Sun and Moon (Fausto Lubatti)

Contains: Solar system body or event

Sun and Moon

This picture shows Sun and Moon taken with the same optics at few hours of distance: the picture of the Sun was taken in the morning of the solstice day, while the picture of the almost full Moon was taken the day after in the evening, 42 hours later, when it was 99.5% illuminated and few hours before perigee.

It can be seen how the apparent Moon diameter is larger, compared to the Sun diameter: a noticeable difference when the two images are side by side, probably more difficult to see in the sky without a reference.

Data of pictures

Both picture taken with a Canon EOS 5D Mark II body directly mounted at the focus of a vintage Celestron C90 (Maksutov-Cassegrain, 90 mm aperture, 1000 mm focal length, f11) at Melegnano, Italy.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
