Approach of Near Earth Asteroid 2003YT1 to Polaris, 02 November 2016
An article in Astronomy Now highlighted the passage of NEA (Near Earth Asteroid) 2003YT1 close to Polaris on 01-02 November. The sky was clear so I captured images with static cameras.
I used a Canon 60Da camera at ISO 800 coupled to a Megrez 90 mm, f/5.2 refractor on an HEQ5 mount to record 341 still images during the period 23:59:47 - 02:58:42 (UT). Each image was of duration 28 s and consecutive images were separated by a gap of 2 s. The video below shows two sequences produced from the images. The first is a movie formed from all 341 stills. To create the second, I combined 10 frames to make trailing more visible then advanced three frames and repeated the process, i.e. I combined frames 1-10, 4-13, 7-16 and so on, creating 111 images in all.
I also captured images with a Canon 50D with a 50 mm, f/4 telephoto lens, but these were not so impressive. I attempted to capture images with a 200 mm, f/10 Celestron Edge HD Schmidt-Cassegrain instrument. Unfortunately, the very small field of view of some 10 arcminutes made the task of finding the NEA very difficult and I was unsuccessful.
