Perseid Meteor Shower Watching Success but Photography Fail

For this year's Perseid shower, other things got in the way of getting out to a dark sight to view it or to even be up watching pre-dawn on the 12th but that evening we sat out in the back yard with two of our grandkids, Jack and Harper, to try and catch at least a few bright ones. 

The good news is that we did each see at least one. The bad news is that was before I set up my camera to capture this time lapse video. The other challenge besides the light-polluted skies of Dallas are how many other lights there are in our back yard. The ever-changing color of the neon clock in the kitchen, visible through the back door or even the time one of us went to the bathroom (the window next to the back door) were the least of the problems. I'd turned out our patio LED light strings and the solar path lights but neighbors to the west and southwest have a lot of yard lights on all night. This video represents from about 11pm through about 3am and it was never truly dark out there. 

Normally, I would have had the camera at about ISO 4000, f/2.4 and shooting 20 second shots. The best I could do without blowing things out was ISO 400, f/2.8 and 8 second shots. That was still enough to catch stars rotating around Polaris and should have caught any bright bolides. Sadly, the only lights in the sky besides stars were aircraft going to and from Love Field and DFW.

I had been tempted to go out east of Dallas by myself about 5am to see if I could shoot the Perseids from a darker sight. Glad I didn't bother as the clouds rolling in would have spoiled the view under even the darkest skies.

Total Eclipse Time Lapse

This is a first pass attempt at creating a time lapse video of the eclipse using wide-angle shots taken in Marshall, Missouri.

The entire first half of the eclipse was obscured by clouds with the sun just peeking through at totality. Ironically, for most of the end of the eclipse (starting about 15 minutes after totality ended) the Sun was shining against a clear, blue sky.

Notice the umbra moving in from the right and then moving off to the left. In mid-totality, notice how distinctive the Sun's corona is, even as small as the Sun is in the overall image.

Not entirely satisfied with this, yet, but sharing while I continue to work on a "final" version.
