Title: Eclipse
Post by: Buster's Uncle on August 21, 2017, 08:02:32 PM

Aprox. 1:40.
(http://alphacentauri2.info/MGalleryItem.php?id=2310)
I couldn't see what I was doing, so no more pics of the sky.

I ran indoors and drove a nail through a piece of plywood:

And you can see a little projection on the paper at the bottom.

I gotta go get some shots of the horns pointed the other way before I process more pics...

I went outside near maximum and just stared at it (safely, with appropriate cardboard glasses by a reputable manufacturer purchased last year). And then again about 20 minutes later. Coworkers shared the extra glasses, except those that were busy/didn't want to. I'll go out again in a bit, maybe try to catch the end.

Post by: Buster's Uncle on August 21, 2017, 08:36:36 PM

As you can see, badly, in the OP, the Sun was behind a cloud - enough to make the early shadows dim and fuzzy, but not thick enough cover to photograph successfully.  I'd have sworn it had a little bit out of it already 15 before, but it's not like I could really look.

I wish I had a better-focusing camera for this -and everything else, actually- but I got the nailhole projector better focused on the paper as it went on, so fingers crossed as I look for not-hopelessly-out-of-focus shots between running out to get shots of the backside of the event in progress...

-Unfortunately, the camera thinks all shots were taken at 1PM, 2010 - so no more timestamps, I'm afraid.  It peaked at approximately 2:39 here.

Wereabouts is that?

Title: Re: Eclipse
Post by: Buster's Uncle on August 21, 2017, 08:45:28 PM

The sun is approximately southwest at this time of the day, and I was facing approximately west to take the pics.  Naturally, the projection is inverted...

Near DC, probably only 82% or so.

Title: Re: Eclipse
Post by: Buster's Uncle on August 21, 2017, 08:59:19 PM

Allegedly 97% here at the foot of the NC mountains, head of the Catawba River valley.  It got nothing like night, here, but was creepy dim for a sunny afternoon, worse than a middlin' overcast day.

-Taken around 2, these pics of the shade of the pecan tree get a heck of a lot more impressive later.

Facing roughly towards the sun:

They're only just faintly beginning to show a million little crescents here, and I've cranked the contrast for clarity.

Title: Re: Eclipse

10 minutes or so later, definitely getting unmistakable...
(http://alphacentauri2.info/MGalleryItem.php?id=2317)
Makes it look like the shade of a palm tree.

Took my last shot about 20 minutes ago - only a little, small, bite out of the disk left then, about an hour and seven minutes past peak...

Title: Re: Eclipse

I wish I'd taken notes.  Just jotting down times when I took a pic would help me sort/remember...

I always take multiple shots of everything, never having worked with a single digital camera that was reliable about focus.  That's why the range of sizes and some variation of angle despite trying for some consistency facing the same way - shooting at different distances hoping for one in focus.

I thought you had 97% totality?

Never thought about checking the shades of objects.

Title: Re: Eclipse
Post by: Buster's Uncle on August 21, 2017, 09:27:49 PM

I'm still back at a half hour before peak, and processing bad photos as fast as I can...

It was REALLY hard to see the crescent at all at peak.  I doubt any of those photos will be usable.  I'd say 97% is pretty close.

Young man, either I'm a genius -I am, and Uno, too, but that's neither here nor there- or you just gave away that you never saw an eclipse maybe as much as 50% with any trees in the vicinity.  I think this is the most eclipse I ever saw, but it gets pretty obvious somewhere over a third occultation, ISTR from a couple eclipses in my youth.

You rarely notice, but leaves project the disk of the sun all the time - once in a while if you're in, say, a dark tin-roof shed/barn on a stormy day, you'll see a little pinhole in the roof projects a perfect image of a thin cloud passing over the sun - but otherwise, it's always round beams of light and we just don't notice...

Title: Re: Eclipse
Post by: Geo on August 21, 2017, 09:45:07 PM

I've seen two totatilities and I think two or three partials over my lifetime. During the totalities the Sun was either still too low to see decent shadow shapes (on a beach in the morning in Australia) or the weather was too louzy (France). Same for my first partial (early evening in the back yard of my parents house in the seventies) and my last (dense clouds, you could safely look at the Sun with the Mark I eyeball).

Anyway, you can start making preparations for 2024 now. The eclipse path should be roughly southwest to northeast then. :D

Title: Re: Eclipse
Post by: Buster's Uncle on August 21, 2017, 09:48:50 PM

Okay.  -No nagging me 'til two weeks before, hear?

---

Around 2:20, maybe.

(http://alphacentauri2.info/MGalleryItem.php?id=2323)

I didn't crank the contrast for this one.

I'd typically take about three shots of the projection at different focal lengths, then get up and take a few shots of the pecan shade...

Lorizael is in South Carolina today, BTW, and saw totality, weather permitting, with far, far, better preparation than I, and serious astronomy training, to boot - Geo, am I correct in thinking you join me in begging him to post much better pics?

-Am I, sir?

Title: Re: Eclipse
Post by: Unorthodox on August 21, 2017, 09:49:58 PM

You could split my pics into here if ya like. 

this is my third near-total eclipse, and the first time I've seen the tree shadows, but I was REAL young the first time, and the second, it was near sunset here, so just not a good timing.

I figured you already had a thread in a more sciencey section, and I was waiting for the link to turn up here before I posted that here and save you the trouble of merging threads. I saw it on Twitter.

As I expected, it was overcast here and I couldn't even tell where the sun was when I went out to check the mailbox, after the rain stopped and about  10 minutes before the eclipse. Looked great on tv in the various places.  It was kinda like that the other two times in my life I can remember a partial solar eclipse.

Let me see if I can find another image I saw today on the net...

Scroll down to what is currently the 3rd and 4th images ( the black and white images ). It's a satellite view of the black shadow passing across the country. Pretty cool.

If this were a ghost hunter tv show, it would be conclusive proof of a demon.

I was mainly observing with glasses and through my binoculars with solar filter attached. Took a few pretty terrible photos with my cell phone camera. Here's one of the partial with some solar filter film taped in front of the lens, and one of totality where, because I don't know how to take photographs and was overwhelmed by the whole thing, the settings are such that the corona nearly washes out the moon.

Post by: Spacy on August 22, 2017, 01:54:49 AM

Here are a couple from Detroit area.

First, unfiltered - you can see the blue dot below the sun - that is the moon as it starts its crossing.
2nd - filtered - you can see it as it is almost over.  Camera focused on the filter, not infinity, thus a bit blurry.

edit: they are 90 degrees off in the post.  Bottom is on the right.

By this point, I've gotten better focus of my projection, but it's getting thin enough to be increasingly difficult to make out, let alone get the camera to focus on...

Pity the camera couldn't catch how creepy-dim the world was getting - the light angles and horizon were just all wrong for dawn or dusk, and it was tickling a semiconscious unease...

(http://alphacentauri2.info/MGalleryItem.php?id=2344)

I must've put the camera down for 30 seconds or something - the crescent didn't flip instantly, but it was really dim, and you can see I was right about how crappy the phots were going to turn out, so I guess I just watched and looked around at the weird world for a bit.

---

How did it get this late already?  I'm going to bed; the pictures of the crescent of projected light get incredibly crisper again as it suddenly started getting a lot brighter out fast, and I'll post cleanup pics tomorrow - but you've seen the 97% now, if badly; the rest is just epilogue...

Not really. I like to live in cloudy places on account of my Celtic complexion, so it's strictly a matter of partial eclipses and dark skies getting darker. I never travelled to see one.

I saw a really great lunar eclipse once when I was a kid. That was awesome.
