What could be better for a first image of 2024 than a Moroccan-Chilean collaboration between friends!

We're really pleased to present our latest image and our first collaboration between APO Team and Yann. It's a real pleasure to be able to shoot in these conditions with friends!

The Dolphin's Head nebula, Sh2-308.

APO Team's TOA-150 gave us great detail on the Dolphin thanks to its 1,100mm focal length, while the FSQ-106's 382mm focal length gave us a wide field and an impression of immensity around the Dolphin.

The data on the Dolphin are cumulated with the two set-ups to remove as much background noise as possible.

Just west of the Dolphin we can see the planetary nebula G234.9-09.7, shown here in great detail.

We're delighted to have been able to highlight the dust in this region. This was mainly made possible by the excellent sky quality at the two shooting sites, Oukaimeden Observatory in the High Atlas for Morocco and SpaceObs in the Atacama for Chile.

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.
