Follow-up Materials

Here are follow-up materials for some of my recent public presentations.

Please don't hesitate to contact me with any questions or comments.

Astrophotography without a telescope
Presented to Brighton Astro on the 1^st February 2024.

• Lecture slides are available as a PDF file.
• Explore the superb astrophotography of Lavant Lavender and family.
• Pete of BrightonAstro suggests trying Photo Pills for planning shots.
• On the cycle home from the meeting, I took the following photographs:
  • One single frame - I took 20 shots in total.
  • The output after aligning and stacking those 20 images, using the free sequator software for Windows.
  • The final version using the free GIMP Image Processing software to change brightness, contrast, saturation and colour balance.
• When a camera is outside for long periods, it cools and so moisture forms on the camera and lens. One question after my talk was "How do you prevent this?". I use a lens heater which warms the lens just enough to prevent moisture from condensing onto the lens. Here is an example on Amazon.
• Collections of my own astrophotography:
  • Astrophotography highlights
  • Starry skies astrophotography
  • Star-trails astrophotography
