Just back from Guam for the annular eclipse which was a weather iffy choice but it worked out well with clearing skies the day before that persisted through and beyond the eclipse. The Tumor bay location was very close to the center line with slightly more than 3 min maximum. This yielded nice symmetrical annular images. I am not sure I have ever been closer to the center line for any eclipse. I observed from a high floor at the Hyatt Hotel which had a great view over Tumon bay. My Q configuration was my duplex with a piggyback mount to which I mount a televue solar finder and an axial Nikon D850. A drive isn't necessary with exposures in the thousandth of a second. The mount shown is a lightweight Gitzo traveller and a manfrotto gear head that makes tracking easy and solid.
