Hi Carlos,
If you look at the top border you can see a glow as if some bright object off frame was spoiling the picture. That comes from inside the camera from its own electrics. I think there is a way of turning it off in the software and or taking better dark subtraction frames to neutralize the effect. Either way I was in a hurry in the end too get something on by midnight. You might notice to some blue and red specs which are hot pixels also in the camera residing on the actual CCD chip. I have mostly used the Dsi as a guide camera and chose to use it last night because of its smaller field of view and its ability to stream images quickly which I thought might be helpful. Alas looking for asteroids is,like finding the proverbial pin and its a skill I will have work on.
Cheers
