The IDAS LPS-V4 filter is designed to
provide maximum contrast between key
astronomical emission lines and a light
polluted sky. These filters incorporate IDAS
MBT, UFP, and IGAD
technologies to insure undegraded and extremely
durable optical performance.
Features include:
- Near IR is blocked completely, eliminating the need for an additional filter to block IR.
- Narrower H-alpha bandpass. In combination with a Kenko R1 filter, this can be used as a 19nm bandpass H-alpha filter.

- Easy creation of H-alpha enhanced color images
LPS-V4 filters are available as camera-body-mounted
filters (LPS-V4-37) for

screw-in filters for telescopes or telephoto lenses in the following sizes:
