Baader CMOS-optimized L-RGB Filters

• 2" Filter removed from filter cell, specially selected for use with 2" Filter sliders of the Baader FCCT (Filter Changer Camera Tilter) for RASA 8 and QHY cameras

• RGB-R (595 – 690 mm)
• RGB-G (490 – 580 mm)
• RGB-B (400 – 510 mm

• UV/IR Cut (420 – 685 nm)
• Reflects harmful thermal radiation in the infrared spectral range
• Provides 98% transmission over the entire visible spectrum from 420 - 685 nm
• Prevents blurred star imaging with red-sensitive digital and CCD/CMOS cameras

• Optimized for modern CMOS cameras, but likewise excellent for older CCD camera technologies
• Anti-reflection RGB filter (red/green/blue) with extremely high transmission of the respective color channel, thus simultaneously reducing stray light and reflections to an unprecedented level
• Balanced RGB design allows subframes to be taken with the same exposure time – extremely important for automated imaging tasks
• Increased contrast
• Reflex-Blocker™ coatings
• FWHM on each filter category carefully designed to allow for 1:1:1 exposures, matched for typical CMOS quantum efficiency and s/n ratio
• Blackened edges all around, with filter-lead-side-indicator in the form of a black frontside outer rim, to additionally eliminate any reflection due to light falling onto the edge of a filter with filter-lead-side-indicator in the form of a telescope-sided black outer rim
• Each filter coated individually, with sealed coating edge (NOT cut out of a larger plate with coatings left exposed read more)
• Reflex-Blocker™ hard coated and planeoptically polished – with sealed coating edges (Life-Coat™)
• Life-Coat™: evermore hard coatings to enable a non-aging coating for life – even in a most adverse environment
