Lunar Occultation of Antares August 24 2023

Lunar Occultation of Antares August 24 2023

This is image is about an hour after the re-appearance of Antares on the bright limb of the Moon.

Roll back a couple of hours and the Moon was barely visible behind a white smokey haze and Antares was not visible. The disappearance was definitely a long shot and was missed both imaging wise and visually through my 70mm refractor.

I waited a little over an hour later and the Moon was more distinct in the sky though I had given up being able to see the re-appearance. At the time of the re-appearance at 7:33pm I was watching intently hoping to see Antares cross the limb. By then Alex had joined me and was monitoring with binoculars. About 20 seconds after the predicted time I saw Antares momentarily. Alex confirmed this looking in my refractor. It was popping in and out of view through the smoke. The contrast of the Moon had definitely improved, but the ability to see Antares was still hampered by the smoke. Antares appeared very much like a pinpoint and the lens I was using just didn't resolve Antares through the smoke. Antares had emerged from across the crater called Langrenus.

When I got home an hour later I mounted a lens with an effective focal length of 420mm, By then the sky had darkened and the Moon had risen above the smoke.
