I didn't mean to imply all those H-ß objects were easy or even visible to a 12.5" aperture.
I mentioned the 12.5" aperture because the original post wanted a list of objects at the edge of visibility for that aperture, and there are just too many thousands of objects to make such a list. Most are not H-ß objects, of course.
He was also mentioning an H-ß filter, so I gave him a list of faint targets at the edge of visibility using that filter. B33, the Horsehead, is one such.
My list is northern hemisphere-biased, and a southern list would contain many objects not visible up north. You guys would know best what objects to add to the list of H-ß objects in deep southern skies.
Observer experience counts, of course, but I think light pollution is the biggest factor keeping observers from going faint. If you have truly dark skies, it's amazing what can actually be seen with modest apertures.
