Insufficient Superlatives – Again!

We lucked out for the 2017 eclipse, but this time the eclipse came to us and we lucked out again! I was on edge as high clouds approached at eclipse time, but fortune favored this neophyte astronomer and a small family group watching from our yard in northern New York. I took 3 exposures every ten seconds throughout the event. Here’s a preview hot off the press. More as time permits. Traffic stretched for miles as the eclipse concluded, but this time we got to watch rather than sit in it!

Update: These photos were taken through a Canon zoom lens set at 250mm and f8, and with the addition of a 2x expander for a total focal length of 500 mm. It’s an APS-C format sensor. There is minimal or no processing of these images…there are just too many to go through right now. But I hope process them bit as time permits to pull out more details.

The camera was piggy-backed on my CPC-800 telescope to take advantage of its tracking mount and equatorial wedge. But once again I struggled with the notion of taking images directly through the telescope. It’s field of view is a little too narrow and I didn’t want to crop the diamond ring and corona. So, the Canon lens it was despite its relative lack of sharpness compared with the telescope.

A bit after first contact.
Here’s a shot showing the corona
HDR Corona – combination of exposures: 160th, 100th, and 60th of a second. Meant to bring out detail in the bright and dark regions.
Solar eclipse image shows the sun nearly completely covered, but not quite. A tiny arc of the sun is uncovered to produce what looks like a diamond ring.
“Diamond ring” just as totality ends
