Asteroid 2014 JO25 recedes from view (20 April, 2017)

Asteroid 2014 JO25 ziping along with the scope tracking on the asteroid (the asteroid is the dot near the edge). 20 x 60 second luminance exposures with iTelescope T11 stacked and aligned in ImageJ. Imaging starts at 9:05 UT (3:05 am local time 20th) Click to embiggen.Animation of the same 20 x 60 frames (click to embiggen for animated asteroidal goodness)

As Asteroid 2014 JO25 recedes from earth I was able to get some more images and animations. By the time I took the above images with iTelescope T11 in New Mexico, it had moved far enough away that I could track on the asteroid. Still moving at a fair clip and the stars are trailed.

Asteroid 2014 JO25 zips along receding from Earth with added satellite trails (the asteroid is the dotted line through the centre). 20 x 60 second luminance exposures with iTelescope T14 stacked and aligned in ImageJ. Imaging starts at 3:05 UT (9:05 pm local time 19th) Click to embiggen.Animation of the same 20 x 60 frames (click to embiggen for animated asteroidal goodness)

Earlier in the UT day from T14, also New Mexico. Asteroid is moving too fast to track.

Asteroid 2014 JO25 near galaxy NGC 4710. 7 x 120 second luminance exposures with iTelescope T13 (Siding Spring Observaory) stacked and aligned in ImageJ. Imaging starts at 11:00 UT (9:05 pm local time 20th) Click to embiggen and see more galaxies.Animation of the same 20 x 60 frames (click to embiggen for animated asteroidal goodness). Cloud comes over in the last frames.

Finally an image from telescope T13 at Siding Spring Observatory in Australia, choosing to track on the galaxies rather than the asteroid for a prettier composition. Clouds have ruined any chance of me seeing the asteroid with my own instruments.
