NGC 253 2-frame mosaic

Hi,

After a promising start to the night I'm a little disappointed how
this turned out.
Seeing was very good at around midnight for the start of frame 1
(left hand end). I thought the focus was spot on but analysing the
frames afterwards showed a little softness of stars.
Hard to spot on the remote desktop laptop inside
Camera was turned so that the plane of 253 suited the framing of
a 2 set mosaic. I thought 2 would do...turns out I was wrong

The hardest part was to normalise levels between the two.
The join is pretty obvious.
Seeing had gone downhill after about 2am just as set 2 was finishing.
