NASA's Wide-Field Survey Explorer telescope, currently orbiting in a hibernation mode in case any future proposals are accepted for funding to use the telescope (having expended its cryogenic coolant, its utility is now limited). Tracked with an 8" LX200 and modified Samsung SDC-435 camera @ f/3. 1/60 sec exposure, AGC low.

Introducing SatTrak, a free Python program for automatic tracking of earth-orbiting satellites with a GOTO telescope. This program will be compatible with the Meade LX200 Classic and ASCOM compatible telescopes which can use the "MoveAxis" method in ASCOM. Stay tuned for details on where to go to get this new program.

1.7 hours of footage. Recorded just hours after its close approach to earth with an 8" LX200 classic and MCHP at f/3 (14 second exposures). This asteroid can be likened in size to the starship Enterprise, possibly as small as Kirk's Enterprise, possibly as large as Picard's Enterprise-E. A few power lines and satellites pass through the field of view during the video.
