Globular cluster M10 (NGC 6254), located in Ophiuchus.

At declintation -4, this fellow reaches it's highest point in my northern sky in the summer, when it is conveniently placed overhead at around midnight. It's maximum altitude is only 32 degrees and it peeks through some inconveniently placed trees, so I think this represents about the southernmost object I can reasonably try to image from my deck.

Exposure: RGB 20-20-40, 5 minute sub-exposures, Luminance artificially created by combining all colour images.
