NGC 6334 Cat´ s Paw nebula and NGC 6357 the Lobster nebula

This is another Object I had on my todo list during my croatian holiday. I cannot see this nebula from my home in Austria. During the exposure I had already the sea level on more than half an hour in the field of view (5 degrees above the horizon).

I was not sure if this picture will work at all. The scope was more or less horizontal and over the sea is always some haze. Its not a great picture, but I am happy I could make it.

Whats was interesting, that refraction of light is shifting positions of the stars significantly already close to the horizon. I had to cut the lowest part of the picture because of that! What was at the beginnig of the exposure 8-10 deg above sea level, was later only 4-5 deg!

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.
