Rho Ophiuchi Cloud Complex and M4 over the Atlantic Ocean

I have been looking for shooting the cloud of Rho Ophiuchi for a long time : all those nice colors in the multiple emission and reflection nebulas...

Unfortunately, it is very low on horizon and my access to the Southern skies is limited to summer, where the nebula rise very early (17h00) and set very early too (0h30), without reaching more than 15-20 degrees over the horizon line.

I wasn't expecting much with such conditions : and indeed, with the only 3h30 I could catch in 2 nights (not enough clear nights to do more), I got lots of noise and awful gradients though the streetlights are off during the night in that city far from other big cities.

Anyway, I seize this opportunity to hide these imperfections through a nice composition with the lights from the lighthouse "les Poulains" just over the Ocean, and mix a day picture behind it to put that in context.

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.
