About

 

 

Welcome.  My name is Greg Priestley and I'm an amateur astronomer and astroimager.

 

astroimaging.gallery is finally a single website that I can point people to that showcases some of my work, which is a mix of photos and videos.

 

Whilst I’ve had an interest in astronomy (and science) since high school, it wasn’t until the early 2000’s that I became active.

My astroimaging is shot with standard Digital SLR’s and tend to focus on wide fields of view of the night sky using standard camera lenses (i.e. not attached to telescopes).

Whilst at it’s most simplest this involves dropping a tripod down with your camera on it, focussing and shooting, these days the majority of my time is spent undertaking time lapses and in more recent times have added motion to provide an extra dimension to the footage.

Timelapses involve a lot of images and a lot of data.  Each individual frame of a time-lapse might be a photo with 12 to 30 seconds of exposure, shot across the entire night.  I can end up with well over 2,500 raw images in a night per camera, and sometimes I shoot three cameras at once.  It’s not uncommon to generate 200 Gb of images in a single night.

 

All for a few minutes of footage that many people will get bored with watching in a few seconds.  But if you sit back and really watch, there are so many things to see.  Some of the things you'll find here on my website include:

  • Meteors (with smoke trails)
  • Comets
  • Total solar eclipse
  • Partial solar eclipse
  • Satellites including geostationary, Iridium and iridium flares
  • International space station
  • Rockets
  • Galaxies
  • Atmospheric seeing differences
  • Horizon extinction
  • Sky glow / oxygen
  • Clouds, High clouds and really cool cloud structures
  • Lightning
  • Dew
  • Moon light pollution
  • Zodiacal lights
