I was inspired by Space's Ceres animation (http://www.iceinspace.com.au/forum/showthread.php?t=42188) to give the dwarf planet a go. I took 2 frames every minute for about 140 minutes and made an animation below with every 12th frame - I had to discard many frames to provide a smooth animation due to clouds rolling past regularly!
Info:
Canon 450D on unguided EQ6 (EOS utility for capture)
55-250mm f/4.0-5.6 kit lens at 250mm
10 sec exposures at ISO 200, ICNR - 24 frames in total
Aligned/cropped using homebrew MATLAB code (needs a bit of work)Improvements: If I could see more than a quarter of the sky (can't see East nor West), I would have been able to drift align better and prevent the trailing. Also I probably should have used a higher ISO setting - my laptop monitor is so bright it makes my dark images look 4x brighter than they really are - bad when I transfer the images elsewhere and find they are actually dark!
