Acquisition type: Lucky imaging

The star of Bethelem, for my daughter Helena!

Acquired on a very cloudy evening. Such a luck a whole in the clouds just appeared at the right time, in the right location, giving me about just some minutes to align, focus and capture.

Both planets in the same picture: ~ 47 sec

Saturn: additional 149 sec

Jupiter: additional 111 sec

Captured both planets, separated the Ser-files with PIPP and processed those together with the single captures of Saturn and Jupiter with Autostakkert, respectively.

After processing (Autostakkert for Stacking, Registax for sharpening), I copied the Saturn and Jupiter back on top of the conjunction image, which I pretty much stretched to dark, after I matched the planets positions.

On Dec, 20th both planets were just close enough, so that I could have them both on the sensor in the barlowed (f=2800mm with Baader Hyperion Zoom 2.25x Barlow lens plus spacer) image train. So so lucky! The only other day, when they were visible was on Dec, 18th. But due to the distance between them only at 1000mm focal length.

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.
