Good report David. When you start comparing magnitudes and what you can observe visually, then magnitudes don't tell the whole story. 4945's mag is 9 and 5128 is 7 and can be spotted faintly in the finder, however I find that mag 12 galaxy 4462 in Corvus is a relatively easy pickup from home. I suppose that the smaller galaxies are easier to spot than the big diffuse or face on ones. Surface brightness is just as important as magnitude. Like you, I find that the bottom half of the 5128 "hamburger" is much fainter than the top requiring averted vision to see at all. The filter seems to be working great for you. Have you tried it on galaxies, or just nebulae?
