Description

This mosaic project just gave me a timeout on RGB mosaics 

After collecting data almost twice (SGP once and once more in Nina), I thought I had good amount of data, but with the overlap issue (posted in my 4 panel Rho mosaic), I ended up shooting all 8 panels in Nina. At that time after several tries, I stitched 4 panels of the Rho region after trying in APP and PI. I had moved all the data out to a USB drive as I was drawn to trying mosaic versions almost each day. 

Anis recently posted a 17-panel version of Rho (bless his heart and his processing pc) and it gave me a motivation to try this one more time (or several times again to reach that one more time). In the end, PMM helped here. I ditched the last two panels, to the right of Rho as they were shot when the moon was up and messed up the whole image

6 panel mosaic. Each panel was little over an hour. 

Hope you like this result. Clear skies!
