The 1.25Inch H-Alpha with its 12 nm bandwith is specially made for CCD photography. The light of the emission nebulas passes but nearly the whole remaining spectrum will be blocked.

At the H-alpha wavelength around 565.3 nm the filter has the maximum transmission around 99 %. So you can photograph nebulas like Northamerica Nebula or Rosette Nebula even in suburbs.

The bandwith of 12 nm is ideal for the common CCDs, and you can get good results with nearly every focal ratio up to f/10.
