About this image

Time stated is midpoint of capture and is UT. Motion blur due to comet movement over 610s.

Not all acquired frames were stacked, hence the mismatch between duration of capture and integrated exposure time.

David,

Nice to see your variety of images. 2012 TC4 will be about magnitude 13-14 at close approach but moving up to 13 degrees per hour, I look forward to your movie clip of TC4. I have never tried to image something that faint moving that fast before so it will be an interesting challenge to see if one can get something that is not a streak.

Cheers, Mike
