Re: Cause of Triple Sunrise (APOD 2009 August 4)

In the attached image, I took a flashlight and a scanner with two clear windows, much like a 2-pane window, and shined a flashlight through it and took a picture in the same orientation as the sun, window, and camera in the picture. What you will notice is the the reflected images go to the RIGHT, ...

Re: Cause of Triple Sunrise (APOD 2009 August 4)

Chris, they do match quite well. I tried lining them up using Photoshop but there's plenty of distortions and places where I'm not sure whether I'm seeing a part of the reflection or a cloud behind it so I didn't post it. I then tried outlining what I knew were clouds, what I thought were clouds, wh...

Re: Cause of Triple Sunrise (APOD 2009 August 4)

The clouds are impossible to outline. Not only due to the nature of clouds not having hard outlines but also because the sun's brightness and the camera's exposure obscures them beyond the point where one could determine the location of the clouds within a reasonable degree of accuracy. The color a...

Re: Cause of Triple Sunrise (APOD 2009 August 4)

Much as I agree that the more common cause of such an effect would be the multiple window panes, I am firmly on the side of atmospheric refraction in this case. As pointed out by some previous writers, the clouds interrupt the second and third images in a pattern consistent with interposition betwe...

Re: Cause of Triple Sunrise (APOD 2009 August 4)

I'm still convinced that it's window panes. The confusion with the clouds I think is happening because there are also some tangents with the clouds that make it appear as though the sun's reflections are happening behind them instead of at the window pane. This may have also tricked the photographer...

Re: Cause of Triple Sunrise (APOD 2009 August 4)

The reflections are behind the clouds because the original sun is behind the clouds. I wouldn't call it an obvious flaw in the window pane idea at all. It's impossible to see the form of the clouds which are in front of the original sun because it's so bright to the camera that the original shapes g...

I set out to find some more examples of triple sunsets taken by others. I used Google to translate this from Italian into crudely formed English.

Re: Jupiter another impact

I like to use Stellarium to help find things. As long as you set your position up accurately enough you can turn it on, key in what you are searching for and it will center on it. Then you just look in that direction in the real sky and find it. It's a lot easier than a static sky map for me. And mo...

Re: Solar Corona (2009 July 26)

Super saturating every colored bit of an image is actually the opposite of dynamic range, however. That's why I dislike it. If one's photo is to have high dynamic range, it ought to be not only in tonal value but also in hue as well. To pump the colors up too far is similar to doing a cheap contrast...

Re: Solar Corona (2009 July 26)

HDR photography seems to also mean you are supposed to super-saturate your photos and also be sure to include those weird fuzzy light and dark gradients when coming towards an edge to increase clarity but take it so far that it looks unnatural and kinda messed up. Thankfully, the APOD pic doesn't do...

The Sun is shining onto Earth from above, but onto the Moon from the left. Obviously, this picture is a clumsy fake. I have seen other pictures from the Apollo missions with a similar problem. Maybe that's why some people say the Moon landings never happened. I have a science experiment for you. Wa...

Re: The Milky Road (APOD 2009 June 13)

I really don't like the bottom half of the pic. It needs to be a lot less saturated and have some actual atmosphere on the horizon. That and the person's shadow is way, way too sharp... it should be incredibly diffuse given the broad, diffuse glow of the milky way. It's not like there's a moon there...
