This is the view through my Astra IIIB sextant at sunset. It's a pretty wide lunar, about 122 degrees, near the limit of the sextant. A faint sunspot is visible near the center of the Sun's disk---it is more apparent in the images with unobstructed Sun.
There's a ridge of low mountains to my west, so the actual elevation of the Sun was about 5 degrees at the time of the photo, thus the Sun's image is still reasonably good. There's a bit of vignetting from top to bottom (the bottom is darker) because of the half-silvered horizon mirror. It might have been better to use the whole-horizon mirror for this shot, but there wasn't time to change it.
The camera is a Canon SX160, 1/200 second, f/5.9.
Cheers,
Peter
