Total Lunar Eclipse 2015-09-28 ~0305 UTC

Image sequence calibrated with bias, dark and flat frames. Aligned on the details of the moon in IRIS. Colour calibrated with a G5III star in the field. Wavelet adjustment in Registax5. The original stacked image clearly shows the moon's motion relative to the stars. In order to have untrailed stars, a background was generated with alignment on stars and then stacked in IRIS. The moon's position with respect to the stars is accurately the same as the first image of the sequence, i.e., at ~03:05 UTC. Unfortunately the EXIF time has not been calibrated until a week later, so the precision is estimated to +/- 1min.

The adjustment of wavelet was stretched less intensely so as to show a visual view of the moon through a set of binoculars. Low clouds moved away, leaving only some high clouds.
