The self-levelling mount SLM9 is intended for use with either a tripod or a monopod. It helps keep a camera and fisheye lens aligned to the horizon and North. This is necessary when taking hemispherical photos for use with Delta-T?€?s HemiView canopy analysis software. The SLM9 is designed for use with the Canon 60D digital SLR camera with a Sigma EX DC 4.5mm F2.8 circular fisheye lens.

For ease of use, the mount is equipped with the following features:
  • Bubble level and adjustable levelling weights
  • Compass for North/South alignment, viewable from above or below
  • Markers used to align hemispherical photos in HemiView, illuminated by the camera flashgun
  • Optional rugged carrying case
  • Optional monopod or tripod
