocal, precision surfaces: 1/4 lambda surface accuracy on a 2.0 ±0.03 mm substrate supports sharp, consistent focus across channels.
• Standard 1.25" format: M28.5×0.6 cells thread into common filter wheels and drawers.

Optical/Mechanical Design. Each filter uses a multi-layer composite coating on a 2.0 ±0.03 mm high-quality optical glass substrate polished to 1/4 lambda on both surfaces. In-band transmittance is about 95%, with OD3 off-band blocking (<0.1% transmission) and near-infrared blocking from 700–1100nm to keep the Red, Green, and Blue channels well separated and the infrared leak controlled. The anodized cells use M28.5×0.6 (1.25") threads and measure 7.5mm overall (5mm body plus 2.5mm thread).

Recommended Uses. True-color imaging of galaxies, globular and open clusters, reflection nebulae, and broadband deep-sky targets; the Luminance filter also serves as a high-throughput detail channel layered over narrowband or RGB data.

Compatibility & Accessory Notes. The M28.5×0.6 cells fit standard 1.25" filter wheels, drawers, and nosepieces. The set is intended for monochrome cameras. It complements Player One narrowband filters in a mixed broadband-plus-narrowband workflow.

Good to Know Before You Order.

• Set contents: Player One does not publish the exact packaged quantity or per-channel bandpass figures for this set on the product page, so those are not stated here; contact us if you need confirmation.
• Shipping weight: a packaged weight is not published by the manufacturer.
• Camera type: the set is designed for monochrome imaging cameras.

FAQ.

Is it difficult to set up? No. Each filter threads into a standard 1.25" filter wheel or drawer, and the parfocal design keeps refocusing between channels minimal.

Why use LRGB instead of a color camera? Monochrome capture with LRGB filters records more light per pixel and higher resolution, then combines the channels for clean, controllable color.

Bottom Line. A well-coated, high-transmission LRGB set in the convenient 1.25" format, this Player One filter set gives monochrome imagers a straightforward path to balanced true-color results.
