Gday, couple of pics of NGC5128 and NGC5139 under the glorious full moon exposure time was limited to 120seconds and both where 5 frames combined {@640ISO/D70}.While I was focusing I forget to switch back to RAW files with the Cent A shot and didnt get any dark frames Jupiter beckoned after midnight so didnt follow up with the DFs.
Yeah Paul seems to happen when I shoot through the SCT, maybe the IDAS filter adds something plus at ther time of capture I was going to experiment with the white balance settings on the camera.Other then that its pretty straight forward , the frames are aligned/combined in Images plus , run through digital development a little mask processing and pixel math.
Both of these shots are fairly severely clipped. You say you used ImagePlus Digital Development. If you used AUTO that can result is this clipping, making it very difficult to correct any colour balance with later processing. If this is the case, check out my article to see how to fix it.
