That's a unique view. Nicely done. You're getting a nice series here. It would make a great Photobook.

the streets are light light rivers going to a dark hole. Don't know how you managed it but its a shot that does draw you in.:thumbsup::thanx:

That's a wonderful photo Peter, and such an unusual vantage

Awesome, as usual.

What altitude is that from and how often is it that "clear" over the tropics?

Thanks.

Taken from 37,000 feet. Re: the weather, the inter-tropical convergence zone (ITZ) moves north and south
with the seasons, hence it is pretty clear this time of year at that latitude.

BTW, you can see an inversion layer quite clearly hovering over the city

The track overhead Manila was a little unusual..normally more westerly, but can and does vary with the upper level winds on the day.

Must've encountered CAT - look at the seagulls left and right of centre :) :P

Yep...juggling between aperture and motion blur...Canon's 24mm F1.4 shows coma up to about F2.8 (this was F1.7)

Thanks Peter,

I remember reading something about the variations in air corridors due to wind. A whole other world at 30,000 plus ft...

Can't believe how well defined the stars and milky way are above all that light. Mind boggling really. Something you couldn't imagine without a pic..... :scared2:

Indeed....not your "normal office view" but I guess something I've grown used to over the years. You often get almost perfect seeing and transparency out to + 200 Km close to the tropopause.

I also suspect scenes such as this, have not been documented much until now, as cameras with an ISO 400,000 capability have only recently become available.

Is this a single frame or a merge of two?

Single.

Impressive dynamic range at such an insanely high ISO.

Ah...my earlier post may have led some to believe I used ISO400,000...yes, the SonyA7s can indeed do that, but it was not used in this case...it was a paltry (!) ISO12,800

Wow on the image!

I missed Manila now that youve showed at from atop! :(

Great series Peter! Thoroughly enjoying them. Can't you open the little side window that pilots hang out of when parked at the gate and take your pics without distortion :D It's only 37000 feet!

Keep posting them.

Cheers
