Setting Circles
The ETX models are equipped with R.A. and Dec. setting circles (13 and 16, Fig. 1a) to
aid in locating faint celestial objects
when the telescope has been polar aligned
. Setting cir-
cles emulate the celestial coordinates found on star charts or in sky catalogs. Any charted
object is easily located by coordinates in R.A. (in hours, minutes and seconds, from 0h 0m
0s to 23h 59m 59s) and Dec. (in degrees from 0° to ±90°).
With an ETX model polar aligned, use the Arrow keys to move the telescope in R.A. (left
and right keys) and Dec. (up and down keys).
Note:
The Dec. setting circle is located on the left arm of the telescope fork
