About this image

5 metre diameter (Spaceweather.com) NEA at 270,000 km from Earth, magnitude ~ 16.1 (JPL Horizons). Moving towards south-east, PA ~ 155 deg (top right of image).

Rapid motion of ~ 30 arcsec / minute meant that 4 minute integrations guided on stars didn't help with the S/N!

Nice!

Have you tried re-stacking on the asteroid? You will still have a line and the stars will be tripled but the SNR of the trail should be √3 times larger.
