Ascension & Parousia

When I looked at this picture, I couldn’t decide whether it was of Christ’s ascension or his return. I then remembered the angel asking the disciples:
“Men of Galilee, why do you stand looking into heaven? This Jesus, who was taken up from you into heaven, will come in the same way as you saw him go into heaven” (Acts 1.11).

I had put it in b&w but the orange glow doesn’t come off like in color.
