IDAS Light Pollution Suppression (LPS) Filter - 1.25"
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.

Product QuestionsQuestion by: John Pelafigue on Sep 2, 2015 12:15:00 PMUnfortunately, no. The Canon 300mm f/2.8L IS lens uses a 52mm gelatin (unmounted) filter in the drop-in holder. As all of the IDAS filters are mounted glass, the stock drop-in adapter does not accept any IDAS LPS filters. Hutech does make a Canon APS-C clip in filter, but for full frame you would have to buy a Canon 52mm threaded drop -in filter adapter (Canon part# 4773B001) and then we would need to special order you a 52mm IDAS LPS filter.
