So we have a "official post your moon thread", and a star trails thread, and a milky way thread, why not a "official post your meteors thread"?
(I did a search and none exist)

Would be nice to see a single compilation of meteors.

Not to say individual meteors threads can't be made for you night out with details of your set-up, experiences, but post the keepers/highlights here.

I'll start with a re-post of yesterday mornings outing, I have some older and better ones will add later.

Took these Thursday Aug-7 morning 1:50am thru 5:30 am
Mostly clear night with a few stray clouds, taken on my Canon 70D, 11mm, f 2.8, 20 sec, ISO 1600. Taken with Tokina 11-16mm f/2.8 AT-X116 Pro DX II at 11mm, a very sharp optical lens.

1st meteor showed up around 1:58am, the image is slightly bright because the moon has not set below the horizon yet (moonset was 2:15am)

Here are 4 so far from tonight's Geminid meteor shower.

1:15am - 2am
My 1st time using Noels tools + CS5 to remove light pollution, learning on the fly.

These are all 25 sec exposures @ 15mm, ISO1600, T1i, no cropping.
In time sequence:

#1 1:19am

#2 1:34 am (small one located at rule 1/3's top/LH)

Perseid meteor shot Tues 8/10/2010

Talk about luck and timing!
I just came back from 4 day vacation in northern part of Michigan's lower peninsula, Hillman, about 1 hr south of Mackinac bridge.
This was a test shot Tues Aug 10th of Milky Way multiple exposure I was preparing for, as the 20 sec exposure went off I saw these 2 streaks and hoped they were in my field of view.

YES!

This is single 20 sec image shot with 15-85 @ 15mm, ISO 800, f 3.5, no stacking.
QUOTED IMAGE

Definitely active skies, in the 35 minutes I was shooting saw 9 meteorites, 1 brilliant with flower trail.
Good luck with clear skies and capturing some Perseid's everyone.
Dark skies (and no light pollution) helps.
I went outside just now here in SE Michigan, hoping to set-up camera for some images, too hazy skies so processing all the images from vacation (instead of sleeping).

Was rainy/cloudy all weekend, so went out early this morning Tues Aug-14, capture a few dim ones and this single bright one.

full image, T1i, ISO800, 25 sec, f3.5, 15mm:
[edit - I re-did the processing on this to bring out more of the meteor streak and the background stars. Much more visual than the prior posted image.]

Very nice jmchooper!

I've was up Sunday 10/21 since 4:30 am imaging with my DSLR, swapped batteries (6:10am).
Saw a few really nice ones with my eye that fortunately the camera was also on and pointed at....or so I thought
Once sunrise came I took the gear in, processed the 100's of images, and found 1 to post.
Also woke up my wife and boys, then took them outside to look "up" - on a chair - with them.

Seems I forget the eyes field of view is so much more than even a 15mm lens, and then the morning dew came and fogged my lens....

None posted??

Here's mine from this morning.
August 12, 2012 Perseid meteor shower, caught 3 next to the rising moon 3:30am - 5am. The long streak at bottom is actually an Iridium Satellite flare. You can see the 7 Sisters star cluster clearly here.
Canon T1i + 15-85 lens @ 15mm, ISO 800, f3.5, 20 sec exposures on tripod.
These were stacked together, sorry for the crooked horizon, I tried to get the moon across the middle of the sensor as it moved thru the sky......

Can you tell which way meteor went by the streak color direction?

Basic Q:

Can you tell which a way meteor went by the streak color direction?

The streak color is generally Red-yellow-blue, so which way is it going??

Red-yellow-blue or blue-yellow-red?

I would say Red-yellow-blue, based on knowing the origin for the Geminid's and the image below.....but want to really know.

These are Dec 14 2010 Geminid meteor shower, 5 streaks shown
QUOTED IMAGE

This is one of 370+ images used for my NASA APOD 8-5-2011 image, meteor streak 1/3 top/RH of image:

About the Geminids
http://en.wikipedia.or​g/wiki/Gemini's (external link)

As for the direction they are all moving from the top center out on your image. All meteor showers appear to come from the same general point in the sky where the Earth's atmosphere is impacting the debris, usually a comet trail, but in the case of the Geminid's they are caused by the object 3200 Phaethon, which is thought to be a Palladian asteroid. This would make the Geminids, together with the Quadrantids, the only major meteor showers not originating from a comet.

Incandescence is light produced from heat. Heat causes a substance to become hot and glow, initially emitting infrared, then red, orange, yellow, and white light as it becomes increasingly hotter. Sodium impurities burn yello -orange. Most of what we see is green from iron.

I hope this is pretty close to what you were looking for

pieq314 wrote in post #13409107 (external link)
Downward. They all originate from the same point, not converging to that point.

The color makes sense: the meteor gets hotter, and hotter means blue color.

mtbdudex wrote in post #13409657 (external link)
Thx guys, I understood they all originated from the same point.

Also get the temp/scale thing, what I did not grasp or remember from my High School days - sounds easy after the fact - is when we capture in images that color streak the meteor is in fact burning up at that temp in degrees kelvin, like the scale here shows.
That is safe to say, even for meteors of different material, that they all radiate the same color not based on their material but the temp of the material.
IMAGE NOT FOUND
| Byte size: ZERO | Content warning: NOT AN IMAGE


So, for the random meteor streaks that are captured one can get the direction by red-yellow-blue.

archer1960 wrote in post #13412392 (external link)
That color scale is for "black body" radiation. Different materials will definitely produce different colors in meteors, but they should always start at the lower temperature colors and move to the higher end as they heat up.

I "found it" when I was deleting aircraft lights from the individual images - lucky hit I guess.

Tried to capture Perseid meteor shower, about 72% of the Moon's visible disk illuminated making very bright seeing conditions.
Some wispy clouds, in 3+ hours this was best capture, other 2 were faint and behind clouds not worth sharing.
This taken Friday Aug-15 ISO: 1250 Exposure: 14.4 sec Aperture: 2.8 Focal Length: 11mm
