Fraser Gunn
Astrophotography

Taking a peak towards the unknown, finding a deep space object and having the privilage of the right tools and knowledge to photograph far more than the eye can see. Astrophotography taken from the Aoraki Mackenzie Dark Sky Reserve, Lake Tekapo, New Zealand using Astrograph Telescopes and special DSLR cameras attached to Astro night sky tracking mounts

Earth's Moon 90% illuminated at 372106 km's away

Earth's Moon made by merging 21 images taken with an iPhone

Astrophotography of the Moon with a cell phone camera seems to have the advantage over using a bigger DSLR camera, simply because you have more pixels per square mm and hence a higher resolution and you can take advantage of the extra magnification and optical corrections of the eyepeice. Luckily because the moon is so bright and big most of the time the auto functions of the cell phone camera will work. The hardest part is to make sure you are holding your phone level with the eyepeice and for the lens to be exactly in the middle of the eyepeice, to photography different areas of the Moon you move the telescope (not the phone) Images taken from the Canterbury University Mt John Observatory - Lake Tekapo, New Zealand. The Moon was 90% illuminated and 372106 km's away
