I'm hardly game to post a Centaurus A after Rolf's 120-hour effort last year ... but I was quite pleased with this one, 2 1/2 hours 90:20:20:20 LRGB, colours binned 2x2. Atik 383L+, 10" SCT at f/6.3. It's an interesting galaxy.
Here's a link to the full res version.
{Edit: uploaded reprocessed version with less sharpening}
Cheers
