Hutech/IDAS Reflection Suppressed (RS) Color Filter Set

Hutech/IDAS Reflection Suppressed (RS) Colour Filter Set.

New Set Of LRGB Colour Filters For CCD Imagers.
 

Hutech/IDAS RS (Reflection Suppression) technology filters are specifically designed to address the problem of internal reflections common in filtered CCD images when bright stars are present in the field of view (This problem is especially common in wide-field images). The IDAS RS filter set reduces surface reflections to less than 4% of conventional dichroic filters such as the IDAS Type II LRGB set.In addition to the suppression of reflections, the IDAS RS filters feature gentle, overlapping bandpasses which match the response of the human eye more closely, making color balancing for realistic color simpler. The complete set includes 4 filters - luminance(L) and RGB components.To optimize the performance of IDAS RS LRGB filters, adding a UV-blocking filter is recommended if your camera does not include a UV-blocking coating.

SBIG STL users: adding a UV-blocking filter is recommended in the optical train, or
optionally, replace the UV-blocking filter in the camera's D-block with an IDAS UV blocker
provided by Hutech. FLI users: an additional UV-block filter is not required if the camera's clear window has a UV -blocking coating. If not, an additional UV-blocking filter is highly recommended.
