Catching the ISS with a 400 2.8 IS + 5.6x worth of TCs :)

I had to get out of bed a couple of hours before sunrise to set up my gear and try to catch the ISS, which was scheduled to make a bright mag -3.8 pass over Manila this morning.

Here's a shot taken with the 400 2.8 IS + 2x/2x/1.4x TCs (2263 mm) on the 7D. It's my best capture yet of the space bird using my birding lenses.

Simply awesome.

Absolutely incredible.

Excellent work. Now all you need for the next pass is a space-walker to give you a wave

reminds me of this review on amazon haha

Very cool, Romy.

did you practice "catch & release"?

Thanks everyone for the comments!

Awesome catch. way clearer than I though it would be.

Holy cow! That's an amazing pic! It must have been tough spotting it in the viewfinder at the focal length you were using.

that's as my son would say......too cool!

Thanks, gjl711, pat and dtw757!

Yes, acquiring a small fast moving target against a vast black BG (no reference points) is quite tough at such a narrow angle of view. I got lucky to find the ISS in the VF seconds after it appeared.

Excellent capture! Why not 8 - 2x TC's? lol

Let me see.... 8 - 2x TCs = 2^8 or 256x.

My 400 2.8 becomes 102.4 meters focal length at f/724. I think I'd need gamma rays to illuminate the subject instead of photons so the "light" can pass through that much glass.

that's excellent!

now time for an ISS in front of the sun / moon shot
