Rick Johnson's great video reminded me that I forgot to post mine here. The first night, I imaged it using my 12" RC on a Paramount MX+ tracking on the asteroid. The second night I imaged it from my city driveway using a 90mm refractor tracking on stars through thin clouds. The only processing was adding the description logo in PhotoShop and combining into a video using Photolapse3.

Your first video really gave me perspective of our place in the universe as Florence travels across the nights sky so quick.

 

In your second video Florence is so bright. It really got me thinking of how close (4.4 million miles) Florence has come to our Earth. At 2.7miles across good thing its a fly by.

 

So cool that you captures this high speed near miss. Great video and thanks for sharing it with us all.

Your movie is more what I wanted to do but even in a 10 second exposure, only a few stars were visible due to thick smoke from BC fires.  Moon was an eerie dim red color as was the entire landscape.  Still, that way last night for a while then it cleared some just as a ground fog moved in to replace it.  Sky gods have it in for me it seems.  My camera's download time of over 4 seconds when binned 2x2 makes a short exposure jerky due to the long gap that's less noticeable with longer exposures.  Still, with the wind, I'd have gone that route but for the thick smoke.  The sky is white today with it so thinning but has a long way to go.
