Title: Tonight's Super Moon
Post by: w1vtp on August 10, 2014, 08:54:45 PM
Better results than the Jul 12th one as I increased the ISO from 100 to 800.  Thank much to Nikon for the anti-shake

Bruce.  Where's yours?

Guys

Glad to see someone else was out there.  Dan, try underexposing a LOT  so the moon detail doesn't get washed out.  Otherwise that camera did a nice job

Joe - My Nikon tries to make what should be white, white.  I don't know yet how to turn that off.  Gotta get out the manual

It was too hazy/cloudy tonight here for good photos but I shot a couple.  I am planning to upgrade from my Canon 1DM2 to a 1DX shortly to take advantage of the huge improvements in sensor noise in the last few years.    Moon 1 was shot with a 400mm f5.6, Moon 2 with a 200 MM f2.8, both in manual mode with ISO set to 1000.  It was so cloudy I didn't bother setting up a tripod and shot them both handheld.

I saw the moon this morning at 5 AM in the western sky with a light blue background...looked like there was a small flat spot on the top of the moon...

Took the dog for a walk last night. We saw the moon; same one we saw the night before; we howled and then went inside.

I've got two questions:

1. Was this the "harvest" moon?

2. What causes the yellowish tint?

TIA.

Depends on your crop?  Tomatoes have peaked. 90 day corn is in and WV peaches are absolutely scrumptious right now.  -Martinsburg area down through Winchester, Va.

Yellowing all over disk caused by our atmosphere absorbing blues.  The higher in the sky the whiter the disk, the lower in the sky the yellower, just like the setting sun.

In Joe's pix you can see atmospheric differential chromatic dispersion, bluish fringe upper right of disk and reddish fringe lower left.  This because the moon has a finite angular size compared to its distance from the zenith to the horizon, so its 30 minutes of arc shows each limb at slightly different hues.

In Joe's pix you can see atmospheric differential chromatic aberration, bluish fringe upper right of disk and reddish fringe lower left.  This because the moon has a finite angular side compared to its distance from the zenith to the horizon, so its 30 minutes of arc shows each limb at slightly different hues.

Geez! Too complicated for me. I thought it was just the cheese maturing.  

From EarthSky:
"The Harvest Moon is the full moon closest to the autumnal equinox, and depending on the year, the Harvest Moon can come anywhere from two weeks before to two weeks after the autumnal equinox. For us in the Northern Hemisphere, the 2014 autumnal equinox comes on September 23, so the September 9 full moon counts as the Northern Hemisphere’s Harvest Moon.

The moon turns precisely full on Tuesday, September 9, at 1:38 Universal Time. Translating Universal Time to the clock time at United States’ time zones, that places the precise time for the September full moon on Monday, September 8, at 9:38 p.m. EDT, 8:38 p.m. CDT, 7:38 p.m. MDT or 6:38 p.m. PDT. See worldwide map below. The Harvest Moon is known for bringing a procession of moonlit nights!"

I guess once you start getting sucked into the black hole, it becomes some sort of space-time groundhog day.

Very close to a possible truth. Particles with information upon splitting in the event horizon might have each half fall into two different camps, those sucked in and those making it out.
A/C Stephen Hawking, this causes the eventual evaporation and death of black holes, because information escapes!  A process if modulated should be near and dear to our hearts.  ;D  Hawking radiation is now the named process.

If we lose our final fortresses, black holes, there Ain't no way out of increasing Entropy or running down of this Universe except for skipping over to the next hypothesized Brane. Heh, heh, anyone up for it?

There was a very good documentary of Stephen Hawking's life last night on PBS.
71 yrs old with ALS and still goes to work every day. Pretty much wholly paralyzed, on a ventilator at times and only by moving cheek muscles and eye motions able to communicate with the outside world via computer and really good word processor to speech software.
I had no idea of the type of everyday fortitude necessary for him to survive including the stuff no one talks about in everyday struggle and hygiene until similar experience in recent years.

If you guys haven't yet read it, by all means get a copy of his book, "A Brief Moment in Time."  ...fairly easy read and just getting it written and published was one of his driving ambitions and by his own words helped keep him alive.
