These will work with any aperture, but really make a difference for small to medium scopes for making making nebulosity stand out. When a regular wide band nebula filter which helps with brighter nebula like M17 and M 57 won't provide essential contrast as with M16 and the Veil Nebula, the narrowband Ultra High Contrast can help. The next step beyond this is the Oxygen 3.

These two filters will eliminate much of the wider spectrum so that the prominent wavelength of the illuminated gases will not be hidden by surrounding stars.
