This image is Centaurus A taken with Tak FSQ106ED with the 1.6X Extender fitted. Taken with QHY9 and QHY filters.
50 minutes of each RGB.
The problem I seem to be struggling with is the red channel doesn't seem to align well and I end up with some form of field rotation between the colours. For the life of me I cannot seem to get the 3 channels to line up correctly. Any ideas or suggestions would be appreciated.
The other thing which has me guessing is the small diffraction spikes on the brighter stars. Nothing used to generate these and I wonder if it is something to do with shutter operation.
Anyway here is the image.
