Explanation:
Recorded near Wildon, Austria, the picture is a composite of two exposures; a relatively short exposure to feature the lunar surface and a longer exposure to capture background stars in the constellation Leo. Completely immersed in Earth's cone-shaped shadow during the total eclipse phase, the lunar surface is still illuminated by sunlight, reddened and refracted into the dark shadow region by a dusty atmosphere. As a result, familiar details of the Moon's nearside are easy to pick out, including the smooth lunar mare and the large ray crater Tycho. In this telescopic view, the background stars are faint and most would be invisible to the naked eye.
Explanation:
A red Moon rose over Cape Cod, Massachusetts, USA on March 3rd, immersed in Earth's shadow near the total phase of a lunar eclipse. This serene portrait of the eclipsed Moon in a dark blue twilight sky also features the Highland Lighthouse (aka Cape Cod lighthouse), another more locally familiar beacon in the night. Now automated, the 66 foot tall structure in use today was built in 1857. How often has there been an eclipse within view of the Highland light? For locations on planet Earth there are about two eclipse seasons each year. So, eclipses have actually had many chances to be part of the pictorial history of the Highland Lighthouse, including a total solar eclipse in 1932.
composite exposure 5 and 30 sec to show the background stars at 02h24 UT
Pete Lawrence had the nice idea to collect images taken over a big distance at the same time to show the parallax effect. Beside others he has chosen my and Paul Hyndman's image and did nice animations from them.
