Description:
120X-NGC4904 appears as a quite faint diffuse oval. A little brighter in the
center. It is visable with direct vision with some difficulty.
Narrow Band Filter does not help any.
220X-NGC4904 shows a faint, diffuse, slightly oval halo with a very little
brighter bar. I cannot detect a central bulge. the sky is too bright for
averted vision to help. The galaxy is easier to find when jiggling the scope.
The seeing and rapid temperature drop will not support more power.
