While waiting for narrowband targets to become available, I just pointed at Comet C/2011 L4 PANSTARRS and let it go for nearly four and a half hours last night.
Luminance – 130x120s binned 2x2

Collected with Maxim, calibrated, registered, normalized and saved to jpegs with CCDStack. Avi created using PhotoLapse3 (http://home.hccnet.n...photolapse.html). Title added using Adobe PhotoShop (there must be a better way).
