C/2021 A1 (Leonard) 2021-Dec-27 Jan Hattenbach

Here is las night's (Dec. 27) mosaic. Same as before, two 50mm exposures combined. Only this time my timer broke down, so exposure times are not exactly 180s.

The tail is fainter overall than 20 hours earlier, and more diffuse far away from the comet. Note how the "knot" closest to the coma has moved further out.
