Baader Planetarium RGB 50mm Square Filter Set with UV/IR Cut L-Filter and Clear Filter

Discover the transformative power of the Alpine Astronomical Baader L-RGB-C CCD Imaging Filter Set, a versatile tool for photographers and videographers aiming to create breathtaking composite images of celestial bodies like nebulae and planets. This high-quality filter set is designed for monochromatic imaging, allowing you to capture your subject in each of the three primary colors - red, green, and blue. By layering these images in post-production using specialized software, you can create a spectrum of colors or emphasize the natural properties of your subject.

This innovative filter set includes more than just the three primary imaging filters. It also features a clear focusing filter and a luminance filter. The clear filter is your first step to achieving sharp, focused images. It simplifies the process of accurately judging focus sharpness, ensuring that your images captured with the colored filters are as sharp as possible. This is because the clear filter is parfocal with the colored ones, meaning once the focus is set with the clear filter, the focus remains consistent with the colored filters.

The luminance filter is a game-changer in the world of photography and videography. It effectively blocks ultraviolet (UV) and infrared (IR) light, allowing only the visual spectrum to pass through. This is particularly beneficial as many of today's imaging sensors are sensitive to IR and UV wavelengths. By stacking the luminance filter with any of the colored filters, you can eliminate ghosting caused by bands outside the visible spectrum interfering with your image, particularly with the blue and red filters.

Each filter in this set is planeoptically polished and anti-reflection multi-coated, ensuring high and uniform light transmission across the entire surface. This maximizes brightness and minimizes distortion, halos, and reflections. With a transmittance rate of over 95%, and all filters being parfocal, exposure times remain consistent when switching colors or even when not using the filters at all. This durable and colorful 50mm square filter set is offered as an unmounted 50x50mm square option, making it suitable for custom applications and imaging systems.
