Rho Ophiuchus

This was imaged using a astro modded Canon 40D through a 150mm prime lens, piggy backed on my SCT, so tracked and guided using my 80mm frac as a guide scope.

Total Exposure was 2 hours, consisting of 30 x 120s, 15 x 60s and 30 x 30s subs at ISO800

With in we can see Rho Ophiuchus, Antares, M80 and M4 among the gas, dust and nebulosity.
