First Elephant's Trunk

I went out on Wednesday to shoot this. It was the first clear night with no moon out in the last 3 months at my house in NW Ohio. Well, the only batteries I forgot to check were my SkyGuider Pro's batteries, and after setting up and getting polar aligned, I switched the tracker on and was greeted with about 3 seconds of low battery flash, and then a totally dead battery.

So, Thursday night, the forecast was okay, at least for a couple hours, and the clouds were definitely up there, but I was desperate to at least try.

Only ~1.5h of exposure time, and with pretty poor transparency.

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.
