Astro-Physics Products Technical Drawings

  • Astro-Physics 900GTO Mount Head Dimensions. Illustrated article providing the dimensions of the Astro-Physics Model 900GTO computer controlled Mount Head as redesigned in 2005. Please note that these dimensions will vary somewhat depending on your latitude and so we quote dimensions for the head when in the Polar Aligned orientation for operation at three latitudes: 20, 42 and at 68 degree. This article shows several dimensions that are commonly requested by those who are planning to build an observatory and who need to know the Pole Aligned variations in the horizontal distance from the center of the mount base plate to the center of the declination axis that are caused by different latitude settings and by typical "parked" positions of the mount. Revised Oct 4, 2005. Download size is 467,251 bytes (in Acrobat Reader ".pdf" format).

  • Astro-Physics 1200GTO Mount Head Dimensions. Illustrated article providing the dimensions of the Astro-Physics Model 1200GTO computer controlled Mount Head as redesigned in late 2004; this will be similar for prior 1200GTO Mounts. Please note that these dimensions will vary somewhat depending on your latitude and so we quote dimensions for the head when in the Polar Aligned orientation for operation at three latitudes: 21.5, 42 and at 68 degree. This article shows several dimensions that are commonly requested by those who are planning to build an observatory and who need to know the Pole Aligned variations in the horizontal distance from the center of the mount base plate to the center of the declination axis that are caused by different latitude settings and by typical "parked" positions of the mount.
