Centaurus A now with colour repro and added time

I got quite a bit of colour and some Ha for the luminance I posted.
32 x 5 minutes gain 53, -10C blue
23 x 5 mins red, 22 x 5mins green, 12 x 5 minutes Ha

The camera is very sensitive and very low noise.

I got more exposure time last night. I added this to the image plus reprocessed it from scratch using flats as well.

It looks a little yellowish but I believe that is the correct colour as the data wants to go that way and also elliptical galaxies are often yellowish.
The image is also starting to show a hint of the shell structure and some odd shaped extended star halos at both ends.

I think this makes the Honders a galaxy imaging machine.
