Description

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.
