My first attempt at building a mosaic so it would be good have a critical appraisal please re: any improvements or suggestions. I chose the SMC as it is well placed at the moment to capture a good amount of data each night. There are some good objects coming into play now which I would like to capture some four panel mosaics on, hence the practice runs on the SMC.
This is a two panel image with HaRGB. Approximately two hours of data per filter per panel. The area is the north east section of the SMC. The panels were assembled in Pixinsight and used tools such as the "Mosaic by coordinates" script and the GradientMergeMosaic process.
In my first attempt I tried assembling the R, G and B filters into separate two panel mosaics and then combing them into a single panel RGB. This didn't work as I finished up with a nasty colour gradient. I then tried assembling the RGB in each panel first and completing DBE, PCC on each before combining and this seemed to work ok.
It was in interesting learning experience going through the process I have to say. The image files finish up being VERY BIG
and the PI processes take a while to run through the hoops. And this is only a two panel mosaic. It must be quite a struggle throwing around the panels for larger mosaics.
I've set up a shared dropbox folder with a TIFF (54MB), PNG (26MB) and JPEG (11MB) version of the image.

Again, let me know of any thoughts and thanks for looking.
