The ground track for this event was some 7kms wide and my house was located towards the centre, so I set up my 235mm diameter, 2350mm fl, F10 telescope and fitted my Canon 7D Mk II with a x0.63 Reducer/Flattener to give an effective fl of approx.. 1500mm at F6.3. This was so I could fit in the entire disc of the Moon.

The transit across the face of the (3/4) Moon was scheduled to last for 0.49 sec and I managed to record some 12 frames which I combined in CS6 to show the path of the ISS.

The more detailed, high resolution composite was taken through another telescope, using a 1920x1200 webcam at an effective fl of approx. 3500mm.

The transit lasted less than 0.49 seconds from my place, so it was a bit tricky choosing the optimum moment to trip the 7D Mk II which can shoot at 10 fps, whilst remembering to start recording with the webcam.

Cheers

Dennis

Absolutely amazing images!

I think you mentioned it before, but which software do you use for the prediction?

Thanks for all the comments folks, I appreciate them.:-)

I use the website at CalSky for notifications and then closer to the appointed date, I use The Sky X Pro (an astronomy planetarium program) on my PC to plot a path against the sky background. The Sky X Pro also helps with composition and choice of camera/telescope and can simulate the field of view.

I have found that I need to be set up nice and early so that the Moon is in sharp focus, the camera settings are locked in and then the fun begins. It is a freakishly fast event that rushes up to you and you can almost be paralysed with the mesmerising beauty of the dot of the ISS as it races up to the lunar disc. You need to snap out of it to trigger the camera as typically, these events are sub-second in duration!;-)a

Cheers

Dennis
