The entire group is crammed into a circle of less than 4 arc minutes
. The odd-one-out member is NGC 7320c, which can be spotted a few arc minutes
off to the northeast of this tight group.
The Trifid is found only 1 1/2 [degrees] north-northwest of M8 and is about 30 by 20 arc minutes
The field of view is identical to that of the XRT onboard Swift, 19 by 19 arc minutes
. The telescope is operated through the Talon telescope control software.
Series P has a backlash of less than three arc minutes
and an output torque of up to 1800 Nm.
Precision honing of the sun and planet gears produces high efficiency with a backlash of less than 8 arc minutes
and exact ratios of 3:1 to 64:1.
Visual resolution of the LCT projection system is 5.7 arc minutes
, significantly better than the 6.9 arc minutes
of the CMS.
Lalande 21185 stood out from the other stars Argelander was recording because it had moved: its position was a full 5 arc minutes
south of the one in Lalande's catalog.
Although successful in creating the star, Thompson still refers to the image--which measured some 1 to 2 arc minutes
across--more as a "blob' than a real point source.
This cigar-shaped galaxy, also known as Bennett 29, is a close neighbour of NGC 1808 situated 36 arc minutes
to the north-east.
Features include smooth and accurate motion, auxiliary logic power input, 20 microstep resolutions to 51,200 (full step, degrees, metric and arc minutes
), up to eight I/O lines, outputs configured for sourcing or sinking, and upgradeable firmware.
Approximately 8 by 6 arc minutes
in size, M27 shows well in a 4-inch telescope.
This gas and particulate envelope sometimes stretches as much as 5 arc minutes
in diameter (more than four times the Earth-Moon distance), and it varies in brightness by as much as a factor of four over time scales ranging from hours to years.
