A blog about a system to determine terrestrial albedo by earthshine observations. Feasible thanks to sheer determination.

Strange 'dragging' on at least the VE1 images - and yes, readout drag is up-down, not right-left.

Many frame dropouts. Temp. is between 4 and 5 degrees C.

B and V perform well at this very almost new moon, but VE1 and VE2 seem to need boosting relative to the bluer bands.

Wait, the VE2 is fine - it is the VE1 that is too low, as if it, in particular, wants to stick.

Noting that the external view of the VYSOS-20 position is the best for detecting the coming of Dawn.

VERY little scattered light from the BS tonight - even at very high airmass.

Very interesting comments on the low amount of scattering.

Most interested into looking at that, please do send me a frame!
