"September Aurora w/ Big Dipper"


Anchorage, US
          

From the night of September 29 - 30, Turnagain Pass, Alaska.

D300 - 24mm /2.0 AI MF - ISO 800 - /2.0 - 1.3 sec - cable release w/ tripod.



The forecast for the Aurora was indicating huge numbers that night but all we got was a few bands and the anticipated displays did not show.

I like Ursa Major framed in the Aurora.

Did you try longer exposures? Just curious about the effect you might get.

Good lens for that shot. It would be interesting to see a star field shot on FX to see how that lens deals with the corners, that being the widest f/2 lens available, and for reasonable money.

Neil,
The Harvest Moon was kickin' our butts that night. Longer exposures were washed out even with lower ISO or higher -stops. You can see some of that in the lower portion of the image. There is a slight bluing of the sky.

I have shot the 24mm on the D700 for Aurora as well as the 28mm /2.0 AI MF. Both do fairly well wide open but there can be a bit of distortion of bright lights near the edges unless I stop down. I am not sure if it is barrel or CA I see but the lights appear to have what I call "bat wings". The distortion is present on both the D300 and D700 with the 24mm /2, the 28mm /2, and the 35mm /1.4. I have not checked it on my 50mm /1.4 (I have both the MF and AF-D versions).

The only fast lens I have that performs great wide open in the dark is the Noct-Nikkor 58mm /1.2. I will use the Noct if I am going for a small section of the Aurora display.

Here is one from the same night with the Noct on the D700 - 58mm /1.2 - ISO 1600 - .5sec. The moon was really difficult as longer exposures were showing "glow".

The Aurora has to be really active to overcome the light of a 3/4 or greater Moon. I don't know why I keep trying to shoot in those conditions. It's like shooting at high noon.

But I keep trying and once in a while get a good image. And any night with Aurora is better than none.

I wasn't thinking about the moon.

If the distortion is symmetrical then it is a bit of astigmatism. If the distortion looks like small comets, all pointed toward the optical center, then it is coma. My understanding is that wider than f/4 or so almost all lenses will show one or the other. Lenses are basically designed to have one or the other- it's a designer's choice.

Except the Noct of course . You are blessed to have that lens.

Wonderful shots. So jealous of your location, having never seen the aurora. We'll have to experience it through your shots!
