As soon as the moon set I started shooting the Iris Nebula. I was able to get about 3 hours worth of data. If wind had not started blowing around 3 AM, I would have pretty much doubled the total integration time… too bad.
I was surprised at how much dust I was able to capture with only 3 hours of data. It is somewhat challenging to process especially when keeping noise under control.
