Part of a larger mosaic, this is panel 2 - the main Rho Ophiuchi area of nebula and dust
HaLRGB 120 60 60 60 70 for a total of 6 hours 20 minutes.
One of about 10 panels so far. I think I will be needing some advice about how to stitch them together. Whether I make one big lum, R, G and B or stitch individually processed panels? If I can put them all together it will end up being over 3.4 billion pixels.

Also out of interest there is a great You Tube video about largest stars and Antares is right up there. It is absolutely huge, many many times larger than our sun.
