[rcheshire (Rowland)]

The image of the LMC was taken last night from Snake Valley.

There are 2 or 3 concentric rings near the top left edge of the image that seem to be centered on a star - hand drawn line around the area.

Unfortunately, the jpeg doesn't illustrate it very clearly. Two cropped areas from different processing methods. Any idea what this might be. Google led to academic papers about microlensing in this area.

Thanks

Rowland.
