Here's a shot with my K7. Mounted on a Celestron CG5 mount, actually piggybacked ob a small refractor, but not using the refractor as the lens...
I'm not happy with the amount of noise in the photo, but I didn't have a remote, so wound up "gently" holding the shutter for 78 seconds. This weekend I'll try again - longer exposures, less ISO (remote shutter control)
ISO 1600, Tamron 17-50 lens, F3, 78 seconds
A shot of the Milky Way, looking south towards the horizon. This is a very dark site (rare these days) - almost no light pollution. The stars of Sagitarius can be seen on the left.
Comments always welcome!
