LDN 1235. The Shark Nebula. Imaged through an unexpected ground fog bank that rolled in off the Atlantic Ocean!!

This is LDN 1235, The Shark Nebula. A dark nebula. Been a while since I have tried dark nebula, and last night seemed like a great opportunity. However, when you live next to a giant body of water, like I do, and the dew point and temp hit a certain limit, fog forms. We usually get it more in August here, than in October, but the seasons are changing. So all of a sudden I looked outside as I was getting some weird guiding numbers, and lo and behold, I could no longer see my scope on the driveway where I set it up! I went out to take a look. a big fog bank had come up from the marsh. However, when I looked up, I still had a pretty good sky. So I kept imaging till it finally got so thick, it was not longer worth trying. I was able to get 33 images at 300sec each. not perfect for a dark nebula, I was going for at least 70, but it worked. This is a fun nebula to try, and I did go back tonight, only to have a much thicker fog bank roll in after about 16 images...Like I said, life as an astrophotgrapher, near a big ocean! Clear skies??

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.
