Thanks Ajames, will try these next time, should Melbourne's moronic weather cooperate.
Gum 15 sounds like a good challenge.
Here's a few more to add to that list, based on my own observations from my 4.5-5 NELM sky with my 10" dob:
Gum 39
50' WNW of Lamba Centauri. Virtually invisible without a filter, but at low powers with a UHC a faint elongated haze is visible oriented E-W. A 9th mag star lies at its southern edge. An arc of 3 10-11th mag stars forms the nebula's eastern border.
IC 2872
Located adjecent to Gum 39's southern edge. Have not successfully spotted it.
Cederblad 122
Extensive nebulosity located just E of the coalsack, at approx RA 13h 28m, Dec -64º. I have seen the section between the open clusters Cr 271 and Ru 16, centered at approx RA13h 27m, Dec -63º40' in my 10" at low power with a filter. It appeared as a faint, stubby, elongated smudge stretching between the two aforementioned clusters, with its western boundary clearly defined by an embedded dark nebula. I have also seen this nebulosity with an NP101 and a 31mm Naglar without filtration at a dark sky site.
