L-RGB Colorfilter

• Batch-tested for consistency.
• High quality dichroic/dielectric coatings. 
• Anti-Reflection coating to reduce star-halos - stackable.
• UV/IR block for imaging - star bloat reduction with refractors.
• Ultra-flat glass by Schott Germany.
• Precision CNC machined filter cell for strain-free mounting and freedom from tilt.

The new Astronomik Deep-Sky RGB filter set is specially designed for the needs of demanding astrophotographers to achieve maximum image quality with all CCD cameras. Use the Deep-Sky RGB filter set to achieve images with unparalleled sharpness, contrast range and vivid colours.

• Filter set for colour images with monochrome cameras
• Transmission >95%
• Diameter 36mm

With this filter set, you can take visual RGB images, VIS-IR RGB images and, if using an optional IR pass filter, NIR RGB images.

• color rendering similar to that of the human
• versatile due to transmissions in VIS and NIR
• suitable for cameras with 1.25" connection
• reflex-reducing design
• more durable coating for safer cleaning

The luminance channel is very important for a successful astrophoto! Sharpness, contrast and low noise of the luminance data are decisive for achieving the best possible quality in the final result!

The task of the L filter is to maximise transmission over the entire visible spectrum, because the combination of the widest possible aperture and high transmission makes it possible to capture the greatest possible number of photons.

• Filter 36mm with ring mount
• Photographically usable
• UV and IR are blocked
