Shark Attack - LDN 1235/1251

On holiday in the Eifel in Germany and hoping for clear nights, but unfortunately it seems that most of the times it's clouded and lightning in the evening. So I already gave my hopes up a bit when yesterday evening I noticed it was clearing up. Against my feeling I decided to just build up the equipment and see what would happen. Somehow I was lucky and while there was lightning in the distance the sky kept clear right over my head until about 4 in the morning. So I decided to work on some dark nebulae as they are impossible to image from my home location.

I used my setup using the Spacecat and Nikon D810a with an Asiair controlling everything. This works really great, except for a few times the guiding just stopped without a reason, and so I was able to catch in total 29x300s of images of LDN 1235/1251. LDN 1235 is also known as the shark nebula but somehow this image makes me think of a shark lurking under water to catch the swimmer (LDN1251) at the surface.

During the imaging I took time to enjoy the Milky Way shining over me and see some nice details even with the naked eye. During the night quite a lot of Perseids were visible, sometimes very quick and shortly visible, but also a few that left a nice trail.

Thanks for watching and I hope for a few more nice nights to get even more detail out of this image in the coming nights.

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.
