This arrived Friday, and I was able to try it in my AA Herschel wedge, using a variety of ep and mags.

While it does transmit at 540nm (green) wavelength, I found it produced no increase in feature contrast.

thx for the infos .

Hi, I've got the Baader version of this, actually two of them; the 10nm and the new 7.5nm. I would have to agree, I've used them both visually on an f/11.4 80mm with the Baader 5.0 solar film and with the exception of the green, I don't really see a difference.
However, for stacking photos with a DSLR and the same scope, it does bring out more detail as opposed to not using one.

Filters are great, but my eyes are not young and as sensitive as a camera...
