This one. I meant focal length of 50mm at the time of the shot. I should have been more clear with the details. Sorry!
I used this:Canon EF
24-70mm f/2.8 L USM
Sure. Let me add some more context.
For up and down on each mission, the STS
plays an important role as there is an astronaut shooting approaches at the SLF making sure that in case of an abort (for up) or in a landing that the SLF is visible and that there is no rain clouds,fog etc cutting into the safety magins. Launch Control and Mission Control relies on the STA
to give real time feedback of weather to supplement what the USAF
weather squadron is providing from other sources.
As the orbiter rolls to wheels stop, the STA
has traditionally flown above her to check her out and also as a welcome gesture. On this particular mission (currently billed as Atlantis's last), this final gesture was very poignant. As the orbiter's last seconds of flight ticked down, there was a heightened sense of reverence watching the standard operations unfold. Atlantis emerged out of the last heading alignment circle opened air brakes and put her nose down to start her dive for the runway. At the same time, on the corresponding opposite side of the runway threshold, I picked out the STA
turning in a slower and delayed version of the shuttle path. So moments after Atlantis whizzed by me, I started tracking the STA
coming in right after her in the same flight attitude. The two images you see are her chasing after the orbiter which is still rolling down the runway at this point. Just at about wheels stop (perhaps the final one for Atlantis), N946NA gave her customary salute to Atlantis.
