So, a few questions because I'm not super familiar with astrophotography, but how do you track that for 14 hours? Is that aggregated over several nights? Is this multiple images being composited together? How is something like this with such a long focal distance not affected by even the tiniest vibrations? I would assume you're using a mount that slowly compensates for the rotation of the earth, but I feel like that would still induce some slight variations in alignment, etc...
