F28X50OIII - CCD
Description
The F28X502OIII mode is useful for narrow-band imaging of O III 5007 Å. The field of view is 28" × 50".
Recommended Uses
This filter is recommended for deep high-resolution O III imaging.
Special Considerations
This filter has a significant red leak longward of 1 micron. Depending on the source spectrum, the contribution from red leak may swamp the contribution from line emission.
