Aurora Storm.

[Zeder]

Hello All,

Well last night we had a very active solar wind storm. Here is a very small sample of what happened. C+C's welcome as always.

Enjoy!

2. Canon EOS 5D Mark II, f/2.8 @ 14 mm, 6s, ISO 1600



3. Canon EOS 5D Mark II, f/2.8 @ 16 mm, 13s, ISO 1600



4. Canon EOS 5D Mark II, f/2.8 @ 15 mm, 30s, ISO 1000



This is a reflection in a lake by the way! This is what the 15mm fisheye can do on a full frame sensor.

200+ more from last night here:

Thanks for looking!

Spectacular! Man, I wish we could see this down here in Houston.

I love the third shot ... it's excellent IMO.

They are all great, but that last one blows my mind

Agreed. That last one is spectacular. I think this might be the best aurora shot I've seen so far.

Yep, that last one is pretty cool, we don't get this in Seattle never mind Houston.

How the stars on the 14mm shot below:

1. Canon EOS 5D Mark II, f/2.8 @ 14 mm, 30s, ISO 1600

Are streaked in the corners but not towards the center, whereas on the 15mm FE shot:

4. Canon EOS 5D Mark II, f/2.8 @ 15 mm, 30s, ISO 1000

...there is not such streaking despite the same shutter speed. Am I interpreting this correctly in that the motion blur of the Earth's rotation is exaggerated at the edges of a rectilinear lens, whereas it's not for the FE.

I've noted in the past that I often prefer the FE distortion to the rectilinear distortion due to the stretched edges of the rectilinear, and wonder if this is another example of that.

Thanks for looking!

Thanks for sharing! Great pics!

It's not often one sees completely original images (at least in my own mental library). And that last one is like nothing I've ever seen. Totally awesome.

A rectilinear lens does, indeed, exaggerate the periphery. However, the streaks you see are not motion blur. They are simply distortion. Try extending all the streaks. They all converge to a single point, something you don't see from motion blur of the stars.

Lest someone object that when pointing north the polar star would be in the center, while that is almost true, the rest of the stars would be streaking perpendicularly to what you see here. Besides, the center of convergence is not north.

Amazing shots!, especially the last one with the FE; where were you btw?

I'm not one to gush over landscape photography, but dang, these are gorgeous. Nicely done!

I believe this is called coma. Some lenses are much better than others though

beautiful shots!

 

[Zeder]

Thank you all for your kind comments! I am glad that you enjoy the images!

Crocodile Gena,

As Victor Engel explained, thanks Victor, the star "stretching" at the periphery of the images taken with the 14mm rectilinear lens is primarily a function of lens distortion. That’s why I use the 14mm f2.8 and the 15mm Fisheye, they both have their own uses that are very different. For example, the 15mm FE will give a distorted landscape image if the horizon is not positioned in the middle of the image. Different tools for different images. I also use the 12-24mm Sigma and the 16-35mm f2.8. I know I have a lot of overlap but each lens has its own + - and the selection of lenses allow me to capture different perspectives of the same subject.

Cheers

Did you run any noise suppression on these shots?

that aurora 'rainbow' on the last one is cool with the fisheye

nah it's just lens defect, coma

lots of wide lenses do stuff like that near the corners

Thank you ALL for your comments!

I made the cover of http://www.spaceweather.com today!

Have a GREAT day all!
