Do you know enough about the characteristics of the telescope and camera to estimate the angular size of the object? Can you estimate more precisely when and where you took the photo, and where in the sky the scope was pointing at the time?

It was taken in San Francisco. It was taken exactly an year ago (2015-01-20). I don't remember the direction but I would guess it was pointing East-South East - that's the only direction which has a clear visibility from where I took this.

Could be an unsharp image of a lamp, an aeroplane, the Moon, a star, a planet, whatever. I don't think it's iikely that this can ever be identified uniquely.

1/20 was wednesday. It was raining down in San Jose that night. Could be a plane coming in through a low cloud layer or a drop of water on the lens distorting some other ordinary light in the sky.

Could anyone identify what I am looking at here?
