Atik LRGB Filter da 31.8mm

Codice articolo: ATIKLRGB1

The LRGB filter set consists of Luminance, Red, Green and Blue filters that have been designed for CCD cameras to image deep sky objects, galaxies and stars in their natural colour

• ♦ Set for tricolor imaging with monochrome cameras
• ♦ Small overlap of blue and green filters, as with your eye, thus natural color of the O-III emission
• ♦ Gap between green and red filters blocks light pollution of sodium lamps
• ♦ >95% average transmission in each band
• ♦ The filter images show the colors as seen from that angle, the mechanical implementation varies with each set.

If a natural colour representation is what you want from you deep-sky imaging, an LRGB filter set should be your first choice. With [O III] emission overlapping on the blue and green filters to allow high efficiency and natural colour imaging of all deep-sky objects. The gap between green and red filters serves to block out the light pollution line at 589 nm and improves the colour of your images.
