I'll likely try to redo a couple of these, but I pre-observed many of them to see if they were suitable targets. I was pretty happy with this capture taken with the Super C8 + Starizona and the ASI533MM-Pro with UV/IR.

My notes from the session:
Very cool, but tiny, (right) triangular shaped galaxy group. These are all elliptical or S0 type and so are fairly bright and generally uniform. One of the galaxies (NGC6027B) has a faint extension below it that was originally thought to be the 6th member of the group (NGC6027E), but that is now know to be an extension of the brighter galaxy (type Scd). I think this shows pretty clearly in my capture. NGC6027C is also classed as an Sdm type and so it shows a bit of a brighter core with an elongated extended halo. The extension off N6027B is strange as it does not appear to be connected to the main galaxy at the 18 minute mark. It's just a fairly uniform bright patch with a darker inner section right where it meets the main galaxy. Tiny, round and faint NGC6027D is right near N6027B and at right angles to it's faint extension. At about 30m, NGC6027A (the brightest member of the group), begins to show a faint halo around its mostly uniform bright oval core (2:1). I've seen sharper captures (Hubble) where there is a fine, dark lane crossing this halo, but I see no hint in my capture. NGC6027D starts to show a little internal structure at 36m and at 175% zoom. In the same capture that shows the dark lane in N6027B I see that N6027D is a clumpy, face-on spiral and this variation in brightness that I'm seeing is the brighter sections in those arms. At the 40m mark, it's clear that N6027E does connect and actually wrap around N6027B. In fact, it's apparent that there is material between all the member galaxies toward the center of this group.
