B33 - Horsehead short exposure experiment

It was time to make a yearly visit to the Horsehead, but the moon was going to be bright for half the night and I wanted to see what would happen with Alnitak if the exposures were shortened. My theory was that bright stars would be less disruptive, less sky glow from the moon, but a large amount of short exposures would still pull the dust.

I think it was a 50/50 successful test. Gradients and Alinitak were diminished, still can pull some dust details, but the dark cloud that flows from the horse to the flame just stayed dark with no details I could pull out of it. Longer exposures can pull those details out from my past experience.

Just wanted to see if a ton of short exposures could make up for longer exposures, but it appears not in all cases.

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.
