Ke ?

umm, CCDs generally dont have exposure times short enough to handle the moon, and I dont have a neutral density filter (who has ?), so the Ha filter served that purpose I guess. The point was, the NB filter worked on a broadband refective scource, and probably sharpened detail a bit on the way, which was a slightly interesting left field result on a CCD others might find interesting, ive never bothered before cause I thought it wouldnt work.

In what way could I have done this with a DS rig to make it less strange?, And, others have done a better job with fast webby type cams with no filters, so?.
