Description:
Three bright galaxies in the same field of view at 40x. Brightest, M
66 is the most southest one, quite extended and having large core with
pretty bright halo fading gradually into darkness. M 65 is just to the
west (left in the telescope mirrored image), looking like "narrowed"
neighbour, with the core of same size, but fainter, as it is much more
elongated. Third galaxy in this group, NGC 3628 is, in my opinion, the
nicest one. With low surface brightness, it is larger than two M65 and
66 and it is mostly uniform, without central brightening. Its edges
are fading out slowly. I have not seen any other details in any of
these objects, even when switching to 100x. Sketch is available on the
URL mentioned below.
