Used IDAS 77mm LPS D1 Filter - SOLD
IDAS has upgraded their LPS-P2 filters to better accommodate one-shot color and modified DSLR cameras. You can view the response curve in the above images.
The new LPS-D1 filter's most important aim is the reduction of the reddish background cast like HEUIB-II while preventing as much light pollution as possible. Even though in comparison with other brand filters, the LPS-P2 did a sufficient job of blocking light pollution while maintaining good color balance, it did not live up to HEUIB-II when a color camera was employed.
The LPS-D1 is the solution.
As indicated by the response curve, while the LPS-P2 does not lose SII emission lines, the LPS-D1 does. For this reason, the LPS-D1 should be used with one-shot color cameras.
Note: Light pollution suppression filters are not a perfect substitute for dark skies.
