OH NO Centaurus A

Suffering a serious withdrawal from imaging due to smoke and bad weather I grabbed the chance last night to shoot a few frames of Centaurus A.
8 X 10minute Luminance images of this Galaxy, Taken with:
QHY9 Mono CCD with Custom Scientific Lum filter Through my Tak FS102 with the reducer/flattener fitted. It could probably have done with the extra focal length without the reducer but ends up with a much flatter field and quite a few stars in the surrounding sky.
When time and the weather permits I will take some RGB to add to this but until then this is the best I could do.
The image started out as 10 X 10 min images but some small glitch in the guiding caused me to discard 2 of them. The image has been fully calibrated using Darks Flats and bias frames.

Comments welcome.
