by Ken Bates and Bonnie Ryder
On January 23, 2025, Peak Digital Imaging Society proudly hosted a presentation on the subject of "Deep Space: Astrophotography" given by Ken Bates and Bonnie Ryder. The presenters explained in detail the specialized equipment used in compiling the photographs along with many examples of the beautiful images that exist in deep space.

Deep space photography, also known as deep-sky astrophotography or deep space imaging, is a specialized type of photography that captures images of celestial objects in space.
How it works
- A telescope focuses light from distant objects onto a camera or detector.
- Multiple long exposures are taken of the same target.
- The images are stacked together to reduce noise and create a clearer, more detailed image.
Equipment
- A telescope with a star alignment routine to accurately position the telescope
- Recording instruments to improve imaging power
Challenges
- Light pollution
- Earth's rotation
- Objects are often very faint, so alignment accuracy is critical
What it reveals
- Colors and structures that are invisible to the naked eye
Please enjoy the presentation (in .pdf format). If your .pdf viewer permits "fit to page" or "fit to width" you can use them to zoom out of the images in order to see the whole photograph. You can then zoom in on the images to see the fine details.
