Changed lines 5-7 from:

The inner brass circle is always parallel to the equator of the Earth, while the outer brass circle can be rotated so as to be parallel to the Ecliptic, at any given moment.

By rotating the entire instrument around the polar axis, the ecliptic ring is made parallel to the ecliptic at any given moment. There is a sighting bar that is pivoted to the ecliptic ring, which, in this position, can be rotated around the ecliptic pole. The sighting bar is rotated and is bought into the nearest alignment with the celestial object. The reading on the ecliptic ring, where the sighting bar rests, gives the Ecliptic Longitude of the object.

The entire brass instrument, with the two mounted circles, can rotate around an axis that is perpendicular to the masonry face on which the instrument rests.

There is a sighting bar that is pivoted to the ecliptic ring, which, in this position, can be rotated around the ecliptic pole. With this rotation of the sighting bar, the celestial object under observation is bought into view. The reading on the ecliptic ring, where the sighting bar rests, gives the Ecliptic Longitude of the object.

There is a quadrant attached to the sighting bar. There is a smaller sighting bar with this quadrant, which when aligned towards the celestial object, allows one to read off the celestial latitude of this object on the quadrant scale.

Changed lines 4-6 from:

Krantivrtta consists of two brass circles of equal diameter pivoted together at one point on their circumference. They have been pivoted together while maintaining an angle of 23.5 degrees between them.

The entire brass instrument, with the two mounted circles, can rotate around an axis that is perpendicular to the masonry face on which the instrument rests. The inner brass circle is always parallel to the equator of the Earth, while the outer brass circle can be rotated so as to be parallel to the Ecliptic, at any given moment. Using the sighting bar and arc placed on the outer brass circle, one can align the instrument towards the object to be observed and note its Celestial Longitude and Celestial Latitude on the corresponding scales.
