Ultra High Efficiency Nebula Filter - IDAS NBN-PV Filter
IDAS
has now developed a narrow-band nebula filter "NBN-PV
Filer". This filter utilizes IDAS MBT
(Multi Band-pass Technology),
offering
a very high cost performance.
IDAS NBN Filter Advantage:
While
the conventional high-contrast type nebula filter only cares about
O-III and H-beta, IDAS NBN-PV Filter maximizes
H-alpha and NII transmittance.
The
NBN-PV is suitable and effective for observation on planetary and diffuse emission
nebulae through
a CCD camera, conventional photo camera or even naked eyes.
