Here's my latest effort - Centaurus A in LRGB, captured in one night since the weather in Melbourne has been shocking lately. Have swapped out my imaging camera from the ZWO1600mm pro to the 183 and so far the microlensing issues I was having when using the 1600 have now gone.

Image details:
L - 60s x 81
RGB - 60s x 34 for each channel
Gain 53, -15deg, calibrated with 75 x dark, flat and flat darks
Equipment details:
Skywatcher Esprit 100
Saxon AZ-EQ6 GT
ZWO183mm pro, 290mm mini and OAG
Lakeside Astro Focuser
Astronomik Deep Sky RGB and CLS CCD for Lum 1.25" Filters
Pegasus Astro USB Hub
Hitec Astro Mount Hub Pro Compact
Optec Flatman light panel for flats
SGP Pro for image acquisition, PHD2 guiding, Sharpcap Pro for PA and Pixinsight for calibration and processing.

Thanks, I've learned the hard way myself and find I now check out images on Astrobin with similar equipment as mine to get a better idea of exposure times. Lately I seem to find if I stick to a mean ADU of 1000-1500 for LRGB then my stars come out ok.
