Thanks Gents, I'm very happy with the result of it all. I am living here in Cavan, my home is located in very dark skies at night
My set up is simple - I took this shot on August 15th under very clear skies, this is a stack of 25 x 4minutes exposure and 15 dark frames at ISO800, f3.5 using my canon 40D (unmodified) and my 24-70mm L lens at 32mm, all this was mounted on a very accurately polar aligned astrotrac mount.
Processing was with Photoshop just apply a little median filter which brings out the dust better.
As for Rho Ophiuchus - it's on the list
