Hi. I was lucky to catch a bright slow moving fireball this morning on both the DSLR and ASI120MM with 150 deg fisheye lens. On both imaging devices, the fireball goes for over 1 min. I can see the remaining tail the in subsequent frames after the initial capture. Here is a TL also. The fireball is in the last 3 frames.
Cheers,
Steve.
