Rho Ophiuchi Region

To all,

Here's another image I took early this year using the Canon EF 200mm f/2.0L.  As usual, to improve stars in the corners, I stopped down to f/4.0.  Given the limited time and low altitude of this region from 45N, I was limited to just thirteen exposures.  I used a modified Canon 5D2 at ISO 800 with exposures of 480 seconds.  This was taken in early May before determining ISO 1600 was a better compromise between total time and noise.

Thanks for looking,
