NGC 4945 Tweezers Galaxy ( Golden Coin Galaxy )

This my second attempt in 2 years to capture this dim 9.5 magnitude galaxy in the constellation of Centaurus
Discovered by Scottish born James Dunlop at Parramatta Sydney in 1826 this barred spiral galaxy is often compared to our own Milky Way. Located about 11 million light years from earth
Captured last night between 8.30pm and 1.00am

8” f5 Bintel newt on an EQ6- R mount
Canon 600D stock with Baader coma corrector ( no filters )
Orion 60mm guide scope with helical focuser and ZWOASI120MM-S guide camera
ISO 800
62 x 3minute dithered guided subs
30 x darks
PHD2 guiding at 0.80 to 0.90 arc sec error
Medium dither every sub
Goto and tracking EQMOD, StellariumScope and Stellarium
Frame focus and capture BYEOS
Stacked in DSS

Any ideas ?
