Hi Peter, you can image these with the c 9 25, but even with a 0 7x reducer you will have three times the focal length I'm using here so only a small area of these can be captured.Tracking and guiding at such focal lengths will be ever more critical for a decent result. I find guiding at 585mm enough of a challenge.
