These days, a helium balloon and an automated camera can do the job, and a meteorological GPS device helps find the camera when it returns to terra firma.

“But in the end, it was almost a blessing, as it added a lot to the image.” Photographer Robert Franke likes the left-to-right flow and variety of galaxies in this view of the massive cluster 250 million light-years away.

He combined numerous images, totaling more than 20 hours of exposure from his home observatory and a remotely operated telescope in the Sierra Nevada mountain range of California.

The final result matches much of the detail in the Hubble photo, but at a smaller scale.

The Hubble Space Telescope’s 1995 image of the Pillars of Creation is one of the most iconic astronomy photographs.

Pennsylvania photographer Bill Snyder wanted to try a wide-angle photo of the same object.

And everyone benefits from the Internet to share ideas, learn from one another and even to use websites that calculate exactly where to be and when to get the perfect shot.

The pictures on these pages are just a few examples of how savvy amateurs can capture the beauty beyond our horizon.

In the days of film photography, one long exposure would do, but a digital camera cannot easily record long exposures without buildup of electronic noise, which degrades the image.

Now, modern photo software combines the data of many shorter exposures into one time-lapsed photo. It used to take a space program to see Earth’s curvature like this.

This image also shows remarkable detail of Io and Ganymede.

Peach photographed the moons separately and added them to this composite image, at the same scale. When the eclipsed sun rose over desolate Western Australia on May 10, 2013, Fabrizio Melandri of Italy was there to witness the unusual spectacle.
