Not all evenings are good for imaging, and not all seemingly good evenings end well.
Last nigh was an unlucky one.
Started well, with a clear blue sky, it turned into a night with crazy turbulence and at the end completely cloudy.

So waiting for the "main target" here the "focus test" target, the only loot for this unlucky night.

only a handful of shots with a seeing over 5 arcsec
