IDAS Light Pollution Suppression (LPS) Filter w/ SCT Adapter - 2"


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.

Once this is mounted to the rear cell will I then be able to mount other equipment, such as a focal reducer, as well?

Can this be threaded directly into the reducer or coma corrector and inserted into the focuser (I.E. No change in backfocus spacing distance) , or does it need to be threaded directly in front of the sensor such as into an OAG?
