M83 - sorry - first time for me!

A clear night!

Here is M83 LRGB with 40mins L and about 30 or RG and B with the latter binned 2x2. 127mm triplet and Opticstar 145m. Not a classic I relaise but I am quite pleased - this is only the second time I have attempted LRGB imaging (Sydney light pollution!) and I am far from good at the processing required plus I had many faults (flats need to be re-done, which is why the image shows clipping (avoid visible dust bunnies), gradients are present and I lost most of my L data by leaving binning at 2x2 and overexposing as a result!)....still as it is only my second galaxy image so I am quite happy...
