I was surprised to see not one but two other stars within 8 arcseconds of the central star with proper motions and parallax measurements essentially identical to that of the central star, within Gaia's measurement error.
GMx mounts can hold 12.5mm, 25mm and 50mm square optics of any thickness greater than 2mm, and offer up to 8[degrees] of total rotation in each axis, with a resolution as low as 3.2 arcseconds. All adjustments are accessed from the top of the mount to facilitate their use in space-constrained systems and instruments.
Each terrain parameter was produced at 1-arcsecond resolution and reduced to 3 arcseconds to serve the needs of the Soil and Landscape Grid of Australia, for compatibility with GlobalSoilMap specifications and to decrease data volume for easy distribution.
The planet's disc will exceed 45 arcseconds in diameter, so a telescope employing a magnification of just 40x will make it appear the same size as our Moon to the unaided eye.
