This was first light for the Canon 135mm lens.
I decided to do 2 hours worth of exposures on the Rho Ophiuchus Nebula Complex.
It was very cold last Friday night and quite dewy.
I ended up taking 16 x 8 min lights, 16 darks and I applied 15 flats with the Canon 20Da set at ISO 400 and lens at f/2.5.
Final processing was done in PS CS3.
I'm extremely happy with this wonderful lens and look forward to more images from it.
Here's the original image:

Here's the reprocessed version (1.1MB)
