One more bug report with All-sky PA (including the most recent 1.9.1 (27) build - After you finish the align and the fireworks play, the fireworks never stop playing. This is distracting when you try to do a second all-sky PA (as suggested by the app), as the fireworks are playing on top of the alignment reticle. Can the fireworks stop playing after maybe 15 seconds, or once you start a new PA?
Side note though - this experimental feature worked great. I had no view of Polaris so I had to try it, and after 2 all-sky aligns, I was getting 5-min tracked subs with sharp round stars.
