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.

- Questions & Answers
Product QuestionsOnce 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?Question by: Stephen C Phillips on Jan 16, 2017 8:50:00 AMYes, this filter can be used, as long as you have the included 2" nosepiece attached and the 2" filter threaded onto the end. This filter cannot be used with a conventional T adapter without special adapters. If your scope needs a 2" reducer or flattener, you can also thread this filter onto the end of the optical corrector and then use ~37.5mm of T-thread spacers to get to the ideal 55mm from corrector to camera sensor on the back side.Answer by: Chris Hendren (Admin) on Jan 16, 2017 9:27:00 AM
