Focusing the 907X in near darkness is indeed a problem. At some point the magnified view just goes black.Some night and astro shots. The main challenge was focusing as there is no live-view gain that I could find in the settings of the 907x. Let me know if I missed something. I'm not 100% sold on the processing yet -- I'll likely do a bit more work on these files before they are final-final but I wanted to share nonetheless. XCD 30mm.
