During the eclipse I had the presence of mind to take some images for a HDR shot. I saw David Houghy's shot tonight and immediately started working on mine. Not as good as his but I am happy all the same.
David, no stars in my images. I guess such short exposures of 1.5" is not enough for the RC to produce star. I was only using ISO200 too, so that would have had an impact on the prospect to get stars.

mmm I was using ISO100 and managed to get some? maybe it was the 2.5 2 second shots that got them and not the 1.5?
I'm fascinated by the dynamic range of eyes. I was looking at the Moon through binos and I could look to the fully illuminated side and see all the surface detail, then swap to the edge of the limb in shadow and immediately see the reddish tinge and the surface detail on that shadowed side.
David I am not sure why. What F ratio were you working at? It does seem odd, I have looked pretty hard over the image and not see anything. Oh well next time.
Eric, I was telling the people we were with about the dynamic range of the eye compared to the camera. The camera cannot compete. Just like how a solar eclipse looks and yet one can never show what your eyes see with a camera.

Paul, the scope is f7.5 - 127mmm at focal length of 952mm
Paul,
I have just processed two earlier sequences - one at 9.28pm which was only 10 minutes short of the first sequence i processed and the other at 8.46pm. the 9.28 sequence only shows one star - and that is "just" shows it. Same settings. I think it really came down to the 2.5 second long exposure that gave the stars - and that was at the maximum coverage, so 10min really did make a difference. if only you had gone that tad longer?
