We saw an Internet post (see Reviews tab) about our filter performance, and thought it would be instructive to actually see images of an artificial star taken through an f/5 test telescope at high power with the filters positioned in front of the diagonal, part of our 100% Q.C. check. Can you guess which random sample is a Tele Vue Bandmate™ NebuStar, and which is another brand? (Both shown in best focus positions at the same scale).
