Great stuff Paul! Wish I had been able to see it, we were clouded out completely.

Thanks ... that was mostly shot through a thin cloud, but the sun is bright these were shot at f/5.6 @ 1/160 through film which is about the equivalent of a 14-stop filter (1/10,000 of the light gets through). I think it's surprisingly sharp considering that the film is not at all intended for this (rather meant to BLOCK light, esp. UV) and is not exactly of "optical glass" quality since I'm shooting through both the emulsion and a 4 mil Mylar base.

At least those are real sunspots and not just crud on the lens -- very helpful in lining-up the pictures!

If space.com wants to post it I'll try to finish it off (another 60-65 frames to go!) ...

ETA: I actually meant to post that the next total solar eclipse visible in North America is scheduled for August 21, 2017 (unless there's another government shutdown ... ;-) )

Yep, that's "Da Big One." The path of totality cuts right across the midsection of the country. I've already looked at potential locations to shoot from...

I was thinking the same. On the other hand, this site's vocabulary provides great cover :-).

Paul, great work on the animation!

Almost going straight over my head. Woo hoo! But I'm likely to try to find a more scenic location depending on how high or low the eclipse is on the horizon.

Check this out :-)

For pretty much all of us, it looks like the sun will be well above the horizon. Jason, you have some really great observing areas (dry, dry, dry) that aren't far away. I'm in a little more precarious position, since I will need to monitor predicted cloud cover very closely and potentially change my plans on a moment's notice based on weather reports. Could be interesting!

Yes. Cloud cover risk will be crucial. Eugene is generally pretty good in August, but not fool proof. Eastern Oregon may be safer. I've been waiting for this one for a while. It seems like a good excuse, however, to visit some national park that I hadn't been to before. :) Going to Bryce Canyon to see the annular eclipse of 2012 was a great experience. Too bad it just misses Yellowstone.

Perhaps we oughta plan a GTG around this?

Yeah, so everybody's pictures can be ruined together. :-)

I think spreading out to as many locations as possible would be more effective, if less fun ...

Philae is on the comet's surface! Resetta's lander has touched-down (three times, actually), but there are some problems ...

At this time, that's probably the most expensive photo ever. So far the "landing/crash" has been an extremely fortunate adventure, except for the part about landing in the shade.
One of the most fascinating factoids to me so far is that the lander only "weighs" about .4 oz on the astroid. If you were standing there, a good jump would either put you in orbit, or you would escape the astroid completely.

Yes, Philae had great acrobatics going down but failed to "spike" the landing. I hope that they can get it into a better configuration to get some sunlight before the batteries die.

It's not exactly an astronomy question, but is anyone else thinking about showing up at Cape Caneveral for the Dec 4th Delta IV launch with the Orion capsule test flight?
It's a sunrise shot, at around 7:00 AM.

Given that the temperature here this morning was like 9°F, Cape Canaveral is sounding pretty damn good, LOL. But, unfortunately, no, I don't have a launch window to escape this locality in that timeframe.

My Prius still gets pretty good milage, but California to Florida and back is still a bit too far ... :-)

Check out how this image was acquired -- "just a bit" of a different take on "panning" technique ...

Clear skies for another 48 hours. Then, snow and clouds. I might get to photograph some early appearances of the Geminids.

The burning question in every conspiracy theorist's mind: "What was happening on/near the moon, that they didn't want recorded, at that particular stretch of time, that the LROC would otherwise have picked up?" ;)

No comet Lovejoy joy in this thread? I got a fairly good look at his Smudgeness last night with a pair of binoculars.
12/31/2014 01:28:01 PM · #247
Might get a look tonight, though it will be pretty cold here... not as cold as last night though!
12/31/2014 08:36:01 PM · #248
I saw the news blurb about it just now. It's cloudy here now. Meanwhile, here's the link. It's supposed to be near Orion's feet tonight.
CBS , Lovejoy Comet

I found it just a bit ago. Very disappointed, but with the moon as bright as it is, I feel somewhat accomplished in locating it. Will try again after the 7th, as the moon should be a bit more cooperative.

We had a nice clear 60 degree f night last night, so I went out and watched the comet for a while. Even with a telescope, I could not see the tail.
It shows up slightly in this 20 second time exposure. It's cloudy here tonight.
