Dear all,
The framing was lower than expected, as I failed to raise up the Witch Broom higher to allow the nebulosity at the lower part to be reviewed.
The total exposure was way less, since no more exposure could be made when the object passed the zenith. EM11's guiding behaviour was poor at and past zenith.
Again, lazy processing without bias, dark or flat field.
Same setup as NGC281/Bubble and full imaging particulars are set out at :-
