My Telescope Series: Setting Circles (EQ Mount)

#SettingCircles, #Telescope, #EquatorialMount
If you’ve properly aligned your telescope to Polaris, The North Star, you can use your setting circle and your target’s Right Ascension/Declination to locate anything in the sky.

Your equatorial mount has three numbered circles. Two gauges are for the setting circles. One gauge is for the latitude dial.

First, you must calibrate your setting circles. Spot a star that is relatively close to your target. You must know this chosen star’s Right Ascension and Declination. Look through your telescope and center the star in your view. Now go to your setting circles and move them to read the accepted values.

Now that your setting circles are calibrated, you can move to your target. Loosen the Right Ascension and Declination knobs. Move the telescope first in Right Ascension and then in Declination until the setting circles read the Right Ascension and Declination of your target. Retighten the Right Ascension and Declination knobs.

Look through your finder scope and center your target. You can now observe your target through the main telescope.
