Lunar terminator time lapse taken on 24th-25th February 2018 (between 20:19 and 02:21). The Moon was waxing from 67% and 69% full. The seeing was good for the first 2 hours then deteriorated as the Moon approached nearby houses. This leads to a drop in detail.
The animation is of the lunar southern region including craters Tycho (top right), Clavius (bottom) and Longomontanus (middle left). Longomontanus is displaying the greatest effect of the moving terminator with its central peak appearing out of the darkness and the shadows of the crater walls forming a shrinking arc around it. New features begin to appear on the terminator as well to the south.
Equipment: Skywatcher Skymax 150 on an EQ5 pro mount. Canon 550D in movie crop mode at ISO100 with a Baader fringe killer filter. I checked the focus of the scope three times during the night and each time very little adjustment was needed.
Each frame is a stack taken from a 5 min video (at 60fps). Each video was recorded with a 5 min interval so as not to run the memory card out of space. Aligning, stacking and processing done with Registax 6, decompressing and final frame alignment done with Pipp. Some of the final frames were automatically colour re-balanced which lead to a bluish hue, I should manually re-correct them...later.
