About this image

Good conditions and excellent seeing (Ant II) for this morning's session in a clear slot before clouds rolled in and the seeing degraded. Mercury is just past half-phase, and a little less than 7 arc seconds in diameter. The final stack used about 4% of the total captured frames, which is a large proportion for Mercury, and the quality was such that no manual frame selection was required. The final image compares very well with the blurred WinJupos map, although as usual the wavelet processing has made the planet look more of a crescent than it really is.

Great image Chris. Perseverance pays off with the seeing! No more clear mornings here.
