I used two "targets" for testing, sample grey card and a small stamp. Both were imaged with MF Nikkor 55/2.8 lens attached. I ajusted gray card exposure to get three "spikes" visible on histogram. I still need to play around with camera settings, to get a best estimate for first astro imaging session.Camera is equipped with 1.25"/C -adapter. In my William Optics SCT grayford focuser 2"-1.25" adapters brass compression ring is bit too wide for 1.25"/C adapter. Hopefully this does not cause any problems "in the field". There is another ring (C/CS adapter?) also in camera, this I do not need in my imaging setup.
Now I only need clear skies, weather forecast looks a bit more promising. Clear skies were estimated at night between friday and saturday...
