  • Presented in a 2" (48mm) threaded format.
  • CCD imaging can also benefit from the IDAS Light Pollution Suppression (LPS) Filter as it provides an added (signal-to-noise) edge.
  • IDAS has now tweaked the LPS-P2 to more optimize for one-shot color and modified DSLR cameras with the LPS-D1.

Now IDAS has tweaked the LPS-P2 to more optimize for one-shot color and modified DSLRs cameras. Please see the response curve in the images above.

The key concept on the LPS-D1 is to reduce the reddish background cast like HEUIB-II while blocking light pollution as much as it can. Although LPS-P2 is effectively blocking light pollution while retaining good color balance comparing with other brand filters, it was not as good as HEUIB-II at shown at following my test when color camera was used.

The LPS-D1 is the answer.

As the response curve indicates, LPS-D1 loses SII emission line while LPS-P2 didn’t. So this is why it's basically intended to be used with one-shot color cameras.
