Most deep sky observers are quite familiar with Stephan's quintet, a faint grouping of five galaxies in Pegasus. They are a visually challenging target in winter skies and are frequently imaged by amateurs as well.
An equally challenging grouping of five galaxies appears to be overlooked by both visual observers and imagers. Specifically, the NGC6962 grouping in Aquarius:
1. NGC 6962: The largest and brightest at mag 12.1.
2. NGC 6961: The fifth brightest member of the group at mag 13.7.
3. NGC 6967: The third brightest member of the group at mag 13.1.
4. NGC 6959: The fourth brightest member of the group at mag 13.7.
5. NGC 6964: The second brightest member of the group at mag 13.0. It touches the SE edge of NGC NGC 6962.
Details on the group are sparse. Information can be had in the Observer's Guide and here:

To up the ante, Aquarius doesn't ride as high for most observers as Pegasus, so excellent seeing and transparency are likely requirements to see the members clearly. Obviously, this target is a challenge object, probably more so the Stephan's Quintet. It would also be interesting to see if imagers can push the envelope and capture this grouping.
