as a teenager i saw a similar picture, taken by the largest telescope at that time: the 5 m Mt Palomar telescope. Fascinated by it, i wrote them and they gave me the coördinates. I could never have dreamed that i - many years later - should become a picture that resembled the picture of that big telescope!

30cm newton F/4, 7 x 800sec, ST-8300

Some one requested to see a star through my 'big' telescope; i showed him Vega and then the started laughing aloud! I asked him why he laughed. He: "I see now the same as with my naked eye!"
