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

Getting the setting Moon in clear skies.

Plenty of 'filter stick' and it comes in sets - when we change filters the shutter 'unsticks' and we are good for one set of images, then we change filter and there is the chance that we get good data or bad data.

We also see a periodic shifting of the Moon inside the frame. Either the JPL table of Moon positions is slightly bad, or the interpolation is done.

Question: Is the table of Moon positions interpolated or do we go for 'nearest neighbour'?

See the telescope and the Moon!
