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!
