175X Very close to Lambda Muscae and similar in size to NGC 4833 but with no sign of central concentration. Roughly circular splash of resolvable stars against stippled halo. The are some dark patches in the GC, one is v-shaped pointing to the west.

Very nice report Paddy. I recently spent some time on most of these targets recently at Coonabarabran.
When observing this globular its always worth checking out
"The Dark Doodad" which is just South of NGC 4372. It is a really nice dark Nebula, almost 3 degrees long and about 10' wide.

250X A truly stunning and intricate PN. A bright star at the western end of the PN which has an E-W bar which curves south at the eastern end and bifurcates at the western end. The bar sits within a broad halo of fainter nebulosity with a distinct outer edge and dark lobes either side of the central bar. The northern lobe has a more marked outer border. There is further nebulosity beyond the halo to the southeast. The shape is reminiscent of a section through a seashell with a thick spiral core and a delicate outer shell. . Brightens with UHC filter. With OIII filter the spaces between the spiral and the shell glow a little more as does the patch to the east. 440X Remains very bright and distinct and confirms structure described above but a few bright patches appear the most obvious in the southern lobe.

When we were at Coonabarabran recently with our American and Korean visitors on our OZSKY 2011 trip, we spent a lot of time on this target with the 30" SDM and the 25" Obsession.
It really is a wonderful planetary. One of the Koreans and one of the Americans commented that they felt it was the nicest planetary they had ever seen.
Cheers,
