Hi Mike

For a Lunar near miss, at a FL of 600mm the FOV is around 2 x 1 ½ degrees so the HST should pass through this field in less than 10 secs, so I’d be sure to give an exposure of at least 10 seconds.

But, this would flood the FOV with light from the grossly overexposed Moon, so I’d plan to switch to Jupiter instead and take an image with Jupiter in the FOV, although this too will be grossly overexposed.

Cheers

Dennis
