The occultation of Saturn by the Moon - 2019-08-12

Acquisition type: Lucky imaging

I had clear skies for the occultation of Saturn by the Moon, although as you can see from the video (via my DropBox), the seeing wasn't great.

To get the exposure such that Saturn could be seen meant over exposing the Moon as you can see in the video. To produce this image I used an HDR combination of the Moon and the planet. After the occultation I wound the gain down so the moon was properly exposed and then made a 4 minute video at 4fps before processing using the lucky imaging technique. With some difficulty I processed Saturn, by cropping away the moon and stacking the resultant video. I only had a few hundred images and the seeing wasn't great so the resultant Saturn image is not the highest resolution Saturn image I have ever produced. I then took a still from the movie and using this as a template inserted the planet image at a point where it was partially occulted by the Moon.

This is the link to actual video in an MP4 format which is not supported on AstroBin and is probably too large anyway.

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.
