Omega Centauri is the largest globular cluster in the sky and contains about 10 million stars, but it's generally considered a southern hemisphere target since it's at -47 declination. It was right at the meridian for me while waiting for it to get completely dark out, so I tried shooting it at just 9 degrees up. Had to do short exposures without guiding, because even the dim flashlights of the other campers with me would overwhelm my guide camera. Captured on June 7th, 2024 from a Bortle 3 zone (Deerlick Astronomy Village)

They at least have an ISS live stream going most of the time, but it's pretty boring at night or when they lose coverage

Wasn't expecting much with the last night's geomagnetic storm, but seeing the aurora come in on the camera was definitely an "oh shit" moment for me and my wife, especially when it got overexposed. The initial burst in the gif was very noticeable to the naked eye, despite our light pollution. Sadly it died down a bunch, but seems to have come back (although not as strong) after 3am (video timestamp is in UTC). Tonight definitely wont be as strong, but I'm hoping the camera might pick something up on another timelapse. Captured on May 10th, 2024 from Atlanta, GA

(probably) Better quality version on youtube
