PS: I don't think the Canon 60D has such a long exposure time setting, from a quick search I think the maximum is 30 seconds. So it looks like it was 20 minute session (with just two photos) instead of a 20 minute exposure, as the article says.
Bulb Mode: This mode is similar to Manual exposure, in that it lets you control both shutter speed and lens aperture independently. However, instead of a fixed shutter speed, the 60D offers a Bulb shutter, allowing long exposures for as long as you hold the Shutter button down. (The top panel info display reports the elapsed time, from one to 999 seconds, as the exposure progresses.) To avoid camera shake, you can also control the exposure time using an RS-60E3 cabled remote switch, or one of three infrared remote controls -- the RC-6, RC-5, or RC-1.

If the maximum is 999 seconds (I don't understand if that's the maximum time or the limit on the display) it's not enough for 20 minutes, that's "only" 16 minutes and 39 seconds.
And I don't see anyone waiting 20 minutes pressing a button.

The article isn't clear about it, that's why I said "If, as it says on the article, that's a 20 minute exposure".
The article also has this:
Photographer Jason Reeve took the dazzling pictures from outside his north-west-facing bedroom window, in Chantry Court, with a 20-minute exposure.
If, instead of a 20 minute exposure, it was a 20 minute photo session, why only one or two photos?
