Idas LPS-V4-48

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.
• Retains the excellent color balance of the LPS-V3 filter when one-shot color cameras are used.
• Easy creation of H-alpha enhanced color images
