Dhanuśarāgra (धनुशराग्र)
Dhanusharagra
Origin of Constellation
The term Dhanuśarāgra (धनुशराग्र) literally means tip of the arrow. Dhanu - bow, śara - arrow, agra - tip. This has been found in the catalogue of astrolabes translated from Persian. The names in these star lists of the dials have been coined based on their position. [1]The coordinates match with γ Sagittarii. The accuracy of the star dials cannot distiniguish between the two stars γ 1 and γ2. The image based on the artwork from wikicommons[2] (https://upload.wikimedia.org/wikipedia/commons/7/7e/Sidney_Hall_-_Urania%27s_Mirror_-_Sagittarius_and_Corona_Australis%2C_Microscopium%2C_and_Telescopium.png) represents the position - the red circle envelopes both the stars.
The two astrolabes which have this name engraved are C 006 (undated) and C(001, dated 1604CE) and identified as μ Sagittarii in the catalogue. In the latter, C001, the position actually corresponds to the supernova of 1604 CE. [3] [4]
This star name thus can be for γ1 Sagittarii.
