Baader CMOS-optimized L-RGB Filters

New CMOS-optimized L-RGB filters from Baader Planetarium with Reflex-Blocker™ and Life-Coat™. Now with 47.4 mm unmounted for use with FCCT

• 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
• Baader CMOS RGB Bandpass Filter
  • RGB-R (595 – 690 mm)
  • RGB-G (490 – 580 mm)
  • RGB-B (400 – 510 mm
  • Baader CMOS UV IR Bandpass L-Filter
    • 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
    • The new generation of Baader CMOS-optimized filters features:
      • 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
