Best viewed at 480p. 1 hour time lapse of tracking NASA's Solar Dynamics Observatory. SDO orbits in a geosynchronous (though not geostationary) orbit. Tracked with an Orion ST-80 piggybacked on an LX200 Classic. Recorded with an MCHCP at 128x sens-up. Tracking performed with Brent Boshart's Satellite Tracker.

ISS and Resilience were recorded flying by Jupiter on 11-18-2020. Captured with an 8" Meade LX200 Classic in alt/az mode @ f/20 with a 2x barlow. Recorded by a Blackmagic Pocket Cinema Camera 4K with a 1/500s exposure at ISO 25600. Frames were stabilized by custom software. ISS was tracked by my open source SatTraker software:

Analysis of the satellites most at risk of a collision with asteroid 2012 DA14 in February 2013. The risk of an impact with any satellite is extremely low, but if it does collide, it will be with one of these.
Monte Carlo solutions calculated with FindOrb, solutions displayed and compared to satellite positions using ORSA.
